Abstract:
We use surveys covering the redshift range 0.05<z<3.8 to explore
quiescent galaxy scaling relations and the redshift evolution of the
velocity dispersion, size, and dynamical mass at fixed stellar mass.
For redshift z<0.6, we derive mass-limited samples and demonstrate
that these large samples enhance constraints on the evolution of the
quiescent population. The constraints include 2985 new velocity
dispersions from the SHELS F2 survey. In contrast with the known
substantial evolution of size with redshift, evolution in the velocity
dispersion is negligible. The dynamical-to-stellar-mass ratio
increases significantly as the universe ages, in agreement with recent
results that combine high-redshift data with the Sloan Digital Sky
Survey. Like other investigators, we interpret this result as an
indication that the dark matter fraction within the effective radius
increases as a result of the impact of the minor mergers that are
responsible for size growth. We emphasize that dense redshift surveys
covering the range 0.07<z<1 along with strong and weak lensing
measurements could remove many ambiguities in evolutionary studies of
the quiescent population.
Description:
We use large samples from the SDSS and SHELS redshift surveys to study
the scaling between dynamical and stellar mass from redshift 0.1-0.6.
Following van de Sande+ (2013, J/ApJ/771/85) and
van de Sande+ (2015ApJ...799..125V 2015ApJ...799..125V), we select 93485 galaxies with
0.05<z<0.07 from SDSS DR7 (Abazajian+ 2009, II/294). See Section 2.1.
The F2 Hectospec data reported by Geller+ (2014, J/ApJS/213/35) were
reduced with an IRAF-based pipeline including the RVSAO
cross-correlation package. We have re-reduced these data with the
current pipeline, HSRED v2.0 and SDSS DR16.
Geller+ (2014) used the Hectospec 300-fiber instrument mounted on the
MMT, in 2004-2009, to acquire spectroscopy for galaxies in the DLS F2
field centered at RA=139.89°,DE=30.00°. See Section 2.2.
