Evolution and black hole feedback of high-excitation and low-excitation radio galaxies in XXL-S Description: Paper XVII. X-ray and Sunyaev-Zel'dovich properties of the redshift 2.0 galaxy cluster XLSSC 122. We present results from a 100ks XMM-Newton observation of galaxy cluster XLSSC 122, the first massive cluster discovered through its X-ray emission at z 2. The data provide the first precise constraints on the bulk thermodynamic properties of such a distant cluster, as well as an X-ray spectroscopic confirmation of its redshift. We measure an average temperature of kT=5.0+/-0.7keV; a metallicity with respect to solar of Z/Z_sun_=0.33^+0.19^_0.17_, consistent with lower-redshift clusters; and a redshift of z=1.99^+0.07^_0.06_, consistent with the earlier photo-z estimate. The measured gas density profile leads to a mass estimate at r500 of M500=(6.3+/-1.5)10^13^M_sun_. From CARMA 30 GHz data, we measure the spherically integrated Compton parameter within r500 to be Y500=(3.6+/-0.4)10^-12^. We compare the measured properties of XLSSC 122 to lower-redshift cluster samples, and find good agreement when assuming the simplest (self-similar) form for the evolution of cluster scaling relations. While a single cluster provides limited information, this result suggests that the evolution of the intracluster medium in the most massive, well-developed clusters is remarkably simple, even out to the highest redshifts where they have been found. At the same time, our data rearm the previously reported spatial oset between the centres of the X-ray and SZ signals for XLSSC 122, suggesting a disturbed configuration. Higher spatial resolution data could thus provide greater insights into the internal dynamics of this system. list17.dat: FITS reduced images & spectra of XLSSC 122. Paper XVIII. ATCA 2.1 GHz radio source catalogue. atcacomp.dat: The table contains the component catalogue of all 6350 components detected with S/N>=5 in the full Australia Telescope Compact Array 2.1 GHz continuum survey of the XXL-South field. The observations covered the entirety of the 25 square degree XXL-South field. The radio data has an angular resolution of 5.4 x 4.2 square arcsec and a median rms of 41 uJy per beam. There are 1677 resolved components. atcasrc.dat: The table contains the source catalogue of all 6287 sources detected with S/N>=5. There are 1626 resolved sources, of which 48 are multiple-component objects. The tables contain various observed parameters of the radio sources, such as position, peak flux density and signal-to-noise ratio. Paper XX. The 365 cluster catalogue. In the currently debated context of using clusters of galaxies as cosmological probes, the need for well-defined cluster samples is critical. The XXL Survey has been specifically designed to provide a well characterised sample of some 500 X-ray detected clusters suitable for cosmological studies. The main goal of present article is to make public and describe the properties of the cluster catalogue in its present state, as well as of associated catalogues of more specific objects such as super-clusters and fossil groups. Following from the publication of the hundred brightest XXL clusters, we now release a sample containing 365 clusters in total, down to a flux of a few 10^-15^erg/cm2/s in the [0.5-2]keV band and in a 1' aperture. This release contains the complete subset of clusters for which the selection function is well determined plus all X-ray clusters which are, to date, spectroscopically confirmed. In this paper, we give the details of the follow-up observations and explain the procedure adopted to validate the cluster spectroscopic redshifts. Considering the whole XXL cluster sample, we have provided two types of selection, both complete in a particular sense: one based on flux-morphology criteria, and an alternative based on the [0.5-2]keV flux within one arcmin of the cluster centre. We have also provided X-ray temperature measurements for 80% of the clusters having a flux larger than 9x10^-15^erg/cm2/s. xxl365gc.dat: We provide the list of spectroscopically confirmed C1 and C2 clusters of galaxies from the XXL-365-GC catalogue, i.e. tab. 5 of the article. It includes