Description
Cosmic filaments form the structure of the cosmic web, with dark matter making up the majority of their mass. If GeV-scale dark matter particles in filaments decay into electron-positron pairs, they could generate radio waves through synchrotron radiation. A realistic description of the expected dark matter decay signals from cosmic filaments requires a detailed characterization of the dark matter distribution within them. I will present the dark matter density profiles in filaments extracted from state-of-the-art cosmological simulations and discuss their implications for indirect detection signals from dark matter decay. In particular, I will focus on the decay of dark matter into electron-positron pairs and discuss the resulting constraints on the dark matter decay lifetime.
