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…
Population III X-Ray Binaries
Taeho Ryu, Takamitsu L. Tanaka, Rosalba Perna
Understanding of the role of X-rays for driving the thermal evolution of the intergalactic medium (IGM) at high redshifts is one of important questions in astrophysics. High-mass X…
On the likelihood of detecting gravitational waves from Population III compact object binaries
K. Belczynski, T. Ryu, R. Perna +3
We study the contribution of binary black hole (BH-BH) mergers from the first, metal-free stars in the Universe (Pop III) to gravitational wave detection rates. Our study combines…
Flares in Gamma Ray Bursts: Disc Fragmentation and Evolution
Simone Dall'Osso, Rosalba Perna, Takamitsu L. Tanaka +1
Flaring activity following gamma-ray bursts (GRBs), observed in both long and short GRBs, signals a long-term activity of the central engine. However, its production mechanism has…
Intermediate-mass black holes from Population III remnants in the first galactic nuclei
Taeho Ryu, Takamitsu L. Tanaka, Rosalba Perna +1
We report the formation of intermediate-mass black holes (IMBHs) in suites of numerical -body simulations of Population III remnant black holes (BHs) embedded in gas-rich protog…
Formation, disruption and energy output of Population III X-ray binaries
Taeho Ryu, Takamitsu L. Tanaka, Rosalba Perna
The first astrophysical objects shaped the cosmic environment by reionizing and heating the intergalactic medium (IGM). In particular, X-rays are very efficient at heating the IGM…
