A sample of radio-loud QSOs at redshift ~ 4
J. Holt, C. R. Benn, M. Vigotti +5
We obtained spectra of 60 red, starlike objects (E< 18.8) identified with FIRST radio sources, S_{1.4GHz} > 1 mJy. Eight are QSOs with redshift z> 3.6.Combined with our pilot searc…
Decline of the space density of quasars between z=2 and z=4
M. Vigotti, R. Carballo, C. R. Benn +5
We define a new complete sample of 13 optically-luminous radio quasars M_AB(1450 Angstrom) < -26.9 mag and log P_1.4 GHz(W/Hz) > 25.7 with redshift 3.8 < z < 4.5, obtained by cross…
CO emission and associated HI absorption from a massive gas reservoir surrounding the z=3 radio galaxy B3 J2330+3927
Carlos De Breuck, Roberto Neri, Raffaella Morganti +10
We present results of a comprehensive multi-frequency study of the radio galaxy B3 J2330+3927. The 1.9" wide radio source, consisting of 3 components, is bracketed by 2 objects in…
