Cyclotron lines in subcritical X-ray pulsars: Monte Carlo simulations reveal the origin of the observed variability
Prodromos Fotiadis, Nick Loudas, Nikolaos D. Kylafis +1
Observed cyclotron resonant scattering features (CRSFs) in X-ray pulsars (XRPs) exhibit strong variability. In the subcritical luminosity regime, the centroid energy () a…
A quantitative explanation of the cyclotron-line variation in accreting magnetic neutron stars of super-critical luminosity
Nick Loudas, Nikolaos D. Kylafis, Joachim E. Trümper
Magnetic neutron stars (NSs) often exhibit a cyclotron resonant scattering feature (CRSF) in their X-ray spectra. Cyclotron lines are believed to form in the radiative shock in the…
Cyclotron line formation by reflection on the surface of a magnetic neutron star
N. D. Kylafis, J. E. Trümper, N. A. Loudas
Accretion onto magnetic neutron stars results in X-ray spectra that often exhibit a cyclotron resonance scattering feature (CRSF) and, sometimes, higher harmonics of it. Two places…
The extended Northern ROSAT Galaxy Cluster Survey (NORAS II) I. Survey Construction and First Results
Hans Boehringer, Gayoung Chon, Joerg Retzlaff +3
As the largest, clearly defined building blocks of our Universe, galaxy clusters are interesting astrophysical laboratories and important probes for cosmology. X-ray surveys for ga…
Second ROSAT all-sky survey (2RXS) source catalogue
Th. Boller, M. J. Freyberg, J. Truemper +3
We present the second ROSAT all-sky survey source catalogue, hereafter referred to as the 2RXS catalogue. This is the second publicly released ROSAT catalogue of point-like sources…
