Population III X-ray Binaries and their Impact on the Early Universe

Nina S. Sartorio, A. Fialkov, T. Hartwig +8

The first population of X-ray binaries (XRBs) is expected to affect the thermal and ionization states of the gas in the early Universe. Although these X-ray sources are predicted t…

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…

Metal Mixing in the R-Process Enhanced Ultra-Faint Dwarf Galaxy Reticulum II

Alexander P. Ji, Joshua D. Simon, Ian U. Roederer +9

The ultra-faint dwarf galaxy Reticulum~II was enriched by a single rare and prolific r-process event. The r-process content of Reticulum~II thus provides a unique opportunity to st…

Public Release of A-SLOTH: Ancient Stars and Local Observables by Tracing Halos

Tilman Hartwig, Mattis Magg, Li-Hsin Chen +8

The semi-analytical model A-SLOTH (Ancient Stars and Local Observables by Tracing Halos) is the first public code that connects the formation of the first stars and galaxies to obs…

Impact of the Primordial Stellar Initial Mass Function on the 21-cm Signal

T. Gessey-Jones, N. S. Sartorio, A. Fialkov +6

Properties of the first generation of stars (Pop III), such as their initial mass function (IMF), are poorly constrained by observations and have yet to converge between simulation…

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…
