The Dark Side of ROTSE-III Prompt GRB Observations
S. A. Yost, F. Aharonian, C. W. Akerlof +22
We present several cases of optical observations during gamma-ray bursts (GRBs) which resulted in prompt limits but no detection of optical emission. These limits constrain the pro…
The Magnetar Nature and the Outburst Mechanism of a Transient Anomalous X-ray Pulsar
Tolga Guver, Feryal Ozel, Ersin Gogus +1
Anomalous X-ray Pulsars (AXPs) belong to a class of neutron stars believed to harbor the strongest magnetic fields in the universe, as indicated by their energetic bursts and their…
A Possible Magnetar Nature for IGR J16358-4726
S. K. Patel, J. Zurita, M. Del Santo +10
We present detailed spectral and timing analysis of the hard x-ray transient IGR J16358-4726 using multi-satellite archival observations. A study of the source flux time history ov…
X-ray Spectral Variations of U Gem from Quiescence to Outburst
T. Guver, C. Uluyazi, M. T. Ozkan +1
In this paper we report the discovery of a high energy component of the X-ray spectra of U Gem, which can be observed while the source is in outburst. We used Chandra and XMM-Newto…
The Prelude to and Aftermath of the Giant Flare of 2004 December 27: Persistent and Pulsed X-ray Properties of SGR 1806-20 from 1993 to 2005
Peter M. Woods, Chryssa Kouveliotou, Mark H. Finger +5
On 2004 December 27, a highly-energetic giant flare was recorded from the magnetar candidate SGR 1806-20. In the months preceding this flare, the persistent X-ray emission from thi…
X-Ray and Infrared Enhancement of Anomalous X-ray Pulsar 1E 2259+58
U. Ertan, E. Gogus, M. A. Alpar
The long term (~1.5 years) X-ray enhancement and the accompanying infrared enhancement light curves of the anomalous X-ray pulsar 1E 2259+58 following the major bursting epoch can…
