Dark forces suppress structure growth
Marco Costa, Cyril Creque-Sarbinowski, Olivier Simon +1
No experimental test precludes the possibility that the dark matter experiences forces beyond general relativity---in fact, a variety of cosmic microwave background observations su…
Abundance and properties of dark radiation from the cosmic microwave background
Murali M. Saravanan, Thejs Brinckmann, Marilena Loverde +1
We study the cosmological signatures of new light relics that are collisionless like standard neutrinos or are strongly interacting. We provide a simple and succinct rephrasing of…
Searching for coupled, hyperlight scalars across cosmic history
Masha Baryakhtar, Olivier Simon, Zachary J. Weiner
Cosmological scalar fields coupled to the Standard Model drive temporal variations in the fundamental constants that grow with redshift, positioning the early Universe as a powerfu…
