Thermal Damping of Mass-Modulating Scalars
Abhishek Banerjee, Ngan H. Nguyen, Erwin H. Tanin
The cosmological evolution of a scalar field is shaped by Hubble damping. Any non-gravitational couplings of the scalar with the primordial thermal bath generically contribute addi…
Cosmological Limits on Strong Dark Forces
Peter W. Graham, Harikrishnan Ramani, Olivier Simon +1
We showcase cosmology's ability to constrain long-range forces between dark matter particles. Specifically, we consider a fermionic dark matter interacting via a Yukawa-coupled lig…
Thermal Damping of Neutrino-Coupled Scalar Dark Matter
Abhishek Banerjee, Ngan H. Nguyen, Erwin H. Tanin
We point out that ultralight scalar dark matter that modulates neutrino masses can be significantly thermal damped by cosmic neutrinos in the early universe. This dissipative effec…
Mineral Detection of Neutrinos and Dark Matter 2025 Proceedings
Shigenobu Hirose, Patrick Stengel, Natsue Abe +70
The third ``Mineral Detection of Neutrinos and Dark Matter'' (MDDM'25) meeting was held May 20-23, 2025 in Yokohama, Japan, hosted by the Yokohama Institute for Earth Sciences,…
Gravothermal Pile-Up of Collisional Dark Matter Around Compact Objects
Reza Ebadi, Erwin H. Tanin
The dark matter may consist of multiple species that interact differently. We show that a species that is cosmologically subdominant but highly collisional can pile up and become d…
