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…
Fine-Tuning, Complexity, and Life in the Multiverse
Mario Livio, Martin J. Rees
The physical processes that determine the properties of our everyday world, and of the wider cosmos, are determined by some key numbers: the 'constants' of micro-physics and the pa…
Axial-Vector Emitting Weak Nonleptonic Deacys of Baryon
Rohit Dhir, C. S. Kim
The axial-vector emitting weak hadronic decays of baryon are investigated. After employing the factorization and the pole model framework to predict their branching ratios,…
Cosmic Feedback from Supermassive Black Holes
A. Fabian, E. Churazov, M. Donahue +16
An extraordinary recent development in astrophysics was the discovery of the fossil relationship between central black hole mass and the stellar mass of galactic bulges. The physic…
Implications of very rapid TeV variability in blazars
Mitchell C. Begelman, Andrew C. Fabian, Martin J. Rees
We discuss the implications of rapid (few-minute) variability in the TeV flux of blazars, which has been observed recently with the HESS and MAGIC telescopes. The variability times…
A new method of determining the initial size and Lorentz factor of gamma-ray burst fireballs using a thermal emission component
Asaf Pe'er, Felix Ryde, Ralph A. M. J. Wijers +2
In recent years increasing evidence has emerged for a thermal component in the gamma- and X-ray spectrum of the prompt emission phase in gamma-ray bursts. The temperature and flux…
