Spectral and Timing Analysis of the accretion-powered pulsar 4U 1626-67 observed with Suzaku and NuSTAR
Wataru B. Iwakiri, Katja Pottschmidt, Sebastian Falkner +13
We present an analysis of the spectral shape and pulse profile of the accretion-powered pulsar 4U 1626-67 observed with Suzaku and NuSTAR during a spin-up state. The pulsar, which…

Understanding the Last Mile - Physics of the Accretion Column
Peter Kretschmar, Peter A. Becker, Dipankar Bhattacharya +17
Accreting X-ray pulsars are among the best observed objects of X-ray astronomy with a rich data set of observational phenomena in the spectral and timing domain. While the general…
