Where are the extremely metal-poor stars in the Milky Way and Andromeda? Expectations from TNG50
Li-Hsin Chen, Annalisa Pillepich, Simon C. O. Glover +1
We analyse the location of extremely metal-poor stars (EMPs, [Fe/H]) in 198 Milky Way (MW)/M31-like galaxies at in the TNG50 simulation. Each system is divided into fo…
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…
Comparing simulated Milky Way satellite galaxies with observations using unsupervised clustering
Li-Hsin Chen, Tilman Hartwig, Ralf S. Klessen +1
We develop a new analysis method that allows us to compare multi-dimensional observables to a theoretical model. The method is based on unsupervised clustering algorithms which ass…
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…
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…
Effect of the cosmological transition to metal-enriched star-formation on the hydrogen 21-cm signal
Mattis Magg, Itamar Reis, Anastasia Fialkov +6
Mapping Cosmic Dawn with 21-cm tomography offers an exciting new window into the era of primordial star formation. However, self-consistent implementation of both the process of st…
