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…
An analytic resolution to the competition between Lyman-Werner radiation and metal winds in direct collapse black hole hosts
Bhaskar Agarwal, John Regan, Ralf S. Klessen +2
A near pristine atomic cooling halo close to a star forming galaxy offers a natural pathway for forming massive direct collapse black hole (DCBH) seeds which could be the progenito…
On the formation of the first quasars
Rosa Valiante, Bhaskar Agarwal, Melanie Habouzit +1
Observations of the most luminous quasars at redshift z>6 reveal the existence of numerous supermasssive black holes (>10^9 Msun) already in place about twelve billion years ago. I…
Metallicity evolution of direct collapse black hole hosts: CR7 as a case study
Bhaskar Agarwal, Jarrett L. Johnson, Sadegh Khochfar +4
In this study we focus on the Lyman- CR7 consisting of clump A that is host to a potential direct collapse black hole (DCBH), and two metal enriched star forming clum…
Lyman-Werner Escape Fractions from the First Galaxies
Anna T. P. Schauer, Bhaskar Agarwal, Simon C. O. Glover +6
Direct collapse black holes forming in pristine, atomically-cooling haloes at may act as the seeds of supermassive black holes (BH) at high redshifts. In order to…
