The impact of precession on the observed population of ULXs

Norman Khan, Matthew. J. Middleton, Grzegorz Wiktorowicz +3

The discovery of neutron stars powering several ultraluminous X-ray sources (ULXs) raises important questions about the nature of the underlying population. In this paper we build…

Thermally driven winds in ULXs

Matthew Middleton, Nick Higginbottom, Christian Knigge +2

The presence of radiatively driven outflows is well established in ultraluminous X-ray sources (ULXs). These outflows are optically thick and can reprocess a significant fraction o…

Predicting the self-lensing population in optical surveys

Grzegorz Wiktorowicz, Matthew Middleton, Norman Khan +3

The vast majority of binaries containing a compact object and a regular star spend most of their time in a quiescent state where no strong interactions occur between components. De…

Wind-powered ultraluminous X-ray sources

Grzegorz Wiktorowicz, Jean-Pierre Lasota, Krzysztof Belczynski +3

Although ultra-luminous X-ray sources (ULX) are important for astrophysics due to their extreme apparent super-Eddington luminosities, their nature is still poorly known. Theoretic…

Non-interacting black hole binaries with Gaia and LAMOST

Grzegorz Wiktorowicz, Youjun Lu, Łukasz Wyrzykowski +4

Until recently, black holes (BHs) could be discovered only through accretion from other stars in X-ray binaries, or in merging double compact objects. Improvements in astrometric a…

The connection between merging double compact objects and the Ultraluminous X-ray Sources

Samaresh Mondal, Krzysztof Belczyński, Grzegorz Wiktorowicz +2

We explore the different formation channels of merging double compact objects (DCOs: BH-BH/BH-NS/NS-NS) that went through a ultraluminous X-ray phase (ULX: X-ray sources with appar…
