Weighing the Darkness II: Astrometric Measurement of Partial Orbits with Gaia
Jeff J. Andrews, Katelyn Breivik, Chirag Chawla +2
Over the course of several years, stars trace helical trajectories as they traverse across the sky due to the combined effects of proper motion and parallax. It is well known that…
A Young, Low-Density Stellar Stream in the Milky Way Disk: Theia 456
Jeff J. Andrews, Jason L. Curtis, Julio Chanamé +4
Our view of the variety of stellar structures pervading the local Milky Way has been transformed by the application of clustering algorithms to the Gaia catalog. In particular, sev…
Gaia May Detect Hundreds of Well-characterised Stellar Black Holes
Chirag Chawla, Sourav Chatterjee, Katelyn Breivik +3
Detection of black holes (BHs) with detached luminous companions (LCs) can be instrumental in connecting the BH properties with their progenitors' since the latter can be inferred…
Combining Astrometry and Elemental Abundances: The Case of the Candidate Pre-Gaia Halo Moving Groups G03-37, G18-39, and G21-22
S. C. Schuler, J. J. Andrews, V. R. Clanzy +3
While most moving groups are young and nearby, a small number have been identified in the Galactic halo. Understanding the origin and evolution of these groups is an important piec…
The Heraklion Extragalactic Catalogue (HECATE): a value-added galaxy catalogue for multi-messenger astrophysics
Konstantinos Kovlakas, Andreas Zezas, Jeff J. Andrews +6
We present the Heraklion Extragalactic Catalogue, or HECATE, an all-sky value-added galaxy catalogue, aiming to facilitate present and future multi-wavelength and multi-messenger s…
Probing the progenitors of spinning binary black-hole mergers with long gamma-ray bursts
Simone S. Bavera, Tassos Fragos, Emmanouil Zapartas +15
Long-duration gamma-ray bursts are thought to be associated with the core-collapse of massive, rapidly spinning stars and the formation of black holes. However, efficient angular m…
Revisiting the explodability of single massive star progenitors of stripped-envelope supernovae
E. Zapartas, M. Renzo, T. Fragos +12
Stripped-envelope supernovae (Types IIb, Ib, and Ic) that show little or no hydrogen comprise roughly one-third of the observed explosions of massive stars. Their origin and the ev…
The hydrodynamic evolution of binary black holes embedded within the vertically stratified disks of active galactic nuclei
Nicholas Kaaz, Sophie Lund Schrøder, Jeff J. Andrews +2
Stellar-mass black holes can become embedded within the gaseous disks of active galactic nuclei (AGNs). Afterwards, their interactions are mediated by their gaseous surroundings. I…
