Multi-Wavelength Studies of the Optically Dark Gamma-Ray Burst 001025A
K. Pedersen, K. Hurley, J. Hjorth +18
We identify the fading X-ray afterglow of GRB 001025A from XMM-Newton observations obtained 1.9-2.3 days, 2 years, and 2.5 years after the burst. The non-detection of an optical co…
Cygnus A
A. S. Wilson, K. A. Arnaud, D. A. Smith +2
We report Chandra imaging-spectroscopy and RXTE spectroscopy of the nearby, powerful radio galaxy Cygnus A. Various aspects of the results are discussed, including the X-ray proper…
Discovery of the CV ROTSE3 J015118.59-022300.1
D. A. Smith, C. Akerlof, M. C. B. Ashley +11
We report on the discovery of an outburst from a previously unknown high- latitude CV we designate ROTSE3 J015118.59-022300.1. The object was first detected on 2001 Oct 13.291 at m…
Localizations of Thirteen Gamma-ray Bursts by the All-Sky Monitor on RXTE
D. A. Smith, A. M. Levine, H. V. Bradt +9
The All-Sky Monitor (ASM) on the Rossi X-ray Timing Explorer (RXTE) has been used to localize thirteen confirmed X-ray counterparts to Gamma-Ray Bursts (GRBs) detected over three y…
Very High Energy Gamma-ray spectral properties of Mrk 501 from CAT Cerenkov telescope observations in 1997
A. Djannati-Atai, F. Piron, A. Barrau +31
The BL Lac object Mrk 501 went into a very high state of activity during 1997, both in VHE gamma-rays and X-rays. We present here results from observations at energies above 250 Ge…
Performances of the CAT imaging telescope and some preliminary results on Mkn 180 and the Crab
A. Barrau, R. Bazer-Bachi, H. Cabot +33
The CAT imaging telesope, which uses the Atmospheric Cherenkov Technique to observe TeV gamma-ray sources, has been operating since September 1996. Located in southern France, it f…
