- Abstract
In an attempt to increase the number of known microquasars,
Paredes et al. (2002) have presented a long-term project focused
on the search for
new microquasars in the Galaxy. They performed a cross-identification between
X-ray and radio catalogs under very restrictive selection criteria for sources
with |b|<5o, and obtained a sample of 13 radio-emitting X-ray sources.
Follow-up observations of 6 of these sources with the VLA provided accurate
coordinates, which were used to discover optical counterparts for all of them.
We have observed these six sources with the EVN and MERLIN at 5 GHz. Five of
the six objects have been detected and imaged, presenting different
morphologies: one source has a two-sided jet, three sources have one-sided
jets, and one source is compact. With all the presently available information,
we conclude that two of the sources are promising microquasar candidates in our
Galaxy.