only clusters with a spectroscopic validation. For these clusters, we provide (when available) a direct determination of the X-ray gas mass within a 500kpc aperture, of the r_500 radius (the radius of the sphere inside which the mean density is 500 times the critical density of the Universe at the cluster's redshift), of the temperature within 300kpc, of the X-ray luminosity and uncertainty in the [0.5-2]keV rest-frame energy range and within the r_500 radius, and the X-ray flux and uncertainty in the [0.5-2] keV band and within a 60 arcsec radius. NOTE: the formatting of Mgas500kpc, T300kpc and LXXL500MT (and associated errors) in the original issue of this file was partially inappropriate while XXL paper authors used the correctly formatted values. In Mar 2019 we provide a revised version with the correct formatting. Paper XXII. The XXL-North spectrophotometric sample and galaxy stellar mass function in X-ray detected groups and clusters We have built a complete spectrophotometric sample of galaxies within X-ray detected, optically spectroscopically confirmed groups and clusters (G&C), covering a wide range of halo masses at z<=0.6 In the context of the XXL survey, we analyse a sample of 164 G&C in the XXL-North region (XXL-N), at z<=0.6, with a wide range of virial masses (1.24x10^13^<= M_500(M_sun_)<=6.63x10^14^) and X-ray luminosities (2.27x10^41^<=L^XXL^_500_(erg/s)<=2.15x10^44^). The G&C are X-ray selected and spectroscopically confirmed. We describe the membership assignment and the spectroscopic completeness analysis,and compute stellar masses. As a first scientific exploitation of the sample, we study the dependence of the galaxy stellar mass function (GSMF) on global environment. We present a spectrophotometric characterisation of the G&C and their galaxies. The final sample contains 132 G&C, 22111 field galaxies and 2225 G&C galaxies with r-band magnitude <20. Of the G&C, 95% have at least three spectroscopic members, and 70% at least ten. The shape of the GSMF seems not to depend on environment (field versus G&C) or X-ray luminosity ( used as a proxy for the virial mass of the system). These results are confirmed by the study of the correlation between mean stellar mass of G&C members and L^XXL^_500_.We release the spectrophotometric catalogue of galaxies with all the quantities computed in this work. As a first homogeneous census of galaxies within X-ray spectroscopically confirmed G&C at these redshifts, this sample will allow environmental studies of the evolution of galaxy properties. xxlngal.dat: The final catalogue contains all the properties described in this paper for the subsample of galaxies with 0<z<=0.6, r<=20 and a derived stellar mass estimate. The released sample is composed of 24336 galaxies, both in the field and in G&C, and the contribution of the different surveys is the following: 95% of redshifts come from GAMA (23178 galaxies out of 24336), 3% are from SDSS_DR10 (763 galaxies out of 24336) and the rest come from ESO Large Programme + WHT XXL dedicated observational campaigns (0.5%, 115 galaxies out of 24336) and VIPERS (0.2%, 48 galaxies out of 24336). The catalogue contains the astrometry from CFHTLS, the redshift, the name of the parent catalogue/survey, the "origin flag" and "quality flag" that were introduced in Sect. 2.3 of the paper, all the membership related quantities, absolute magnitudes, stellar masses and completeness values. Paper XXVI. Optical and near infrared identifications of the ATCA 2.1GHz radio sources in the XXL-S Field. atca.ctpt.dat : This file report the optical, near infrared and X-ray counterparts of the radio sources detected in the XXL-S Field. The radio data have been obtained with the Australia Telescope Compact Array (ATCA) at 2.1GHz with a resolution of 4.76 arcsec. The optical data used have been obtained at the Cerro Tololo Inter-American Observatory (CTIO) with the MOSAIC II imager during the Blanco Cosmological Survey (BCS) in the g,r and i bands and with the Dark Energy Camera (DECam) in the g,r,i and z bands. The infrared data have been obtained in the J,H and K bands during the Vista Hemisphere Survey (VHS), a public ESO large programme survey. The X-ray data