The X-ray emission of the long-period transient and accreting cataclysmic variable ASKAP J174508.9-505149

M. Imbrogno, M. Veresvarska, Y. L. Wang +8

Long-period transients (LPTs) challenge our knowledge of the mechanism producing radio periodic pulsations in compact objects. Some LPTs have been associated with systems hosting a…

A candidate proton cyclotron feature in the ultraluminous X-ray source NGC 4656 ULX-1

Nelson Cruz-Sanchez, Enzo A. Saavedra, Federico A. Fogantini +6

Ultraluminous X-ray sources represent extreme super-Eddington accretion regimes, and a subset is now known to host highly magnetized neutron stars. However, direct observational pr…

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…
