\label{fig:quench_times}  Environmental quenching timescales for satellite galaxies across the observable range of stellar mass, $\mstar$ (top axis shows subhalo $\mpeak$ from abundance matching).  Blue circles show satellites of the MW and M31, obtained by matching the observed quiescent fractions in Figure~\ref{fig:quiescent_fraction} to rank-ordered virial-infall infall  times of satellites from the ELVIS simulations \citep{Wetzel2015} in 1-dex bins of $\mstar$. At $\mstar=10^{4-5}\msun$ (light blue), some satellite may have been quenched prior to infall via reionization, so interpret with care.  Error bars come from the 68\% uncertainty in observed quiescent fractions in Figure~\ref{fig:quiescent_fraction}.  Left panel uses time since first infall into the current MW/M31-like halo, while right panel uses time since first infall into \emph{any} host halo, including possible effects of group preprocessing.
