Pulsating ULXs: large pulsed fraction excludes strong beaming
Alexander A. Mushtukov, Simon Portegies Zwart, Sergey S. Tsygankov +2
The recent discovery of pulsating ultra-luminous X-ray sources (ULXs) shows that the apparent luminosity of accreting neutron stars (NSs) can exceed the Eddington luminosity by a f…
Electron-positron pairs in hot plasma of accretion column in bright X-ray pulsars
Alexander A. Mushtukov, Igor S. Ognev, Dmitrij I. Nagirner
The luminosity of X-ray pulsars powered by accretion onto magnetized neutron stars covers a wide range over a few orders of magnitude. The brightest X-ray pulsars recently discover…
Properties of the transient X-ray pulsar Swift J1816.7--1613 and its optical companion
Armin Nabizadeh, Sergey S. Tsygankov, Dmitrij I. Karasev +4
We present results of investigation of the poorly studied X-ray pulsar Swift J1816.7--1613 during its transition from the type I outburst to the quiescent state. Our studies are ba…
Timing properties of ULX pulsars: optically thick envelopes and outflows
Alexander A. Mushtukov, Adam Ingram, Matthew Middleton +2
It has recently been discovered that a fraction of ultra-luminous X-ray sources (ULXs) exhibit X-ray pulsations, and are therefore powered by super-Eddington accretion onto magneti…
Basic geometric and kinematic features of the Standard Cosmological Model
D. I. Nagirner, S. G. Jorstad, A. V. Dementyev
We present a brief history of the construction of models of the universe, followed by calculations of quantitative characteristics of basic geometric and kinematic properties of th…
Compton scattering S-matrix and cross section in strong magnetic field
Alexander A. Mushtukov, Dmitrij I. Nagirner, Juri Poutanen
Compton scattering of polarized radiation in a strong magnetic field is considered. The recipe for calculation of the scattering matrix elements, the differential and total cross s…
