Stellar Signatures of Inhomogeneous Big Bang Nucleosynthesis
Alexandre Arbey, Jérémy Auffinger, Joseph Silk
We evaluate abundance anomalies generated in patches of the universe where the baryon-to-photon ratio was locally enhanced by possibly many orders of magnitude in the range $η= 10^…
Constraining primordial black hole masses with the isotropic gamma ray background
Alexandre Arbey, Jérémy Auffinger, Joseph Silk
Primordial black holes can represent all or most of the dark matter in the window g. Here we present an extension of the constraints on PBHs of masses $10^{13}-1…
Evolution of primordial black hole spin due to Hawking radiation
Alexandre Arbey, Jérémy Auffinger, Joseph Silk
Near extremal Kerr black holes are subject to the Thorne limit in the case of thin disc accretion, or some generalized version of this in other disc geometr…
Linear growth of streaming instability in pressure bumps
Jérémy Auffinger, Guillaume Laibe
Streaming instability is a powerful mechanism which concentrates dust grains in pro- toplanetary discs, eventually up to the stage where they collapse gravitationally and form plan…
