Simulation-based inference on warm dark matter from HERA forecasts

Quentin Decant, Androniki Dimitriou, Laura Lopez Honorez +1

The redshifted 21cm signal from Cosmic Dawn promises to open a new window into the early history of our universe and enable the probing of an unprecedented comoving survey volume.…

Lyman- constraints on freeze-in and superWIMPs

Quentin Decant, Jan Heisig, Deanna C. Hooper +1

Dark matter (DM) from freeze-in or superWIMP production is well known to imprint non-cold DM signatures on cosmological observables. We derive constraints from Lyman- forest ob…

Non-Cold Dark Matter from Primordial Black Hole Evaporation

Iason Baldes, Quentin Decant, Deanna C. Hooper +1

Dark matter coupled solely gravitationally can be produced through the decay of primordial black holes in the early universe. If the dark matter is lighter than the initial black h…

Dark matter from WIMP to FIMP over three regimes: Cosmology versus Colliders

Laura Lopez-Honorez, Quentin Decant, Sam Junius +1

Dark matter models can give rise to specific signatures at particle physics experiments or in cosmology. The details of the cosmological history can also influence the new physics…

Cosmological imprints of non-thermalized dark matter

Quentin Decant, Jan Heisig, Deanna C. Hooper +1

Non-thermalized dark matter is a cosmologically viable alternative to the widely studied weakly interacting massive particle. We study the evolution of the dark matter phase-space…
