Kavli Affiliate: Peter W. Graham | First 5 Authors: Xing Fan, Gerald Gabrielse, Peter W. Graham, Roni Harnik, Thomas G. Myers | Summary: We propose using trapped electrons as high-$Q$ resonators for detecting meV dark photon dark matter. When the rest energy of the dark photon matches the energy splitting of the two lowest cyclotron […]

Kavli Affiliate: Bruce Macintosh | First 5 Authors: Jason J. Wang, Peter Gao, Jeffrey Chilcote, Julien Lozi, Olivier Guyon | Summary: The atmospheres of gas giant planets are thought to be inhomogeneous due to weather and patchy clouds. We present two full nights of coronagraphic observations of the HR 8799 planets using the CHARIS integral […]
Kavli Affiliate: Eric Charles | First 5 Authors: Ke Fang, Matthew Kerr, Roger Blandford, Henrike Fleischhack, Eric Charles | Summary: The existence of a "knee" at energy ~1 PeV in the cosmic-ray spectrum suggests the presence of Galactic PeV proton accelerators called "PeVatrons". Supernova Remnant (SNR) G106.3+2.7 is a prime candidate for one of these. […]

Kavli Affiliate: Eric Charles | First 5 Authors: Regina Caputo, Marco Ajello, Carolyn Kierans, Jeremy Perkins, Judith Racusin | Summary: The All-sky Medium Energy Gamma-ray Observatory eXplorer (AMEGO-X) is designed to identify and characterize gamma rays from extreme explosions and accelerators. The main science themes include: supermassive black holes and their connections to neutrinos and […]

Kavli Affiliate: Robert L. Byer | First 5 Authors: Yen-Chieh Huang, Robert L. Byer, , , | Summary: A dielectric laser accelerator, operating at optical frequencies and GHz pulse rate, is expected to produce attosec electron bunches with a moderate beam current at high energy. For relativistic electrons, the attosec bunch has a spatial length […]
