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 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 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.
