Description

We have previously identified an excess population of predominantly red galaxies around a sample of 31 radio-loud quasars (RLQs) at 1<z<2. Here we show that these fields have a surface density of extremely red objects (EROs, with R-K>6) 2.7 times higher than the general field. Assuming these EROs are passively evolved galaxies at the quasar redshifts, they have characteristic luminosities of only ~L*. Only one of four RLQ fields has an excess of J-K-selected EROs with J-K>2.5; thus, those objects are mostly unrelated to the quasars. We also present new multiwavelength data and analyses on the fields of four of these quasars at z_q_~1.54, obtained to build more detailed pictures of the environments of these quasars and the galaxies within them.
