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 pa…
Non-Cold Dark Matter from Memory-Burdened Primordial Black Holes
Valentin Thoss, Laura Lopez-Honorez, Florian Kühnel +1
Non-cold dark matter particles can arise from the evaporation of primordial black holes (PBHs). In this paper, we further investigate how the memory-burden effect, which delays the…
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 obs…
Big Bang Nucleosynthesis constraints on resonant DM annihilations
Pieter Braat, Marco Hufnagel
We perform a systematic study of BBN constraints from photodisintegration for scenarios in which dark-matter annihilations are resonantly-enhanced. To this end, we implement and ma…
