Updated and Projected Cosmic Microwave Background Bounds on WIMP Annihilation
Charlotte Myers, Dominic Agius, Daniele Gaggero +1
We derive updated Cosmic Microwave Background (CMB) constraints on annihilating dark matter, and present forecasts for upcoming CMB surveys. We show that the addition of recent tem…
Boosting the cosmic 21-cm signal with exotic Lyman- from dark matter
Dominic Agius, Tracy Robyn Slatyer
The 21-cm signal from the epoch of cosmic dawn () offers a powerful probe of new physics. One standard mechanism for constraining decaying dark matter from 21-cm obse…
Astrophysical uncertainties challenge 21-cm forecasts: A primordial black hole case study
Dominic Agius, Rouven Essig, Daniele Gaggero +3
The 21-cm signal is a powerful probe of the early Universe's thermal history and could provide a unique avenue for constraining exotic physics. Previous studies have forecasted str…
Feedback in the dark: a critical examination of CMB bounds on primordial black holes
Dominic Agius, Rouven Essig, Daniele Gaggero +3
If present in the early universe, primordial black holes (PBHs) will accrete matter and emit high-energy photons, altering the statistical properties of the {Cosmic Microwave Backg…
