Panchromatic observations of the textbook GRB 110205A: constraining physical mechanisms of prompt emission and afterglow

W. Zheng, R. F. Shen, T. Sakamoto +56

We present a comprehensive analysis of a bright, long duration (T90 ~ 257 s) GRB 110205A at redshift z= 2.22. The optical prompt emission was detected by Swift/UVOT, ROTSE-IIIb and…

Discovery of the Onset of Rapid Accretion by a Dormant Massive Black Hole

D. N. Burrows, J. A. Kennea, G. Ghisellini +53

Massive black holes are believed to reside at the centres of most galaxies. They can be- come detectable by accretion of matter, either continuously from a large gas reservoir or i…

A Statistical Comparison of the Optical/UV and X-ray Afterglows of Gamma-Ray Bursts using the Swift Ultra-violet Optical and X-ray Telescopes

S. R. Oates, M. J. Page, P. Schady +11

We present the systematic analysis of the UVOT and XRT light curves for a sample of 26 Swift Gamma-Ray Bursts (GRBs). By comparing the optical/UV and X-ray light curves, we found t…

Suzaku Observations of Luminous Quasars: Revealing the Nature of High-Energy Blazar Emission in Quiescent States

LAT Collaboration, A. A. Abdo, F. Tavecchio +5

We present the results from the Suzaku X-ray observations of five flat-spectrum radio quasars (FSRQs), namely PKS0208-512, Q0827+243, PKS1127-145, PKS1510-089 and 3C 454.3. All the…

Swift observations of the SFXT SAX J1818.6-1703 in outburst

P. Romano, L. Sidoli, P. Esposito +7

We present the Swift observations of the supergiant fast X-ray transient (SFXT) SAX J1818.6-1703 collected during the most recent outburst, which occurred on May 6 2009. In particu…

The first broad-band X-ray study of the Supergiant Fast X-ray Transient SAXJ1818.6-1703 in outburst

L. Sidoli, P. Romano, P. Esposito +7

The Supergiant Fast X-ray Transient (SFXT) SAXJ1818.6-1703 underwent an outburst on 2009 May 6 and was observed with Swift. We report on these observations which, for the first tim…
