Intermediate polars in the Swift/BAT survey: Spectra and white dwarf masses (2009)
Brunschweiger, Jorg, Greiner, Jochen, Ajello, Marco, Osborne, Julian
White dwarf masses in cataclysmic variables are difficult to determine accurately, but are fundamental for understanding binary system parameters, as well as binary evolution. We investigate the...
Redshift Filtering by Swift Apparent X-ray Column Density (2006)
Grupe, Dirk, Nousek, John A., Berk, Daniel E. Vanden, Roming, Peter W. A., Burrows, David N., Godet, Olivier, ...
We remark on the utility of an observational relation between the absorption column density in excess of the Galactic absorption column density, $\Delta N_{\rm H} = N_{\rm H, fit} - N_{\rm H, gal}$,...
Grupe, Dirk, Gronwall, Caryl, Wang, Xiang-Yu, Roming, Peter, Cummings, Jay, Zhang, Bing, ...
We report the results of the Swift and XMM observations of the Swift-discovered long Gamma-Ray Burst GRB 060729 ($T_{90}$=115s). The afterglow of this burst was exceptionally bright in X-rays as well...
Swift Observations of GRB 050603: An afterglow with a steep late time decay slope (2006)
Grupe, Dirk, Brown, Peter, Cummings, Jay, Zhang, Bing, Retter, Alon, Burrows, David N., ...
We report the results of Swift observations of the Gamma Ray Burst GRB 050603. With a V magnitude V=18.2 about 10 hours after the burst the optical afterglow was the brightest so far detected by...
Gamma-ray bursts: Restarting the Engine (2005)
King, Andrew, O'Brien, Paul T., Goad, Michael R., Osborne, Julian, Olsson, Emma, Page, Kim
Recent gamma-ray burst observations have revealed late-time, highly energetic events which deviate from the simplest expectations of the standard fireball picture. Instead they may indicate that the...
First XMM-Newton observations of a cataclysmic variable II: the X-ray spectrum of OY Car (2000)
Ramsay, Gavin, Cordova, France, Cottam, Jean, Mason, Keith, Much, Rudi, Osborne, Julian, ...
We present XMM-Newton X-ray spectra of the disc accreting cataclysmic variable OY Car, which were obtained during the performance verification phase of the mission. These data were taken 4 days after...
First XMM-Newton observations of a Cataclysmic Variable I: Timing studies of OY Car (2000)
Ramsay, Gavin, Poole, Tracey, Mason, Keith, Cordova, France, Priedhorsky, William, Breeveld, Alice, ...
We present XMM-Newton observations of the eclipsing, disc accreting, cataclysmic variable OY Car which were obtained as part of the performance verification phase of the mission. The star was...
