J/MNRAS/367/627     X-ray/NIR correlation for early-type galaxies (Ellis+, 2006)

Correlations of near-infrared, optical and X-ray luminosity for early-type galaxies. Ellis S.C., O'sullivan E. <Mon. Not. R. Astron. Soc., 367, 627-645 (2006)> =2006MNRAS.367..627E
ADC_Keywords: Galaxy catalogs ; X-ray sources ; Infrared sources ; Photometry Keywords: galaxies: fundamental parameters - galaxies: general Abstract: The relation between X-ray luminosity and near-infrared (NIR) luminosity for early-type galaxies has been examined. NIR luminosities should provide a superior measure of stellar mass compared to optical luminosities used in previous studies, especially if there is significant star formation or dust present in the galaxies. However, we show that the X-ray-NIR relations are remarkably consistent with the X-ray-optical relations. This indicates that the large scatter of the relations is dominated by scatter in the X-ray properties of early-type galaxies, and is consistent with early-types consisting of old, quiescent stellar populations. We have investigated scatter in terms of environment, surface brightness profile, Mg2, Hβ, Hγ line strength indices, spectroscopic age and nuclear Hα emission. File Summary:

Note (2): BT and mB from LEDA http://leda.univ-lyon1.fr/ or NED http://nedwww.ipac.caltech.edu, Note (3): From Jarrett et al. (2003AJ....125..525J, 2000AJ....119.2498J). Apparent magnitudes were converted to luminosities using the distances in column 2 (see the text for details). Note (4): Flag not explained in the paper, for NGC 3557, logLKs=logLH=10.89. Apparently, not a Ks or H luminosity. Note (5): All values are from O'Sullivan et al. (2001, Cat. J/MNRAS/328/461), however, some of these were derived from the catalogues Beuing et al (1999MNRAS.302..209B>, Fabbiano et al. (1992, Cat. J/ApJS/80/531) and Roberts et al (1991ApJS...75..751R) Note (6): Environment following O'Sullivan et al. (2001, J/MNRAS/328/461): F = field galaxy G = group member (based on Garcia (1993, Cat. J/A+AS/100/47) C = cluster member (based on Abell et al. (1989, Cat. VII/110) and Faber et al. (1989, Cat. VII/176) D = distance>70Mpc (for which environment cannot be accurately determined). Note (7): Environment defined as follows: G = Brightest group galaxies from Garcia (1993, Cat. J/A+AS/100/47) C = brightest cluster galaxies from Abell et al. (1989, Cat. VII/110) and and Faber et al. (1989, Cat. VII/176) D = dwarfs (LB<10^{9} LB☉) A = AGN from Veron-Cetty and Veron, 2001A&A...374...92V, VII/224, as given in O'Sullivan et al. (2001, Cat. J/MNRAS/328/461) Note (8): From HyperLEDA http://leda.univ-lyon1.fr/, where more than one value was available an average value is given. Note (9): From Pellegrini (1999A&A...351..487P), Faber et al.
