ADC_Keywords: Galaxies, IR - Redshifts - Spectra, infrared Keywords: galaxies: evolution; galaxies: high-redshift galaxies: kinematics and dynamics; infrared: galaxies Abstract: In this paper, we follow up on our previous detection of nuclear ionized outflows in the most massive (log(M*/M)≥10.9) z∼1-3 star-forming galaxies (SFGs) by increasing the sample size by a factor of six (to 44 galaxies above log(M*/M)≥10.9) from a combination of the SINS/zC-SINF, LUCI, GNIRS, and KMOS3D spectroscopic surveys. Description: For the analysis in this paper, we included a total of 110 SFGs at z∼1-3 with near-IR integral field or slit spectroscopy covering the Hα+[NII] line emission from surveys carried out with SINFONI, KMOS, LUCI, and GNIRS. The targets for these surveys were originally drawn from rest-frame optical, UV, and near-IR selected samples in broadband imaging surveys with optical spectroscopic redshifts, and from stellar mass-selected samples with near-IR or optical spectroscopic redshifts.

Note (1): Kinematic classification of galaxy from Hα data, defined as follows: disk = rotation, disp = dispersion dominated kinematics, merger = perturbed motions in a major merger system, BLR = a compact AGN broad line region component. Note (2): Observing mode for the data used in this work, defined as follows: AO = adaptive-optics-assisted observations with FWHM resolution of 0.2"-0.3", s = seeing-limited observations with FWHM resolution of 0.5"-0.7", ss = seeing-limited observations with FWHM resolution of 0.5"-0.7", objects for which the kinematics are well resolved. Note (3): Identification of a broad nuclear emission component, defined as follows: 2.0 = a strong nuclear broad component, 1.0 = a clear nuclear broad component, 0.5 = a candidate nuclear broad component. Note (4): Specific SFR normalized to that of the main sequence of SFGs at the redshift and stellar mass of each object using the parameterization of Whitaker et al. (2012ApJ...754L..29W), applicable for log(M*/M)>10. Note (5): Flag on [NII]/Ha, defined as follows: n = no b = broad O = OH Note (6): The bolometric AGN luminosity is estimated either from the absorption corrected X-ray luminosity (as in Rosario et al. 2012A&A...545A..45R), or from the rest-frame 8µm luminosity of power-law mid-IR SEDs extrapolated to the total blue bump luminosity with AGN SEDs (Richards et al. 2006, Cat. J/ApJS/166/470), or an average. If only a mid-IR estimate is available, we consider this luminosity an upper limit to the AGN luminosity.
