On the Detection of Supermassive Primordial Stars
Marco Surace, Daniel J. Whalen, Tilman Hartwig +6
The collapse of supermassive primordial stars in hot, atomically-cooled halos may have given birth to the first quasars at 15 - 20. Recent numerical simulations of these r…
Fingerprint of the first stars: multi-enriched extremely metal-poor stars in the TOPoS survey
Tilman Hartwig, Miho N. Ishigaki, Ralf S. Klessen +1
Extremely metal poor (EMP) stars in the Milky Way inherited the chemical composition of the gas out of which they formed. They therefore carry the chemical fingerprint of the first…
Titans of the Early Universe: The Prato Statement on the Origin of the First Supermassive Black Holes
Tyrone E. Woods, Bhaskar Agarwal, Volker Bromm +30
In recent years, the discovery of massive quasars at z~7 has provided a striking challenge to our understanding of the origin and growth of supermassive black holes in the early Un…
Statistical predictions for the first black holes
Tilman Hartwig
The recent observations of supermassive black holes (SMBHs) at high redshift challenge our understanding of their formation and growth. There are different proposed pathways to for…
Gravitational Wave Signals from the First Massive Black Hole Seeds
Tilman Hartwig, Bhaskar Agarwal, John A. Regan
Recent numerical simulations reveal that the isothermal collapse of pristine gas in atomic cooling haloes may result in stellar binaries of supermassive stars with $M_* \gtrsim 10^…
Descendants of the first stars: the distinct chemical signature of second generation stars
Tilman Hartwig, Naoki Yoshida, Mattis Magg +9
Extremely metal-poor (EMP) stars in the Milky Way (MW) allow us to infer the properties of their progenitors by comparing their chemical composition to the metal yields of the firs…
