Swift observations of two outbursts from the magnetar 4U 0142+61
R. F. Archibald, V. M. Kaspi, P. Scholz +3
4U 0142+61 is one of a small class of persistently bright magnetars. Here we report on a monitoring campaign of 4U 0142+61 from 2011 July 26 - 2016 June 12 using the Swift X-ray Te…
A Magnetar-like Outburst from a High-B Radio Pulsar
R. F. Archibald, V. M. Kaspi, S. P. Tendulkar +1
Radio pulsars are believed to have their emission powered by the loss of rotational kinetic energy. By contrast, magnetars show intense X-ray and gamma-ray radiation whose luminosi…
Green Bank Telescope and Swift X-ray Telescope Observations of the Galactic Center Radio Magnetar SGR J1745-2900
Ryan S. Lynch, Robert F. Archibald, Victoria M. Kaspi +1
We present results from eight months of Green Bank Telescope 8.7-GHz observations and nearly 18 months Swift X-ray telescope observations of the radio magnetar SGR J1745-2900, whic…
NuSTAR observations of X-ray bursts from the magnetar 1E 1048.1-5937
Hongjun An, Victoria M. Kaspi, Andrei M. Beloborodov +13
We report the detection of eight bright X-ray bursts from the 6.5-s magnetar 1E 1048.1-5937, during a 2013 July observation campaign with the Nuclear Spectroscopic Telescope Array…
Timing and Flux Evolution of the Galactic Center Magnetar SGR J1745-2900
V. M. Kaspi, R. F. Archibald, V. Bhalerao +19
We present the X-ray timing and spectral evolution of the Galactic Center magnetar SGR J1745-2900 for the first ~4 months post-discovery using data obtained with the Nuclear Spectr…
