Radio spectra for three QSOs

Naturevolume 247pages443444 (1974) | Download Citation



RADIO spectra are presented for three sources of current interest: 1548 + 114 (4C 1150) which is one of two quasars separated by about 5 arc s which have been suggested as possibly associated despite widely disparate redshifts1; 1331 + 170 which is a very luminous QSO with a rich absorption spectrum and suggested line locking between the emission spectrum and two separate absorption systems2; and 1442 + 101 (OQ172) which has the currently highest known redshift3, z = 3.53.
