Unveiling the disc structure in ultraluminous X-ray source NGC 55 ULX-1
F. Barra, C. Pinto, D. J. Walton +11
Despite two decades of studies, it is still not clear whether ULX spectral transitions are due to stochastic variability in the wind or variations in the accretion rate or in the s…

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…
