Super-Eddington Accretion through a Multiwavelength Lens: Searching for Counterparts of Ultraluminous X-ray Sources
R. Amato, M. Bachetti, R. Soria +8
Ultraluminous X-ray sources (ULXs) represent the closest and most accessible laboratories to study sustained super-Eddington accretion onto compact objects. Over the past decade, t…
Double-hump spectrum, pulse profile dip, and pulsed fraction spectra from the low-accretion regime in the X-ray pulsar MAXI J0655-013
C. Malacaria, S. N. Pike, A. D'Aì +18
Accreting X-ray pulsars (XRPs) undergo different physical regimes depending on the mass accretion rate. Recent observations have shown a dramatic change in the emission properties…
First look at Vela X-1 with XRISM: A simultaneous campaign with XMM-Newton and NuSTAR
C. M. Diez, S. Dupourqué, M. Zhou +6
High-Mass X-ray Binaries (HMXBs) serve as useful laboratories for exploring the behaviour of accreted matter onto compact objects and for probing the complex wind environments of m…
Wobbling around the clock: magnetically-driven quasi-periodic oscillations in pulsating ultraluminous X-ray sources
M. Veresvarska, M. Imbrogno, R. Amato +8
Ultraluminous X-ray sources (ULXs) are X-ray binary systems containing an accreting neutron star (NS) or black hole emitting at luminosities above the Eddington limit of a $10M_{\o…
Variable structures in the stellar wind of the HMXB Vela X-1
L. Abalo, P. Kretschmar, F. Fürst +9
Strong stellar winds are an important feature in wind-accreting high-mass X-ray binary (HMXB) systems, providing insights into stellar evolution and their impact on surrounding env…
