A-SLOTH: Ancient Stars and Local Observables by Tracing Halos
Mattis Magg, Tilman Hartwig, Li-Hsin Chen +1
Galaxies are thought to reside inside of large gravitationally bound structures of dark matter, so-called haloes. While the smallest of these haloes host no or only a few stars, th…
Tracing stars in Milky Way satellites with A-SLOTH
Li-Hsin Chen, Mattis Magg, Tilman Hartwig +3
We study the stellar mass-to-halo mass relation at in 30 Milky Way-like systems down to the ultra-faint () regime using the semi-analytic model A-SLOTH. A…
Gravitational waves from the remnants of the first stars in nuclear star clusters
Boyuan Liu, Volker Bromm
We study Population III (Pop III) binary remnant mergers in nuclear star clusters (NSCs) with a semi-analytical approach for early structure formation. Within this framework, we ke…
Origin of metals in old Milky Way halo stars based on GALAH and Gaia
Miho N. Ishigaki, Tilman Hartwig, Yuta Tarumi +6
Stellar and supernova nucleosynthesis in the first few billion years of the cosmic history have set the scene for early structure formation in the Universe, while little is known a…
Metal-Poor Stars Observed with the Southern African Large Telescope
Kaitlin C. Rasmussen, Joseph Zepeda, Timothy C. Beers +5
We present the first release of a large-scale study of relatively bright (V < 13.5) metal-poor stars observed with the Southern African Large Telescope (SALT), based on high-resolu…
Dual supermassive black holes at close separation revealed by the Hyper Suprime-Cam Subaru Strategic Program
John D. Silverman, Shenli Tang, Khee-Gan Lee +30
The unique combination of superb spatial resolution, wide-area coverage, and deep depth of the optical imaging from the Hyper Suprime-Cam (HSC) Subaru Strategic Program is utilized…
