Improved Big Bang Nucleosynthesis constraints on decaying massive relics
Sara Bianco, Jonas Frerick, Marco Hufnagel +1
We present updated and improved Big Bang Nucleosynthesis (BBN) constraints on heavy, long-lived beyond the Standard Model (BSM) relics decaying into pairs of Standard Model par…
The Cosmological Simulation Code OpenGadget3 - Implementation of Self-Interacting Dark Matter
Moritz S. Fischer, Marc Wiertel, Cenanda Arido +7
Dark matter (DM) could be subject to non-gravitational self-interactions which is relevant to resolve potential problems of cold DM on small scales. Their impact on astrophysical o…
Tuning the violins: dark sector phase transition models for the PTA signal
Torsten Bringmann, Thomas Konstandin, Jonas Matuszak +2
First-order phase transitions in a dark sector have been invoked as an intriguing possibility to explain the observed stochastic gravitational wave background at nanohertz frequenc…
Accretion of self-interacting dark matter onto supermassive black holes
V. M. Sabarish, Marcus Brüggen, Kai Schmidt-Hoberg +1
Dark matter (DM) spikes around supermassive black holes (SMBHs) may lead to interesting physical effects such as enhanced DM annihilation signals or dynamical friction within binar…
Photo- and Hadrodisintegration constraints on massive relics decaying into neutrinos
Sara Bianco, Paul Frederik Depta, Jonas Frerick +3
We perform a detailed study of the cosmological constraints on the decay of a relic particle into neutrinos, , in particular those arising from the observe…
Early Matter Domination at Colliders: Long Live the Glueball!
Fady Bishara, Filippo Sala, Kai Schmidt-Hoberg
We prove that collider searches for long-lived particles (LLPs) can test the dynamics responsible for matter domination in the early universe. In this letter we concentrate on the…
