A transient ultraluminous X-ray source in NGC 55
A. Robba, C. Pinto, F. Pintore +14
Ultraluminous X-ray sources (ULXs) are a class of accreting compact objects with X-ray luminosities above 10 erg s. The average number of ULXs per galaxy is still not…
Investigating the nature of the ultraluminous X-ray sources in the galaxy NGC 925
Chiara Salvaggio, Anna Wolter, Fabio Pintore +7
Variability is a powerful tool to investigate properties of X-ray binaries (XRB), in particular for Ultraluminous X-ray sources (ULXs) that are mainly detected in the X-ray band. F…
Disk precession to explain the super-orbital modulation of LMC X-4: results from the Swift monitoring campaign
Elena Ambrosi, Antonino d'Aì, Melania del Santo +4
We studied the spectral changes of the high-mass X-ray binary system LMC X-4 to understand the origin and mechanisms beyond its super-orbital modulation (30.4 days). To this aim, w…
A multi-wavelength view of distinct accretion regimes in the pulsating ultraluminous X-ray source NGC 1313 X-2
Rajath Sathyaprakash, Timothy P. Roberts, Fabien Grisè +7
NGC 1313 X-2 is one of the few known pulsating ultraluminous X-ray sources (PULXs), and so is thought to contain a neutron star that accretes at highly super-Eddington rates. Howev…
