On the braking index of the unusual high-B rotation-powered pulsar PSR J1846-0258
R. F. Archibald, V. M. Kaspi, A. P. Beardmore +2
PSR J1846-0258 is an object which straddles the boundary between magnetars and rotation powered pulsars. Though behaving for many years as a rotation-powered pulsar, in 2006, it ex…
Deep NuSTAR and Swift Monitoring Observations of the Magnetar 1E 1841-045
Hongjun An, Robert F. Archibald, Romain Hascoet +15
We report on a 350-ks NuSTAR observation of the magnetar 1E 1841-045 taken in 2013 September. During the observation, NuSTAR detected six bursts of short duration, with …
Short-period X-ray oscillations in super-soft novae and persistent SSS
J. -U. Ness, A. P. Beardmore, J. P. Osborne +10
Transient short-period <100s oscillations have been found in the X-ray light curves of three novae during their SSS phase and in one persistent SSS. We pursue an observational appr…
