[25.07] Faint Radio Sources and Gamma Ray Bursts

G.I. Langston, A.H. Minter, T. M. Freismuth (NRAO)

We calculate the number density of faint radio sources that are expected in radio source surveys due to the isotropic emission of Gamma Ray Burst sources. The calculation assumes the beamed supernovae model for gamma ray burst sources detected in gamma rays, x-rays, optical and radio wavelengths. Since the radio wavelength emission is expected to be more isotropically radiated, the parent population of gamma Ray burst super novea are expected to more easily detected in radio wavelength surveys than at higher frequencies.

Our calculations show that the number of transient sources expected is small at the flux density limits of current surveys. We compare our models with the transient source counts detected in the NRAO Galactic Plane (GP) survey observations, a program to monitor the sky at 8.35 and 14.35 GHz. These observations used the NRAO/NASA Green Bank Earth Station to survey the galactic plane.
