No anti-correlation between cyclotron line energy and X-ray flux in 4U 0115+634
Sebastian Müller, Carlo Ferrigno, Matthias Kühnel +18
We report on an outburst of the high mass X-ray binary 4U 0115+63 with a pulse period of 3.6s in 2008 March/April as observed with RXTE and INTEGRAL. During the outburst the neutro…
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…
The reawakening of the sleeping X-ray pulsar XTE J1946+274
Sebastian Müller, Matthias Kühnel, Isabel Caballero +9
We report on a series of outbursts of the high mass X-ray binary XTE J1946+274 in 2010/2011 as observed with INTEGRAL, RXTE, and Swift. We discuss possible mechanisms resulting in…
X-ray pulsars: a review
I. Caballero, J. Wilms
Accreting X-ray pulsars are among the most luminous objects in the X-ray sky. In highly magnetized neutron stars (B~10^12 G), the flow of matter is dominated by the strong magnetic…
Outburst of GX 304-1 monitored with INTEGRAL: positive correlation between the cyclotron line energy and flux
D. Klochkov, V. Doroshenko, A. Santangelo +10
X-ray spectra of many accreting pulsars exhibit significant variations as a function of flux and thus of mass accretion rate. In some of these pulsars, the centroid energy of the c…
The relative and absolute timing accuracy of the EPIC-pn camera on XMM-Newton, from X-ray pulsations of the Crab and other pulsars
A. Martin-Carrillo, M. G. F. Kirsch, I. Caballero +13
Reliable timing calibration is essential for the accurate comparison of XMM-Newton light curves with those from other observatories, to ultimately use them to derive precise physic…
