Abstract:
We examine the evolution of the relation between stellar mass surface
density, velocity dispersion, and half-light radius --the stellar mass
fundamental plane (MFP)-- for quiescent galaxies at z<0.6. We measure
the local relation from galaxies in the Sloan Digital Sky Survey and
the intermediate redshift relation from ∼500 quiescent galaxies with
stellar masses 10≲log(M*/M☉)≲11.5. Nearly half of the
quiescent galaxies in our intermediate redshift sample are compact.
After accounting for important selection and systematic effects, the
velocity dispersion distribution of galaxies at intermediate redshifts
is similar to that of galaxies in the local universe. Galaxies at
z<0.6 appear to be smaller (≲0.1dex) than galaxies in the local
sample. The orientation of the stellar MFP is independent of redshift
for massive quiescent galaxies at z<0.6 and the zero-point evolves by
∼0.04dex. Compact quiescent galaxies fall on the same relation as the
extended objects. We confirm that compact quiescent galaxies are the
tail of the size and mass distribution of the normal quiescent galaxy
population.
Description:
We derive the stellar mass fundamental plane (MFP) from a sample of
local galaxies taken from the SDSS Legacy Survey. The nominal spectral
range of the observations is 3800-9200Å and the spectral resolution
is R∼1500 at 5000Å.
We examine the redshift evolution of the MFP using data from the
1.6deg2 COSMOS field. We have conducted a redshift survey of the
field (Damjanov+ 2015ApJ...815..104D 2015ApJ...815..104D; 2016, in prep.) using Hectospec
on the MMT to observe ∼2500 objects selected from the UltraVISTA
catalog of Muzzin et al. (2013ApJS..206....8M 2013ApJS..206....8M). Our typical
integration time was ∼1hr and the data were obtained under variable
conditions in February and April of 2015.
