Searching for Dark Clumps with Gravitational-Wave Detectors
Sebastian Baum, Michael A. Fedderke, Peter W. Graham
Dark compact objects ("clumps") transiting the Solar System exert accelerations on the test masses (TM) in a gravitational-wave (GW) detector. We reexamine the detectability of the…
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…
Axion Dark Matter Detection with CMB Polarization
Michael A. Fedderke, Peter W. Graham, Surjeet Rajendran
We point out two ways to search for low-mass axion dark matter using cosmic microwave background (CMB) polarization measurements. These appear, in particular, to be some of the mos…
Irruption of massive particle species during inflation
Michael A. Fedderke, Edward W. Kolb, Mark Wyman
All species of (non-conformally-coupled) particles are produced during inflation so long as their mass is not too much larger than , the expansion rate during inflation. It…
