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…

Optimal neighbourhood to nurture giants: a fundamental link between star forming galaxies and direct collapse black holes

Bhaskar Agarwal, Fergus Cullen, Sadegh Khochfar +2

Massive black hole seeds resulting from the \textit{direct} collapse of pristine gas require a metal-free atomic cooling halo with extremely low H frac…

Primordial Gas Collapse in The Presence of Radiation: Direct Collapse Black Hole or Population III star?

Bhaskar Agarwal

The first billion years in the evolution of the Universe mark the formation of the first stars, black holes and galaxies. The radiation from the first galaxies plays an important r…

Nature and chemical abundances of a sample of Lyman- emitter objects at high redshift

O. L. Dors, B. Agarwal, G. F. Hagele +5

We built a grid of photoionization models and compiled already available observational emission line intensities () of confirmed star formation…

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^…

Predicting the locations of possible long-lived low-mass first stars: Importance of satellite dwarf galaxies

Mattis Magg, Tilman Hartwig, Bhaskar Agarwal +4

The search for metal-free stars has so far been unsuccessful, proving that if there are surviving stars from the first generation, they are rare, they have been polluted, or we hav…
