Hello!!

WISE W1W2W3

2’

  z=0.844

r-[22] = 15.5

(Above:)  Quasar SDSS J091501.71+241812.1, at redshift z=0.844 which is an example of a new class of  “Extremely Red Quasars”, selected to be 1000 times more luminous in the observed 22um than in the r-band (rAB-[22]Vega>14) and reported in Ross et al. (2015, MNRAS, 453, 3932). This object has spectral features consistent with a “Type I” quasar, but has a WISE W4 band magnitude of 4.82±0.03 mag, suggesting considerable quantities of dust are present in the host galaxy.
