The soft X-ray blast in the apparently sub-luminous GRB 031203
D. Watson, S. A. Vaughan, R. Willingale +11
GRB031203 was a very low apparent luminosity gamma-ray burst (GRB). It was also the first GRB with a dust-scattered X-ray halo. The observation of the halo allowed us to infer the…
Outshining the quasars at reionisation: The X-ray spectrum and lightcurve of the redshift 6.29 Gamma-Ray Burst GRB050904
D. Watson, J. N. Reeves, J. Hjorth +7
Gamma-ray burst (GRB) 050904 is the most distant X-ray source known, at z=6.295, comparable to the farthest AGN and galaxies. Its X-ray flux decays, but not as a power-law; it is d…
Gamma-Ray Bursts observed by XMM-Newton
P. T. O'Brien, J. N. Reeves, D. Watson +2
Analysis of observations with XMM-Newton have made a significant contribution to the study of Gamma-ray Burst (GRB) X-ray afterglows. The effective area, bandpass and resolution of…
What can we learn from EPIC X-ray spectra of Seyfert 1 galaxies?
Ken Pounds, James Reeves
The EPIC detectors on XMM-Newton provide the most sensitive broad band (0.3-12 keV) X-ray spectra to date. Observations of 6 Seyfert 1 galaxies, covering a wide luminosity range, a…
Evidence for an ionised disc in the narrow-line Seyfert 1 galaxy Ark 564
S. Vaughan, K. A. Pounds, J. Reeves +2
We present simultaneous ASCA and RXTE observations of Ark 564, the brightest known ``narrow-line'' Seyfert 1 in the 2-10 keV band. The measured X-ray spectrum is dominated by a ste…
