Low frequency radio spectrum and spectral turnover of LS 5039
Sagar Godambe, Subir Bhattacharyya, Nilay Bhatt +1
LS 5039, a possible black hole x-ray binary, was recently observed with Giant Meterwave Radio Telescope. The observed spectrum presented here shows that the spectrum is inverted at…
Very High Energy gamma-ray observations of Mrk 501 using TACTIC imaging gamma-ray telescope during 2005-06
S. V. Godambe, R. C. Rannot, P. Chandra +16
In this paper we report on the Markarian 501 results obtained during our TeV -ray observations from March 11 to May 12, 2005 and February 28 to May 7, 2006 for 112.5 hours with…
Very High Energy -ray and Near Infrared observations of 1ES2344+514 during 2004-05
S. V. Godambe, R. C. Rannot, K. S. Baliyan +20
We have observed the BL Lac object 1ES2344+514 (z = 0.044) in Very High Energy (VHE) gamma-ray and near-infrared wavelength bands with TACTIC and MIRO telescopes respectively. The…
Self-consistent computation of gamma-ray spectra due to proton-proton interactions in black hole systems
S. Bhattacharyya, N. Bhatt, R. Misra
In the inner regions of an accretion disk around a black hole, relativistic protons can interact with ambient matter to produce electrons, positrons and -rays. The resultant ste…
