The ejection and detectability of high- and hyper-velocity stars by compact object binaries in globular clusters
Fraser A. Evans, Steffani M. Grondin, Claire S. Ye +3
The dense cores of Milky Way globular clusters (GCs) play host to a variety of dynamical encounters between stellar objects, which can accelerate stars to velocities high enough to…
The impact of the Galactic bar and the Large Magellanic Cloud on hypervelocity star trajectories
Isabella Armstrong, Fraser A. Evans, Jo Bovy
Hypervelocity stars (HVSs) ejected from the Galactic Center (GC) at speeds faster than the Galactic escape velocity are useful tools to provide insight into the Milky Way's dark ma…
Improved constraints on Galactic Centre ejection of hypervelocity stars based on novel search method
Sill Verberne, Elena Maria Rossi, Sergey E. Koposov +6
Hypervelocity stars (HVSs) are stars which have been ejected from the Galactic Centre (GC) at velocities of up to a few thousand km/s. They are tracers of the Galactic potential an…
Constraints on the Galactic Centre environment from \textit{Gaia} hypervelocity stars III: Insights on a possible companion to Sgr A*
Fraser A. Evans, Alexander Rasskazov, Amber Remmelzwaal +4
We consider a scenario in which Sgr A* is in a massive black hole binary (MBHB) with an as-of-yet undetected supermassive or intermediate-mass black hole companion. Dynamical encou…
Comparing hypervelocity star populations from the Large Magellanic Cloud and the Milky Way
Fraser A. Evans, Tommaso Marchetti, Elena Maria Rossi +2
We predict and compare the distributions and properties of hyper-velocity stars (HVSs) ejected from the centres of the Milky Way (MW) and the Large Magellanic Cloud (LMC). In our m…
Red Misfits in the Sloan Digital Sky Survey: Properties of Star-forming Red Galaxies
Fraser A. Evans, Laura C. Parker, Ian D. Roberts
We study Red Misfits, a population of red, star-forming galaxies in the local Universe. We classify galaxies based on inclination-corrected optical colours and specific star format…
