A Dark Matter Trigger for Early Dark Energy Coincidence
Meng-Xiang Lin, Evan McDonough, J. Colin Hill +1
Early dark energy (EDE), whose cosmological role is localized in time around the epoch of matter-radiation equality in order to resolve the Hubble tension, introduces a new coincid…
Towards A Direct Detection of the Spin of Dark Matter
Leah Jenks, Konstantinos Koutrolikos, Evan McDonough +2
We investigate the contribution of higher spin particles in the signal of direct detection experiments searching for dark matter. We consider a bosonic or fermionic higher spin dar…
Completely Dark Matter from Rapid-Turn Multifield Inflation
Edward W. Kolb, Andrew J. Long, Evan McDonough +1
We study cosmological gravitational particle production as applied to "rapid-turn" models of inflation involving two scalar fields. We are interested in the production of massive s…
Towards Early Dark Energy in String Theory
Evan McDonough, Marco Scalisi
Early Dark Energy (EDE) is a prominent model to resolve the Hubble tension, which employs a dynamical axion with a periodic potential. In this work, we take first steps towards the…
Ultra-Light Pion and Baryon WIMPzilla Dark Matter
Azadeh Maleknejad, Evan McDonough
We consider a dark confining gauge theory with millicharged Ultra-Light Pions (ULP) and heavy baryons as dark matter candidates. The model simultaneously realizes the ultra-light (…
Primordial Black Holes from Multifield Inflation with Nonminimal Couplings
Sarah R. Geller, Wenzer Qin, Evan McDonough +1
Primordial black holes (PBHs) provide an exciting prospect for accounting for dark matter. In this paper, we consider inflationary models that incorporate realistic features from h…
