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 obtained up to now suggest that persistent/silent microquasars such as LS 5039 are rare objects in our Galaxy, and indicate that future deeper surveys, and harder than the RBSC in X-rays, will play a fundamental role in order to discover them.

Resumen

Resumen

Presentamos los resultados de una búsqucda do nuevos microcuasares on bajas latitudes galácticas con base en una identificación cruzada entre el ROSAT Bright Source Catalogue (RBSC) do todo el cielo y NRAO VLA Sky Survey (NVSS) y las observaciones do seguimiento. Los resultados obtenidos hasta ahora sugieren que los microcuasares persistentes/silenciosos tales como LS-5039 son objetos raros on nuostra Galaxia e indican quе exploraciones futuras a mayores profundidades y en rayos X más duros que los del RBSC jugarán un papol fundamental en su descubrimiento.
