Query: The impact of galactic properties and environment on the quenching of
  central and satellite galaxies: A comparison between SDSS, Illustris and
  L-Galaxies   We quantify the impact that a variety of galactic and environmental
properties have on the quenching of star formation. We collate a sample of
$\sim$ 400,000 central and $\sim$ 100,000 satellite galaxies from the Sloan
Digital Sky Survey Data Release 7 (SDSS DR7). Specifically, we consider central
velocity dispersion ($\sigma_{c}$), stellar, halo, bulge and disk mass, local
density, bulge-to-total ratio, group-centric distance and galaxy-halo mass
ratio. We develop and apply a new statistical technique to quantify the impact
on the quenched fraction ($f_{\rm Quench}$) of varying one parameter, while
keeping the remaining parameters fixed. For centrals, we find that the $f_{\rm
Quench} - \sigma_{c}$ relationship is tighter and steeper than for any other
variable considered. We compare to the Illustris hydrodynamical simulation and
the Munich semi-analytic model (L-Galaxies), finding that our results for
centrals are qualitatively consistent with their predictions for quenching via
radio-mode AGN feedback, hinting at the viability of this process in explaining
our observational trends. However, we also find evidence that quenching in
L-Galaxies is too efficient and quenching in Illustris is not efficient enough,
compared to observations. For satellites, we find strong evidence that
environment affects their quenched fraction at fixed central velocity
dispersion, particularly at lower masses. At higher masses, satellites behave
identically to centrals in their quenching. Of the environmental parameters
considered, local density affects the quenched fraction of satellites the most
at fixed central velocity dispersion.
