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…

Generation of Correlated Time Series for X-ray Astronomy Applications

Seth Rowan Larner, Michael A. Nowak, Jörn Wilms

Cross-spectral methods have become essential for studying accretion physics in X-ray binaries and active galactic nuclei, where coherence and phase lag measurements constrain physi…

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…

Long term variability of Cygnus X-1. VIII. A spectral-timing look at low energies with NICER

Ole König, Guglielmo Mastroserio, Thomas Dauser +19

The Neutron Star Interior Composition Explorer (NICER) monitoring campaign of Cyg X-1 allows us to study its spectral-timing behavior at energies keV across all states. The…

Simultaneous fits in ISIS on the example of GRO J1008-57

Matthias Kühnel, Sebastian Müller, Ingo Kreykenbohm +9

Parallel computing and steadily increasing computation speed have led to a new tool for analyzing multiple datasets and datatypes: fitting several datasets simultaneously. With thi…
