Discovery of Galactic center ejected star in DESI DR1
Manuel Cavieres, Sergey E. Koposov, Elena Maria Rossi +2
Hypervelocity stars (HVSs) are stars ejected from the Galactic Centre (GC) through tidal interactions with the central supermassive black hole. Formed in the immediate vicinity of…

Rainer Schoedel, Steve Longmore, Jonny Henshaw +111
The inner hundred parsecs of the Milky Way hosts the nearest supermassive black hole, largest reservoir of dense gas, greatest stellar density, hundreds of massive main and post ma…
Searching for stars ejected from the Galactic Centre in DESI
Sill Verberne, Sergey E. Koposov, Elena Maria Rossi +1
Dynamical interactions between stars and the super massive black hole Sgr A* at the Galactic Centre (GC) may eject stars into the Galactic halo. While recent fast ejections by Sgr…
Double progenitor origin of the S-star cluster
Sill Verberne, Elena Maria Rossi, Sergey E. Koposov +3
The origin of the cluster of S-stars located in the Galactic Centre is tied to the supermassive black hole Sagittarius A*, but exactly how is still debated. In this paper, we inves…
