Search for radio transients and recent detection of radio sources in the RATAN-600 surveys of 1980–1994

Astrophysical Bulletin, 2016
In the paper we present the results of search for transient sources using the data from the surveys conducted onRATAN-600 at 7.6 cmin the time period of 1980–1994.We detected three events at a level of 3–5σ. A search for coincidenceswith detected transient events was carried out. Using the data from radio and optical surveys and the VizieR, SIMBAD, and

Radio Observations of Transient Gamma Ray Sources with the Westerbork Array

1994
Two γ-ray bursts have been rapidly imaged by COMPTEL (within ~ 6 hours of their occurrence) and their error boxes searched by Westerbork for evidence of a fading counterpart at radio wavelengths. These searches have revealed no likely candidate counterparts to the bursts.

Ultraviolet, optical, and radio observations of the transient X-ray source GRO J0422+32

AIP Conference Proceedings, 1993
We have monitored the early evolution of the transient X‐ray source GRO J0422+32 from approximately 2 weeks post‐discovery and into its early decline phase at ultraviolet, optical and radio wavelengths. Optical and ultraviolet spectra, obtained with the Perkins 1.8‐m telescope and with IUE respectively, exhibit numerous, but relatively weak, high ...

Discovery of a new transient radio source in the central region of M82

2009
We report the discovery of a new compact transient radio source in the central region of the starburst galaxy M82 with MERLIN at 4994MHz. The position measured for the transient source is (J2000) 09 55 52.5083, +69 40 45.420, with an astrometric error of 5mas in each coordinate.
