On the nature of the hard X-ray source IGR J2018+4043
A. M. Bykov, A. M. Krassilchtchikov, Yu. A. Uvarov +13
We found a very likely counterpart to the recently discovered hard X-ray source IGR J2018+4043 in the multi-wavelength observations of the source field. The source, originally disc…
Probing the Pulsar Wind Nebula of PSR B0355+54
Katherine E. McGowan, W. Tom Vestrand, Jamie A. Kennea +3
We present XMM-Newton and Chandra X-ray observations of the middle-aged radio pulsar PSR B0355+54. Our X-ray observations reveal emission not only from the pulsar itself, but also…
The early X-ray emission from GRBs
P. T. O'Brien, R. Willingale, J. Osborne +29
We present observations of the early X-ray emission for a sample of 40 gamma-ray bursts (GRBs) obtained using the Swift satellite for which the narrow-field instruments were pointe…
The Giant X-ray Flare of GRB 050502B: Evidence for Late-Time Internal Engine Activity
A. D. Falcone, D. N. Burrows, D. Lazzati +28
Until recently, X-ray flares during the afterglow of gamma ray bursts (GRBs) were a rarely detected phenomenon, thus their nature is unclear. During the afterglow of GRB 050502B, t…
Swift panchromatic observations of the bright gamma-ray burst GRB050525a
A. J. Blustin, D. Band, S. Barthelmy +12
The bright gamma-ray burst GRB050525a has been detected with the Swift observatory, providing unique multiwavelength coverage from the very earliest phases of the burst. The X-ray…
Swift, INTEGRAL, RXTE, and Spitzer reveal IGR J16283-4838
V. Beckmann, J. A. Kennea, C. Markwardt +9
We present the first combined study of the recently discovered source IGR J16283-4838 with Swift, INTEGRAL, and RXTE. The source, discovered by INTEGRAL on April 7, 2005, shows a h…
Swift observations of GRB050128: the early X-ray afterglow
S. Campana, L. A. Antonelli, G. Chincarini +33
Swift discovered GRB050128 with the Burst Alert Telescope and promptly pointed its narrow field instruments to monitor the afterglow. X-ray observations started 108 s after the tri…
Detection of Pulsed X-ray Emission from XMM-Newton Observations of PSR J0538+2817
Katherine E. McGowan, Jamie A. Kennea, Silvia Zane +5
We report on the XMM-Newton observations of the 143 ms pulsar PSR J0538+2817. We present evidence for the first detections of pulsed X-rays from the source at a frequency which is…
