| 摘 要： | During the ROSAT All-Sky Survey (RASS; Voges 1992, 1997) about 80,000 X-ray sourceswith a detection likelihood 2 10 were detected, from which 18,811 sources having a PSPC countrate larger than 0.05 ets s--1 and detection likelihood 3 15 were compiled in the RASS-BSC(VOges et al. 1996a). More than 65% RASS sources remain unidentified (Voges et al. 1996b).The optical spectroscopic study of these RASS sources is essential for understanding them moreclearly.The idelltification of X-…

| Abstract: | For investigating the statistical properties of X-ray selected Active Galactic Nuclei(AGNs), we have carried out a program of optical identification of a selection of X-ray sources from ROSAT All Sky Survey Bright Source Catalogus(RASS-BSC)using the 2.16m telescope of Beijing Astronomical Observatory (BAO).In the preliminary observations, 23 new AGNs were discovered, of which 9 are quasars,and 14 are Seyfert galaxies. |
