Using SquiRels to Find LiMRs: A Model-Insensitive Approach to Cosmic Microwave Background Studies of Light but Massive Relics
Nicholas DePorzio, David Imig, Jessie Shelton
The paper introduces a phenomenological framework called SquiRels to model light but massive relics (LiMRs) in a model‑agnostic way, using CMB data to set limits on LiMRs that beco…

Gravitational Wave and CMB Probes of Axion Kination
Raymond T. Co, David Dunsky, Nicolas Fernandez +4
Rotations of an axion field in field space provide a natural origin for an era of kination domination, where the energy density is dominated by the kinetic term of the axion field,…
