... 435Snellen+ 15 GHz, and peak flux densities ranging from ~ 40 to ~ 900 mJy. Counts of GPS sources in our sample as a function of flux density have been compared with counts of large scale sources from WENSS scaled to 2 GHz, the typical peak frequency of our GPS sources. ... However, we note that the redshift distributions of GPS and large scale radio sources are different and that this hampers a direct and straightforward interpretation of the source counts. ...

... The VSOP Survey Continuum Source List . The radio sample for the VSOP continuum survey was defined to include all extragalactic radio sources with: . a total flux density at 5 GHz, S>=1.0 Jy . ... The sample also included all sources in the sky with a 5 GHz flux density S>5 Jy, regardless of spectral index and galactic latitude. ... The source would then be included in the VSOP sample (three of the sources were found with a flux density above 1 Jy and added to the sample). ...

1000 of these sources, however, remains a mystery; these are the so-called unassociated gamma-ray sources, with no known astrophysical counterpart at any other wavelength. While many LAT unassociated sources likely belong to known classes of objects (e.g. pulsars), a more exotic origin for some of these sources is also possible (e.g. dark matter annihilation). ... These results will aid further studies and follow-up observations of LAT unassociated sources. ...
