Title: Outflows & Feedback in Extremely Red Quasars

Abstract: Red quasars are candidate young objects participating in the early stages of massive galaxy formation. We recently completed a survey that finds ~200 high-redshift extremely red quasars (ERQs) in SDSS- III/BOSS based on rest-frame UV-MIR colors. These unique sources characteristically have extreme emission line properties that appear to result from extended outflowing emitting regions. We confirmed the connection to powerful outflows for 4 ERQs where VLT/XSHOOTER spectra reveal the broadest and most blueshifted [OIII] lines ever reported (with FHMMs and blueshifted wings reaching 5000km/s). These are large-scale outflows that might drive feedback to the host galaxies. We now propose GNIRS observations of 10 more ERQs to test the ubiquity of [OIII] outflows in the ERQ population, study the nature and origins of these outflows, and estimate their kinetic energies compared to models of feedback in galaxy evolution.
