NuSTAR and Swift observations of the fast rotating magnetized white dwarf AE Aquarii
Takao Kitaguchi, Hongjun An, Andrei M. Beloborodov +11
AE Aquarii is a cataclysmic variable with the fastest known rotating magnetized white dwarf (P_spin = 33.08 s). Compared to many intermediate polars, AE Aquarii shows a soft X-ray…
Chandra and XMM-Newton imaging and spectroscopic study of the supernova remnant Kes 73 hosting the magnetar 1E 1841-045
Harsha S. Kumar, Samar Safi-Harb, Patrick Slane +1
We present a Chandra and XMM-Newton study of the supernova remnant (SNR) Kes 73 hosting the anomalous X-ray pulsar 1E 1841-045. The Chandra image reveals clumpy structures across t…
NuSTAR observations of magnetar 1E 1841-045
Hongjun An, Romain Hascoet, Victoria M. Kaspi +18
We report new spectral and temporal observations of the magnetar 1E 1841-045 in the Kes 73 supernova remnant obtained with the Nuclear Spectroscopic Telescope Array (NuSTAR). Combi…
High-Energy X-rays from J174545.5-285829, the Cannonball: A Candidate Pulsar Wind Nebula Associated with Sgr A East
Melania Nynka, Charles J. Hailey, Kaya Mori +12
We report the unambiguous detection of non-thermal X-ray emission up to 30 keV from the Cannonball, a few-arcsecond long diffuse X-ray feature near the Galactic Center, using the N…
X-ray Measurement of the Spin-Down of Calvera: a Radio- and Gamma-ray-Quiet Pulsar
J. P. Halpern, S. Bogdanov, E. V. Gotthelf
We measure spin-down of the 59 ms X-ray pulsar Calvera by comparing the XMM-Newton discovery data from 2009 with new Chandra timing observations taken in 2013. Its period derivativ…
X-ray Observations of Disrupted Recycled Pulsars: No Refuge for Orphaned Central Compact Objects
E. V. Gotthelf, J. P. Halpern, B. Allen +1
We present a Chandra X-ray survey of the disrupted recycled pulsars (DRPs), isolated radio pulsars with P > 20 ms and B_s < 3E10 G. These observations were motivated as a search fo…
