Preferential accretion onto eccentric and unequal binary black holes
Stanislav DeLaurentiis, Zoltán Haiman, Magdalena Siwek
Supermassive binary black holes (SMBBHs) are expected to be surrounded by circumbinary disks (CBDs) which affect the binary through gravitational forces and accretion. It has been…
\texttt{calypso}: a Parameter-Conditioned Stochastic Surrogate Model for Circumbinary Accretion Time-Series
Magdalena Siwek, Matt Ho, Earl Bellinger
We present calypso, a parameter-conditioned stochastic surrogate model for circumbinary accretion flows. We represent the total and individual accretion time series in a PCA basis…
Observational limits on the X-ray emission from the bubble nebula surrounding Ho IX X-1
Rajath Sathyaprakash, Timothy P. Roberts, Magdalena M. Siwek
Optical and radio observations of shock-ionised bubble nebulae surrounding ultraluminous X-ray sources (ULXs) suggest that they are powered by jets or super-critical outflows presu…
Optical and X-ray luminosity of expanding nebulae around ultraluminous X-ray sources
Magdalena Siwek, Aleksander Sadowski, Ramesh Narayan +2
We have performed a set of simulations of expanding, spherically symmetric nebulae inflated by winds from accreting black holes in ultraluminous X-ray sources (ULXs). We implemente…
