Hypervelocity Stars from a Supermassive Black Hole-Intermediate-mass Black Hole binary
Alexander Rasskazov, Giacomo Fragione, Nathan W. C. Leigh +4
In this paper we consider a scenario where the currently observed hypervelocity stars in our Galaxy have been ejected from the Galactic center as a result of dynamical interactions…
Metallicity dependence of the Hercules stream in Gaia/RAVE data -- explanation by non-closed orbits
Kohei Hattori, Naoteru Gouda, Taihei Yano +4
The origin of the Hercules stream, the most prominent velocity substructure in the Solar neighbour disc stars, is still under debate. Recent accurate measurements of position, velo…
Merger of multiple accreting black holes concordant with gravitational wave events
Hiromichi Tagawa, Masayuki Umemura
Recently, advanced Laser Interferometer Gravitational-Wave Observatory (aLIGO) has detected black hole (BH) merger events, most of which are sourced by BHs more massive than $30~M_…
Compact object mergers driven by gas fallback
Hiromichi Tagawa, Takayuki R. Saitoh, Bence Kocsis
Recently several gravitational wave detections have shown evidence for compact object mergers. However, the astrophysical origin of merging binaries is not well understood. Stellar…
