Pan-chromatic observations of the remarkable nova LMC 2012
Greg J. Schwarz, Steven N. Shore, Kim L. Page +9
We present the results of an intensive multiwavelength campaign on nova LMC 2012. This nova evolved very rapidly in all observed wavelengths. The time to fall two magnitudes in the…
Repeated, Delayed Torque Variations Following X-ray Flux Enhancements in the Magnetar 1E1048.15937
R. F. Archibald, V. M. Kaspi, C. -Y. Ng +4
We report on two years of flux and spin evolution monitoring of 1E 1048.15937, a 6.5-s X-ray pulsar identified as a magnetar. Using {\it Swift} XRT data, we observed an X-ray ou…
X-ray and UV observations of V751 Cyg in an optical high state
K. L. Page, J. P. Osborne, A. P. Beardmore +3
Aims: The VY Scl system (anti-dwarf nova) V751 Cyg is examined following a claim of a super-soft spectrum in the optical low state. Methods: A serendipitous XMM-Newton X-ray observ…
The Microchannel X-ray Telescope for the Gamma-Ray Burst mission SVOM
D. Gotz, J. Osborne, B. Cordier +17
We present the Microchannel X-ray Telescope, a new light and compact focussing telescope that will be flying on the Sino-French SVOM mission dedicated to Gamma-Ray Burst science. T…
GRB 130925A: an ultra-long Gamma Ray Burst with a dust-echo afterglow, and implications for the origin of the ultra-long GRBs
P. A. Evans, R. Willingale, J. P. Osborne +24
GRB 130925A was an unusual GRB, consisting of 3 distinct episodes of high-energy emission spanning 20 ks, making it a member of the proposed category of `ultra-long' bursts.…
On the X-ray variability of magnetar 1RXS J170849.0-400910
P. Scholz, R. F. Archibald, V. M. Kaspi +4
We present a long-term X-ray flux and spectral analysis for 1RXS J170849.0-400910 using Swift/XRT spanning over 8 years from 2005-2013. We also analyze two observations from Chandr…
