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…

Is the Lack of Pulsations in Low Mass X-Ray Binaries due to Comptonizing Coronae?

Ersin Gogus, M. Ali Alpar, Marat Gilfanov

The spin periods of the neutron stars in most Low Mass X-ray Binary (LMXB) systems still remain undetected. One of the models to explain the absence of coherent pulsations has been…

Exploring Broadband GRB Behavior During gamma-ray Emission

S. A. Yost, H. F. Swan, E. S. Rykoff +44

The robotic ROTSE-III telescope network detected prompt optical emission contemporaneous with the gamma-ray emission of Swift events GRB051109A and GRB051111. Both datasets have co…

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…
