Simultaneous multi-wavelength observations of the TeV Blazar Mrk 421 during February - March 2003: X-ray and NIR correlated variability
Alok C. Gupta, B. S. Acharya, Debanjan Bose +2
In the present paper, we have reported the result of simultaneous multi-wavelength observations of the TeV blazar Mrk 421 during February March 2003. In this period, we have ob…
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…
Hardness ratio evolutionary curves of gamma-ray bursts expected by the curvature effect
Y. -P. Qin, C. -Y. Su, J. H. Fan +1
We have investigated the gamma-ray bursts pulses assumed to arise from relativistically expending fireballs. We find, due to the curvature effect, the evolutionary curve of the raw…
Unravelling the nature of HD 81032 - a new RS CVn Binary
J. C. Pandey, K. P. Singh, S. A. Drake +1
BVR photometric and quasi-simultaneous optical spectroscopic observations of the star HD 81032 have been carried out during the years 2000 - 2004. A photometric period of $18.802 \…
Studies of orbital parameters and pulse profile of the accreting millisecond pulsar XTE J1807-294
M. G. F. Kirsch, K. Mukerjee, M. G. Breitfellner +4
The accreting millisecond pulsar XTE J1807-294 was observed by XMM-Newton on March 22, 2003 after its discovery on February 21, 2003 by RXTE. The source was detected in its bright…
Binary corrected X-ray light curve of Cygnus X-3 : implications for the timing properties of the compact binary system
M. Choudhury, A. R. Rao, S. V. Vadawale +2
We study the binary corrected X-ray light curve of Cygnus X-3 using the RXTE-ASM data and RXTE-PCA data. We find that the X-ray template derived from the EXOSAT observations adequa…
