X-ray spectral and flux variability of the microquasar GRS 1758-258 on timescales from weeks to years

Maria Hirsch, Katja Pottschmidt, David M. Smith +12

We present the spectral and timing evolution of the persistent black hole X-ray binary GRS 1758-258 based on almost 12 years of observations using the Rossi X-ray Timing Explorer P…

The giant outburst of 4U 0115+634 in 2011 with Suzaku and RXTE

Matthias Bissinger né Kühnel, Ingo Kreykenbohm, Carlo Ferrigno +19

We present an analysis of X-ray spectra of the high mass X-ray binary 4U 0115+634 as observed with Suzaku and RXTE in 2011 July, during the fading phase of a giant X-ray outburst.…

Modeling the precession of the warped inner accretion disk in the pulsars LMC X-4 and SMC X-1 with NuSTAR and XMM-Newton

McKinley C. Brumback, Ryan C. Hickox, Felix S. Fürst +3

We present a broad-band X-ray study of the effect of superorbital periods on X-ray spectra and pulse profiles in the neutron star X-ray binaries LMC X-4 and SMC X-1. These two sour…

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…

Chandra X-ray spectroscopy of the focused wind in the Cygnus X-1 system III. Dipping in the low/hard state

Maria Hirsch, Natalie Hell, Victoria Grinberg +9

We present an analysis of three Chandra High Energy Transmission Gratings observations of the black hole binary Cyg X-1/HDE 226868 at different orbital phases. The stellar wind tha…
