Multi-wavelength spectroscopic analysis of the ULX Holmberg II X-1 and its nebula suggests the presence of a heavy black hole accreting from a B-type donor
S. Reyero Serantes, L. Oskinova, W. -R. Hamann +11
Ultra-luminous X-ray sources (ULXs) are high-mass X-ray binaries with an X-ray luminosity above erg s. These ULXs can be powered by black holes that are more massi…
Exploring the case for hard-X-ray beaming in NGC 6946 X-1
Tobias Beuchert, Matthew J. Middleton, Roberto Soria +5
In order to understand the nature of super-Eddington accretion we must explore both the emission emerging directly from the inflow and its impact on the surroundings. In this paper…
Einstein Probe discovery of EP J005245.1-722843: a rare BeWD binary in the Small Magellanic Cloud?
A. Marino, H. Yang, F. Coti Zelati +32
On May 27 2024, the Wide-field X-ray Telescope onboard the Einstein Probe (EP) mission detected enhanced X-ray emission from a new transient source in the Small Magellanic Cloud (S…
Absence of nebular He{\sc ii} 4686 constrains the UV emission from the Ultraluminous X-ray pulsar NGC~1313~X--2
Andrés Gúrpide, Noel Castro Segura, Roberto Soria +1
While much has been learned in recent decades about the X-ray emission of the extragalactic Ultraluminous X-ray sources (ULXs), their radiative output in the UV band remains poorly…
