Computational Fluid Dynamics with the Coupled Discrete Unified Gas Kinetic Scheme (CDUGKS)

Kavli Affiliate: Tom Abel | First 5 Authors: Alvaro Zamora, Tom Abel, , , | Summary: In this paper, we introduce our open source implementation of the Coupled Discrete Unified Gas Kinetic Scheme (CDUGKS) of https://journals.aps.org/pre/abstract/10.1103/PhysRevE.98.053310, a phase space scheme capable of handling a wide range of flow regimes. We demonstrate its performance on several […]

One-Electron Quantum Cyclotron as a Milli-eV Dark-Photon Detector

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 […]

Atmospheric Monitoring and Precise Spectroscopy of the HR 8799 Planets with SCExAO/CHARIS

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 […]

Evidence for PeV Proton Acceleration from Fermi-LAT Observations of SNR G106.3+2.7

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. […]
