Mass-varying Dark Matter from a Phase Transition
Sayan Mandal, Neelima Sehgal
We propose a mass-varying dark matter (MVDM) model consisting of a scalar field and a fermionic field interacting via a simple Yukawa coupling, and containing an exponential self-i…
Report of the Topical Group on Dark Energy and Cosmic Acceleration: Complementarity of Probes and New Facilities for Snowmass 2021
Brenna Flaugher, Vivian Miranda, David J. Schlegel +27
The mechanism(s) driving the early- and late-time accelerated expansion of the Universe represent one of the most compelling mysteries in fundamental physics today. The path to und…
Snowmass2021 CMB-HD White Paper
HD Collaboration, Simone Aiola, Yashar Akrami +61
CMB-HD is a proposed millimeter-wave survey over half the sky that would be ultra-deep (0.5 uK-arcmin) and have unprecedented resolution (15 arcseconds at 150 GHz). Such a survey w…
Finding Evidence for Inflation and the Origin of Galactic Magnetic Fields with CMB Surveys
Sayan Mandal, Neelima Sehgal, Toshiya Namikawa
The origin of the G magnetic fields observed in galaxies is unknown. One promising scenario is that magnetic fields generated during inflation, larger than 0.1 nG on Mpc scales,…
