Submillijansky Transients in Archival Radio Observations

We report the results of a 944 epoch survey for transient sources with archival data from the Very Large Array spanning 22 years with a typical epoch separation of 7 days. Observations were obtained at 5 or 8.4 GHz for a single field of view and …

Results of a search for new microquasars in the Galaxy

We present here the results of a search for new microquasars at low galactic latitudes, based on a cross-identification between the ROSAT all sky Bright Source Catalog (RBSC) and the NRAO VLA Sky Survey (NVSS) and follow-up observations. The results …

Optical spectroscopy of microquasar candidates at low Galactic latitudes

We report optical spectroscopic observations of a sample of 6 low- galactic latitude microquasar candidates selected by cross- identification of X-ray and radio point source catalogs for |b$^II$ | łeq 5 °. Two objects resulted to be of clear …
