Pulsating ultraluminous X-ray sources: modeling the thermal emission and polarization properties
S. Conforti, L. Zampieri, R. Taverna +4
Ultraluminous X-ray sources (ULXs) are enigmatic sources first discovered in the 1980s in external galaxies. They are characterized by their extraordinarily high X-ray luminosity,…
