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…
Radial velocities from Gaia BP/RP spectra
Sill Verberne, Sergey E. Koposov, Elena M. Rossi +3
The Gaia mission has provided us full astrometric solutions for over 1.5B sources. However, only the brightest 34M of those have radial velocity measurements. As a proof of concept…
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…
On measuring the Galactic dark matter halo with hypervelocity stars
O. Contigiani, E. M. Rossi, T. Marchetti
Hypervelocity stars (HVSs) travel from the Galactic Centre across the dark matter halo of the Milky Way, where they are observed with velocities in excess of the Galactic escape sp…
Gaia DR2 in 6D: Searching for the fastest stars in the Galaxy
T. Marchetti, E. M. Rossi, A. G. A. Brown
We search for the fastest stars in the subset of stars with radial velocity measurements of the second data release (DR2) of the European Space Agency mission Gaia. Starting from t…
An artificial neural network to discover Hypervelocity stars: Candidates in Gaia DR1/TGAS
T. Marchetti, E. M. Rossi, G. Kordopatis +5
The paucity of hypervelocity stars (HVSs) known to date has severely hampered their potential to investigate the stellar population of the Galactic Centre and the Galactic Potentia…
