Swift multi-wavelength observations of the bright flaring burst GRB051117A
M. R. Goad, K. L. Page, O. Godet +13
We report on the temporal and spectral characteristics of the early X-ray emission from the Gamma Ray Burst 051117A as observed by Swift. The superb quality of the early X-ray ligh…
Chandra monitoring observations of the ultraluminous X-ray source NGC 5204 X-1
T. P. Roberts, R. E. Kilgard, R. S. Warwick +2
We report the results of a 2-month campaign conducted with the Chandra X-ray observatory to monitor the ultraluminous X-ray source (ULX) NGC 5204 X-1. This was composed of a 50-ks…
An XMM-Newton view of M101 - II. Global X-ray source properties
L. P. Jenkins, T. P. Roberts, R. S. Warwick +2
We present the global X-ray properties of the point source population in the grand-design spiral galaxy M101, as seen with XMM-Newton. 108 X-ray sources are detected within the D25…
XMM-Newton observations of high-luminosity radio-quiet QSOs
K. L. Page, J. N. Reeves, P. T. O'Brien +2
XMM Newton observations of five high-luminosity radio-quiet QSOs (Q 0144-3938, UM 269, PG 1634+706, SBS 0909+532 and PG 1247+267) are presented. Spectral energy distributions were…
Variability in black hole accretion discs
A. R. King, J. E. Pringle, R. G. West +1
Observations of accreting systems often show significant variability (10-20 percent of accretion luminosity) on timescales much longer than expected for the disc regions releasing…
An X-ray Baldwin effect for the narrow Fe K-alpha lines observed in Active Galactic Nuclei
K. L. Page, P. T. O'Brien, J. N. Reeves +1
The majority of Active Galactic Nuclei (AGN) observed by XMM-Newton reveal narrow Fe K-alpha lines at ~ 6.4 keV, due to emission from cold (neutral) material. There is an X-ray Bal…
