Search for a Radio Counterpart to Grb 940301
نویسنده
چکیده
The COMPTEL instrument onboard the Compton Gamma{Ray Observatory imaged the bright gamma{ray burst GRB 940301 within 1.6 hours of the event, with a mean 1 error radius of 1.5. The error region was subsequently reened by combining the COMPTEL location with the arc derived from diierences in the event arrival time at the Ulysses and BATSE detectors. Westerbork observations of the COMPTEL error region began on March 4 1994 at 21 cm, however coverage of the reened position was not obtained until 32 days after the GRB occurrence, by which time the operating wavelength had changed to 92 cm. We have constrained the level of variability of sources within the triangulation arc-COMPTEL 2 error box region to be less than 40 mJy (5 upper limit) at 92 cm 41 days after the burst.

Two variable radio sources near the position of GRB 940301
We report on the results of a search for a radio counterpart to the strong gamma-ray burst GRB 940301. Observations with the Westerbork Synthesis Radio Telescope of the Compton Telescope error box region of GRB 940301 began on March 4, 1994, at 21 cm and April 2, 1994, at 92 cm. No flux density variations were detected at 92 cm above S = 10 mJy (5 σ) within a period of 1 to 4 months after the b...
متن کاملBima Observations of Gamma-ray Bursters Grb 970111 and Grb 970228
The Satellite per Astronomia X (BeppoSAX) is successfully producing small error boxes to gamma-ray bursts, permitting rapid follow-up multiwavelength searches for fading and quiescent counterparts. For GRB 970228 this led to the discovery of the first convincing fading counterpart. However, no counterpart was found for GRB 970111. In this Letter, we present our observations approximately 1 week...
متن کاملNo Radio Afterglow from the Gamma - Ray Burst of February 28 , 1997
We present radio observations of the gamma-ray burster GRB 970228 made with the Very Large Array (VLA) and the Owens Valley Radio Observatory (OVRO) spanning a range of postburst timescales from one to 300 days. A search for a time-variable radio source was conducted covering an area which included a fading X-ray source and an optical transient, both of which are thought to be the long waveleng...
متن کاملThe Discovery of the Radio Afterglow From the Optically Dim γ - Ray Burst of March 29 , 1998
We report on the discovery of a variable radio source, VLA J070238.0+385044, associated with the proposed x-ray counterpart, 1SAX J0702.6+3850 of GRB 980329. The source was monitored from one day after the burst to one month later at its variability, compactness and spectrum, we identify VLA J070238.0+385044 as the afterglow from GRB 980329. We interpret the rapid flux density variations as int...
متن کاملArchival search for recurrent activity at the position of the gamma - ray burst GRB 970228 optical counterpart
We have examined 8004 plates at the Harvard College Observatory Plate Collection searching for optical transient emission from the gamma-ray burst GRB 970228. This is the first archival search carried out so far for a gamma-ray burst with known transient optical emission. The total exposure time amounts to ∼ 1.1 yr. No convincing optical activity was found above 12.5 mag at the expected positio...
