The radio properties of the braod-absorption-line QSOs

A VLA radio detection survey has been conducted for a large sample of broad-absorption-line (BAL) QSOs. Together with results from a similar, previous survey and a few observations from two other surveys, 68 BALQSOs have now been well observed with no strong radio sources detected. The absence of luminous radio sources among 68 known BALQSOs reported here, together with a complementary spectroscopic study which finds no BALQSOs among a large sample of radio-loud quasars, establishes a strong anticorrelation between luminous radio sources and the BALQSO phenomenon
