The X-ray emission from broad absorption line quasars

Pointed ASCA observations as well as archival ROSAT data are used for a stu dy of the X-ray emission of the three BAL Quasars LBQS 2212-1759, PG 1411+4 42, and PG 0043+039. All three objects are found to be X-ray quiet, possibl y due to substantial intrinsic absorption with N-H > 10(23) cm(-2) but migh t have intrinsically a more typical spectral energy distribution. This pict ure is supported by explicit spectral fits to the combined ROSAT/ASCA data of the nearby bright object PG 1411+442. An analysis of the large number of radio-quiet quasars not detected in the ROSAT All-Sky Survey indicates tha t perhaps only a small fraction of BAL quasars have not been recognized bef ore and that the number of intrinsically X-ray quiet quasars must be small.
