Next: Sample Properties Up: Sample Identification Previous: Comments on Individual Sources . Previously known serendipitous sources were selected by cross-correlating WGACAT with a variety of optical and radio catalogs, including the Ver?n-Cetty & Ver?n (1996) and Hewitt & Burbidge (1993) quasar catalogs, the 1 Jy (Stickel et al. 1994) and S4 (Stickel & K?hr 1994) radio catalogs, and the BL Lac catalog of Padovani & Giommi (1995b). ... Details of these 97 objects are given in Table 6. ...

... We use the first XMM serendipitous source catalogue (1XMM) to compile a sample of normal X-ray galaxies . ... We combine our emission line sample with earlier works forming the most comprehensive X-ray selected galaxy sample for the study of the X-ray luminosity to the H? luminosity - a well-calibrated star-formation indicator - relation. ... We find that the X-ray luminosity strongly correlates with the H? luminosity, suggesting that the X-rays efficiently trace the star-formation. | ...

Radio sources are among the most powerful of the family of Active Galactic Nuclei (AGN). ... The overall properties of radio sources are well predicted by analytical models of self-modifying evolution of the radio source which we have developed, and many of the more unusual structures observed can be reproduced using computational models. ...

Next: X--ray Quiet PMS Up: Contents Previous: Fits to Evolutionary . The X--ray selected PMS candidates may not constitute a complete list. The primary factor is the sensitivity limit, complicated by the vignetting in the field of the PSPC which was used to make the source list. ... In order to better understand the completeness of the X--ray data, photometry of every star in both regions was undertaken. ... The X--ray quiet sources are distributed evenly across the field (see Figure 8 ). ...
