- Abstract
- n a pilot search for high-redshift radio quasi-stellar objects (QSOs), we
have obtained spectra of 55 FIRST sources (S1.4GHz>1mJy) with very red
(O-E>3) starlike optical identifications. 10 of the candidates are QSOs
with redshifts 3.64. The
remaining 45 candidates comprise: one z=2.6 broad-absorption-line (BAL)
QSO; three low-redshift galaxies with narrow emission lines; 18 probable
radio galaxies; and 23 M stars (mainly misidentifications). The success
rate (high-redshift QSOs / spectroscopically-observed candidates) for this
search is 1/2 for S1.4GHz>10mJy, and 1/9 for S1.4GHz>1mJy. With an
effective search area of 4030deg2, the surface density of high-redshift
(z>4) QSOs discovered with this technique is 0.0015deg-2. (literal)
