Connecting cosmologically decaying dark matter to neutrino physics
Lea Fuß, Mathias Garny, Alejandro Ibarra
Dark matter decays into invisible particles can leave an imprint in large-scale structure surveys due to a characteristic redshift-dependent suppression of the power spectrum. We p…

Minimal decaying dark matter: from cosmological tensions to neutrino signatures
Lea Fuß, Mathias Garny, Alejandro Ibarra
The invisible decay of cold dark matter into a slightly lighter dark sector particle on cosmological time-scales has been proposed as a solution to the tension. In this work…
