A sample of actively star forming H II galaxies has been observed in the radio continuum and several optical bands. These galaxies are currently undergoing very...

CCD photometry and MERLIN observations of M87 (Virgo A) have been used to study the variations of the radio to optical spectral index along the jet. In general...

Results from a multiwaveband study of the γ-ray-bright compact radio source 3C 454.3 are presented.

We report on recent radio observations of the newly-detected accreting millisecond X-ray pulsar, IGR J17511-3057 (ATels #2196, #2197, #2198, #2199, #2215, #2216...

We present the results on the optical morphology and structure of 25 low-luminosity radio galaxies. The radial dependence of parameters like the surface...

We report the discovery of a population of dominant galaxies in rich clusters in which the radio axis is aligned along the optical major axis.

General information is supplied about the present conditions of radio-stars and SAO-stars observation program, which are being carried out at the "Felix Aguilar...
