Fingerprints of thermal Comptonization in accreting neutron stars. Plasma-vacuum interplay in cyclotron lines and polarisation
E. Sokolova-Lapa, D. K. Maniadakis, J. J. R. Stierhof +11
X-ray emission from accreting, strongly magnetised neutron stars and its pulse-phase variability probe their magnetic-field geometry, spin orientation, and emission processes. Whet…
Pulse profiles of accreting neutron stars - A review of analysis methods, observations, and theoretical models
Katja Pottschmidt, Peter Kretschmar, Ekaterina Sokolova-Lapa +25
X-ray pulsars are highly magnetized ( G) neutron stars accreting from a donor star. Their characteristic X-ray emission arises from accreted material decelerated fro…
Energy-resolved pulse profiles of Vela X-1: cross-calibrating XMM-Newton and NuSTAR to trace spectral features
Dimitrios K. Maniadakis, Antonino D'Aì, Camille M. Diez +12
Pulse profiles probe the emission geometry of accreting X-ray pulsars, but their observed shapes may depend on instrumental response and observational setup. The pulsed fraction sp…
Flux variability of the "10 keV feature" of 4U 0115+63
Katrin Berger, Ekaterina Sokolova-Lapa, Ralf Ballhausen +14
X-ray spectra of accretion-powered X-ray pulsars can often be described using a power-law continuum with a high-energy cutoff, which might be further modified by additional spectra…
The elusive cyclotron line in 4U 1901+03: hidden, yet present
Elena Ambrosi, Antonino D' Aì, Giancarlo Cusumano +8
Context. Cyclotron resonant scattering features (CRSFs) in accreting X-ray pulsars are often difficult to detect, especially when shallow or variable. Recent studies have shown tha…
Unprecedentedly bright X-ray flaring in Cygnus X-1 observed by INTEGRAL
P. Thalhammer, T. Bouchet, J. Rodriguez +15
We study three extraordinarily bright X-ray flares originating from Cyg X-1 seen on 2023 July 10 detected with INTEGRAL. The flares had a duration on the order of only ten minutes…
