Outbursts of the intermediate-mass black hole HLX-1: a wind instability scenario
Roberto Soria, Aina Musaeva, Kinwah Wu +5
We model the intermediate-mass black hole HLX-1, using the Hubble Space Telescope, XMM-Newton and Swift. We quantify the relative contributions of a bluer component, function of X-…

Stellar winds near massive black holes: The case of the S-stars
Nora Lützgendorf, Edwin van der Helm, Inti Pelupessy +1
The Galactic center provides a unique laboratory to study the interaction of a supermassive black hole (SMBH) with its gaseous and stellar environment. Simulations to determine the…

Simulations of the tidal interaction and mass transfer of a star in an eccentric orbit around an intermediate-mass black hole: the case of HLX-1
Edwin van der Helm, Simon Portegies Zwart, Onno Pols
The X-ray source HLX-1 near the spiral galaxy ESO 243-49 is currently the best intermediate-mass black hole candidate. It has a peak bolometric luminosity of erg s…