have been obtained with the XMM-Newton X-ray Telescope as part of the XMM-Newton Extragalactic Survey. The Likelihood Ratio technique has been used to associate the counterparts to the radio sources. Paper XXVII. The 3XLSS point source catalogue. We present the version of the point source catalogue of the XXL survey that was used, in part, in the first series of XXL papers. In this paper we release, in our database in Milan and at CDS: (i) the X-ray source catalogue with 26056 objects in two areas of 25 deg^2^; (ii) the associated multiwavelength catalogues with candidate counterparts of the X-ray sources in the infrared, near-infrared, optical and ultraviolet (plus spectroscopic redshift when available); and (iii) a catalogue of spectroscopic redshifts recently obtained in the southern XXL area. We present also the basic properties of the X-ray point sources and their counterparts. Other catalogues described in the second series of XXL papers will be released contextually, and will constitute the second XXL data release. 3xlss.dat: We provide the source list for the full area (2x25 square degrees) of both XXL fields (XXL-N and XXL-S), with a total of 26056 point-like or extended sources above a detection likelihood of 15 in either 0.5-2 or 2-10 keV bands. The 3XLSS table at CDS contains the main X-ray parameters, while further parameters and data products (X-ray images and exposure maps) are available in the Milan XMM-LSS database site. For multiwavelength data see associated tables 3XLSSOPTN and 3XLSSOPTS. 3xlsoptn.dat: We provide the multiwave counterpart list for the northern area (XXL-N) of the XXL fields with a total of 14168 X-ray sources with zero, one or more potential counterparts. Standardized AB magnitudes are given for various bands from SDSS, CFHT, VISTA, UKIDSS, WIRcam, IRAC, GALEX and WISE surveys. The preferred (primary) counterpart has a rank from 0.0 to 1.0, while higher ranks are for secondary counterparts. In addition spectroscopic redshift and association with SIMBAD and NED are given where available. Further parameters and data products (FITS thumbnail images, SIMBAD and NED links) are available in the Milan XMM-LSS database site. For X-ray data in both XXL-N and XXL-S areas see associated table 3XLSS. 3xlsopts.dat: We provide the multiwave counterpart list for the southern area (XXL-S) of the XXL fields with a total of 11888 X-ray sources with zero, one or more potential counterparts. Standardized AB magnitudes are given for various bands from BCS, DECam, VISTA, IRAC, GALEX and WISE surveys. The preferred (primary) counterpart has a rank from 0.0 to 1.0, while higher ranks are for secondary counterparts. In addition spectroscopic redshift and association with SIMBAD and NED are given where available. Further parameters and data products (FITS thumbnail images, SIMBAD and NED links) are available in the Milan XMM-LSS database site. For X-ray data in both XXL-N and XXL-S areas see associated table 3XLSS. xxlaaoz.dat: In the framework of the publication of the 3XLSS point source catalogue, we provide also the redshifts obtained with the AAOmega spectrograph in 2016 for 3572 sources in the XXL-S field, supplementing those published in XXL Paper XIV (Lidman et al., 2016PASA...33....1L) and CDS IX/49/xxlaaoz). The AAOmega spectrograph in conjunction with the two-degree field (2dF) fibre positioner on the AAT was used to measure redshift of sources in the XXL-S field during two campaigns in 2015 and 2016. The 2015 results were published in XXL Paper XIV (Lidman et al., 2016PASA...33....1L) and CDS IX/49/xxlaaoz), while the newer 2016 results for 3572 objects are published with the present paper. xxlpoint.dat: The table (B.1 in Paper XXVII, Chiappetti et al.) is a list of all XMM survey-type observations(<=AO-10) in the XXL fields, providing the match between the internal naming and the ESA XXM log,the coordinates and useful exposure times of the XMM pointings, their quality and ancillary information. The initial columns of the table are identical to the one published with XXL Paper I (Pierre et al., 2016A&A...592A...1P and IX/49/xxlpoint). The astrometric offsets used in XXL data releases DR1 and DR2 were added in