Accretion and Ejection Physics at High Time Resolution
F. M. Vincentelli, P. Casella, A. Veledina +18
Accretion onto compact objects is one of the most fundamental phenomena in the astrophysics, powering some of the most luminous objects in the sky. Along with this, accretion has a…
The multiple facets of millisecond pulsar binaries
A. Miraval Zanon, G. Illiano, F. Ambrosino +17
Millisecond pulsar (MSP) binaries are unique laboratories for studying matter and radiation under extreme conditions that are unattainable on Earth. Recent detections of optical mi…
How the spin-phase variability of cyclotron lines shapes the pulsed fraction spectra: insights from 4U 1538-52
Dimitrios K. Maniadakis, Ekaterina Sokolova-Lapa, Antonino D'Aì +15
We study the energy-dependent pulse profile of 4U 1538-52 and its phase-dependent spectral variability, with emphasis on the behavior around the cyclotron resonant scattering featu…
Unveiling the origin of the optical and UV emission during the 2017 giant outburst of the Galactic ULX pulsar Swift J0243.6+6124 (Corrigendum)
J. Alfonso-Garzón, J. van den Eijnden, N. P. M. Kuin +8
An error was detected in the code of one of the components considered to model the optical/UV emission of the Galactic ULX pulsar Swift J0243.6+6124 during its 2017 giant outburst.…
Disk reflection and energetics from the accreting millisecond pulsar SRGA J144459.2-604207
Christian Malacaria, Alessandro Papitto, Sergio Campana +11
Accreting millisecond pulsars (AMSPs) are excellent laboratories to study reflection spectra and their features from an accretion disk truncated by a rapidly rotating magnetosphere…
Energy-resolved pulse profile changes in V 0332+53: Indications of wings in the cyclotron absorption line profile
Antonino D'Aì, Dimitrios K. Maniadakis, Carlo Ferrigno +15
We aim to investigate the energy-resolved pulse profile changes of the accreting X-ray pulsar V 0332+53, focusing in the cyclotron line energy range, using the full set of availabl…
