Populations of highly variable X-ray sources in the XMMNewton slew survey
Dongyue Li, R. L. C. Starling, R. D. Saxton +2
We present the identifications of a flux-limited sample of highly variable X-ray sources on long time-scales from the second catalogue of the XMMNewton SLew survey (XMMSL2). The…
Highly variable AGN from the XMM-Newton Slew Survey
N. L. Strotjohann, R. D. Saxton, R. L. C. Starling +4
We investigate the properties of a variability-selected complete sample of AGN in order to identify the mechanisms which cause large amplitude X-ray variability on time scales of y…
The story of Seyfert galaxy RE J2248-511: from intriguingly ultrasoft to unremarkably average
Rhaana Starling, C. Done, C. Jin +7
RE J2248-511 is one of only 14 non-blazar AGN detected in the far ultraviolet by the ROSAT Wide Field Camera implying a large ultrasoft X-ray flux. This soft X-ray excess is strong…
Swift follow-up of unidentified X-ray sources in the XMM-Newton Slew Survey
R. L. C. Starling, P. A. Evans, A. M. Read +8
We present deep Swift follow-up observations of a sample of 94 unidentified X-ray sources from the XMM-Newton Slew Survey. The X-ray Telescope on-board Swift detected 29% of the sa…
Swift observations of the X-ray and UV evolution of V2491 Cyg (Nova Cyg 2008 No. 2)
K. L. Page, J. P. Osborne, P. A. Evans +8
We present extensive, high-density Swift observations of V2491 Cyg (Nova Cyg 2008 No. 2). Observing the X-ray emission from only one day after the nova discovery, the source is fol…
Multi-wavelength observations of the energetic GRB 080810: detailed mapping of the broadband spectral evolution
K. L. Page, R. Willingale, E. Bissaldi +31
GRB 080810 was one of the first bursts to trigger both Swift and the Fermi Gamma-ray Space Telescope. It was subsequently monitored over the X-ray and UV/optical bands by Swift, in…
Testing the blast wave model with Swift GRBs
P. A. Curran, R. L. C. Starling, A. J. van der Horst +1
The complex structure of the light curves of Swift GRBs has made the identification of breaks, and the interpretation of the blast wave caused by the burst, more difficult than in…
Constraining the energy budget of GRB 080721
R. L. C. Starling, E. Rol, A. J. van der Horst +17
We follow the bright, highly energetic afterglow of Swift-discovered GRB 080721 at z=2.591 out to 36 days or 3e6 s since the trigger in the optical and X-ray bands. We do not detec…
On the nature of late X-ray flares in Swift Gamma-ray Bursts
P. A. Curran, R. L. C. Starling, P. T. O'Brien +3
Previously detected in only a few gamma-ray bursts (GRBs), X-ray flares are now observed in ~50% of Swift GRBs, though their origins remain unclear. Most flares are seen early on i…
GRB060602B = Swift J1749.4-2807: an unusual transiently accreting neutron-star X-ray binary
Rudy Wijnands, Evert Rol, Ed M. Cackett +2
We present an analysis of the Swift BAT and XRT data of GRB060602B, which is most likely an accreting neutron star in a binary system and not a gamma-ray burst. Our analysis shows…
