Kavli Affiliate: Michael Crisler | First 5 Authors: Liron Barak, Itay M. Bloch, Mariano Cababie, Gustavo Cancelo, Luke Chaplinsky | Summary: We present the first direct-detection search for eV-to-GeV dark matter using a new ~2-gram high-resistivity Skipper-CCD from a dedicated fabrication batch that was optimized for dark-matter searches. Using 24 days of data acquired in […]
Kavli Affiliate: Renxin Xu | First 5 Authors: Shuang Du, Weihua Wang, Xuhao Wu, Renxin Xu, | Summary: We propose a geometrical explanation for periodically and nonperiodically repeating fast radio bursts (FRBs) under neutron star (NS)-companion systems. We suggest a constant critical binary separation, $r_{rm c}$, within which the interaction between the NS and companion […]
Kavli Affiliate: Giorgio Gratta | First 5 Authors: Akio Kawasaki, Alexander Fieguth, Nadav Priel, Charles P. Blakemore, Denzal Martin | Summary: A high sensitivity force sensor based on dielectric microspheres in vacuum, optically trapped by a single, upward-propagating laser beam, is described. Off-axis parabolic mirrors are used both to focus the 1064~nm trapping beam and […]
