A radio and near-infrared mini-survey of the MGRO J2019+37 complex
J. M. Paredes, J. Marti, C. H. Ishwara-Chandra +9
MGRO J2019+37 is an unidentified source of very high energy gamma-rays originally reported by the MILAGRO collaboration as the brightest TeV source in the Cygnus region. Despite th…
Deep low-frequency observations with the Giant Metrewave Radio Telescope: a search for relic radio emission
S. K. Sirothia, D. J. Saikia, C. H. Ishwara-Chandra +1
We present deep multifrequency observations using the Giant Metrewave Radio Telescope at 153, 244, 610 and 1260 MHz of a field centered on J0916+6348, to search for evidence of fos…
Radio detections towards unidentified variable EGRET sources
J. M. Paredes, J. Marti, C. H. Ishwara-Chandra +6
Context. A considerable fraction of the gamma-ray sources discovered with the Energetic Gamma-Ray Experiment Telescope (EGRET) remain unidentified. The EGRET sources that have been…
GRB 030329: 3 years of radio afterglow monitoring
A. J. van der Horst, A. Kamble, R. A. M. J. Wijers +7
Radio observations of gamma-ray burst (GRB) afterglows are essential for our understanding of the physics of relativistic blast waves, as they enable us to follow the evolution of…
Detailed study of the GRB 030329 radio afterglow deep into the non-relativistic phase
A. J. van der Horst, A. Kamble, L. Resmi +8
We explore the physics behind one of the brightest radio afterglows ever, GRB 030329, at late times when the jet is non-relativistic. We determine the physical parameters of the bl…
GMRT Observations of Microquasar V4641 Sgr
C. H. Ishwara-Chandra, A. Pramesh Rao
We report the GMRT observations of V4641 Sgr during the May 2002 outburst at radio frequencies of 610 and 244 MHz. This is the lowest frequency radio detection of this source. The…
