Pebbles to Gems: Intermediate-mass black holes in the first star clusters

Benedetta Mestichelli, Manuel Arca Sedda, Marta Volonteri +9

The rapid assembly of supermassive black holes (SMBHs) observed at requires efficient seeding mechanisms in the early Universe. Population III (Pop. III) star clusters…

Mass distribution of Pop III star clusters: A-SLOTH predictions for JWST observability

Veronika Lipatova, Simon C. O. Glover, Ralf S. Klessen +1

This study aims to model the expected luminosities of the first four Balmer-series transitions from Pop.\,III star-forming halos and assess their detectability with JWST/NIRSpec ac…

Impact of initial mass function on the chemical evolution of high-redshift galaxies

Boyuan Liu, Michela Mapelli, Volker Bromm +10

Recent observations by the James Webb Space Telescope (JWST) have found evidence for an invariant relation between stellar mass, metallicity, and star formation rate up to $z\sim 8…

Black Hole - Neutron Star and Binary Neutron Star Mergers from Population III and II stars

Benedetta Mestichelli, Michela Mapelli, Filippo Santoliquido +9

Population III (Pop.III) stars are expected to be massive and to undergo minimal mass loss due to their lack of metals, making them ideal progenitors of black holes and neutron…

M3DIS -- A grid of 3D radiation-hydrodynamics stellar atmosphere models for stellar surveys. II. Carbon-enhanced metal-poor stars

Philipp Eitner, Maria Bergemann, Richard Hoppe +6

Understanding the origin and evolution of carbon-enhanced metal-poor (CEMP) stars is key to tracing the Galaxy's early chemical enrichment. We investigate how realistic 3D radiatio…

A-SLOTH reveals the nature of the first stars

Tilman Hartwig, Veronika Lipatova, Simon C. O. Glover +1

The first generation of stars (PopIII) are too dim to be observed directly and probably too short-lived to have survived for local observations. Hence, we rely on simulations and i…
