\label{fig:quench_times}
Environmental quenching timescales of satellite galaxies across the observable range of stellar mass,
$\mstar$.
Top $\mstar$ (top axis shows
the subhalo's subhalo $\mpeak$ from abundance
matching. matching).
Blue circles show times for satellites of the MW and M31, obtained by matching the observed quiescent fractions in Figure~\ref{fig:quiescent_fraction} to
the virial-infall times of satellites from the ELVIS simulations \citep{Wetzel2015} in
1-dex bins of $\mstar$.
Left panel
shows uses time since first infall into the current
MW/M31 MW/M31-like halos, while right panel
shows uses time since first infall into \emph{any} host halo,
thus including
the (potential) possible effects of group preprocessing.
Some satellites at $\mstar<10^5\msun$ At $\mstar=10^{4-5}\msun$ (light
blue) blue), some satellite may have been quenched prior to infall via reionization, so interpret their
quenching timescale with care.
Gray triangle shows lower limit for the
Large and Small Magellanic Clouds LMC/SMC system using
their infall time from
their its measured proper motion \citep{Kallivayalil2013}.
Red squares show
the timescale inferred for satellites with $\mstar=10^{8.5}$, $10^{9.5}\msun$ in SDSS \citep{Wheeler2014}, and green curve shows timescales inferred for more massive satellites in groups of $\mvir=10^{12-13}$ in SDSS \citep{Wetzel2013}.
The satellite dwarfs
in of the
Local Group MW/M31 quenched much more rapidly after infall than more massive
satellites, satellites in other hosts, with the
environmental quenching timescale
peaking being longest near Magellanic-Cloud-mass satellites.