this new version of the table. Paper XXVIII. Galaxy luminosity functions of the XXL-N clusters. xxlnbcg.dat: Properties of the brightest cluster galaxies (BCGs) in our cluster sample, ordered by increasing redshift. Paper XXIX. GMRT 610 MHz continuum observations. xxl_gmrt.dat: The table presents a catalogue of 5434 sources detected at >=7 rms within the 25 square-degree GMRT-XXL-N 610MHz radio continuum survey, conducted at 50cm wavelength with the Giant Metrewave Radio Telescope (GMRT) towards the XXL Northern field (XXL-N). We combined previously published observations of the XMM-Large Scale Structure (XMM-LSS) field, located in the central part of XXL-N, with newly conducted observations towards the remaining XXL-N area, and imaged the combined data-set using the Source Peeling and Atmospheric Modeling (SPAM) pipeline. The final mosaic encompasses a total area of 30.4 square degrees, with rms<150uJy/beam over 60% of the area. The rms achieved in the inner 9.6 square degree area, enclosing the XMM-LSS field, is about 200uJy/beam, while that over the outer 12.66 square degree area (which excludes the noisy edges) is about 45uJy/beam. The resolution of the final mosaic is 6.5-arcsec. More details about the catalog, including its verification, reliability, and false detection rate can be found in the paper. list.dat: FITS images of the XXL-North field: continuum radio mosaic from observations with the Giant Meterwave Radio Telescope (GMRT) at 610MHz, and the corresponding noise map. Paper XXXIV. Double irony in XXL-North. Two prominent radio galaxies were identified in a visual examination of the mosaic of XXL-North obtained with the Giant Metrewave Radio Telescope at 610MHz. Counterparts were searched for in other bands. Spectroscopic redshifts from the GAMA database were used to identify clusters and/or groups of galaxies, estimate their masses with the caustic method, and quantify anisotropies in the surrounding galaxy distribution via a Fourier analysis. Both radio galaxies are of FRI type and are hosted by early-type galaxies at a redshift of 0.138. The first radio source, named the Exemplar, has a physical extent of about 400kpc; it is located in the cluster XLSSC112, which has a temperature of about 2keV, a total mass of about 10^14^ solar masses, and resides in an XXL supercluster with eight known members. The second source, named the Double Irony, is a giant radio galaxy with a total length of about 1.1Mpc. Its core coincides with a cataloged point-like X-ray source, but no extended X-ray emission from a surrounding galaxy cluster was detected. However, from the optical data we determined that the host is the brightest galaxy in a group that is younger, less virialized, and less massive than the Exemplar's cluster. A friends-of-friends analysis showed that the Double Irony's group is a member of the same supercluster as the Exemplar. There are indications that the jets and plumes of the Double Irony have been deflected by gas associated with the surrounding galaxy distribution. Another overdensity of galaxies (the tenth) containing a radio galaxy was found to be associated with the supercluster. Radio galaxies can be used to find galaxy clusters/groups that are below the current sensitivity of X-ray surveys. list.dat: FITS images of two radio galaxies from observations with the Giant Meterwave Radio Telescope (GMRT) at 610MHz. Paper XXXVI. Evolution and black hole feedback of high-excitation and low-excitation radio galaxies in XXL-S atcaclas.dat: This file contains the core multiwavelength quantities and flags used to classify the 1.4GHz radio sources cross-matched to an optical counterpart in the XXL-S field. There are 4758 radio sources with counterparts. The radio data have been obtained with the Australia Telescope Compact Array (ATCA) at a central frequency of 2.1GHz with a resolution of 4.76-arcsec. The mid-infrared (MIR) magnitude data have been obtained from the WISE all-sky survey and the Spitzer-IRAC Spitzer South Pole Telescope Deep Field (SSDF). All other optical/IR magnitudes are derived from SED fits. The optical spectra data were obtained with the AAOmega spectrograph on the Australian Astronomical Telescope.
