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…
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…
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…
The JWST Galactic Center Survey -- A White Paper
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…
TUVO-21acq: a new cataclysmic variable discovered through a UV outburst
David Modiano, Rudy Wijnands, David A. H. Buckley +3
Outbursts from cataclysmic variables, such as dwarf novae (DNe), are prevalent throughout the galaxy and are known to emit strongly in the ultraviolet (UV). However, the UV emissio…
TUVOpipe: a pipeline to search for UV transients with Swift-UVOT
David Modiano, Rudy Wijnands, Aastha Parikh +3
Despite the prevalence of transient-searching facilities operating across most wavelengths, the ultraviolet (UV) transient sky remains to be systematically studied. We have recentl…
The radial supernova remnant distribution in the Galaxy
Sill Verberne, Jacco Vink
Supernovae are the dominant source of chemical enrichment of galaxies, and they are an important source of energy to heat the interstellar medium and accelerate cosmic rays. Our kn…
First ultraviolet outburst detected from ASASSN-18eh strengthens its interpretation as a cataclysmic variable
Sill Verberne, David Modiano, Rudy Wijnands
As part of the Transient UV Objects project, we have discovered a new outburst (at the beginning of October 2020) of the candidate cataclysmic variable (CV) ASASSN-18eh using the U…
Discovery prospects of dwarf spheroidal galaxies for indirect dark matter searches
Shin'ichiro Ando, Bradley J. Kavanagh, Oscar Macias +12
We study the prospects for the Large Synoptic Survey Telescope (LSST) to find new dwarf spheroidal galaxies in the Milky Way. Adopting models of Milky-Way halo substructure and phe…
