Kavli Affiliate: David P. Huenemoerder | First 5 Authors: Sean J. Gunderson, David P. Huenemoerder, José M. Torrejón, Dustin K. Swarm, Joy S. Nichols | Summary: We investigated the temporal and spectral features of $gamma$ Cassiopeiae’s X-ray emission within the context of the white dwarf accretion hypothesis. We find that the variabilities present in the […]
Kavli Affiliate: Michael McDonald | First 5 Authors: Ben W. Reichardt, Adam Paetznick, David Aasen, Ivan Basov, Juan M. Bello-Rivas | Summary: Transitioning from quantum computation on physical qubits to quantum computation on encoded, logical qubits can improve the error rate of operations, and will be essential for realizing valuable quantum computational advantages. Using a […]
Kavli Affiliate: Jacqueline N. Hewitt | First 5 Authors: Kai-Feng Chen, Michael J. Wilensky, Adrian Liu, Joshua S. Dillon, Jacqueline N. Hewitt | Summary: The precise characterization and mitigation of systematic effects is one of the biggest roadblocks impeding the detection of the fluctuations of cosmological 21cm signals. Missing data in radio cosmological experiments, often […]

Kavli Affiliate: Saul Rappaport | First 5 Authors: Jim Fuller, Saul Rappaport, Rahul Jayaraman, Don Kurtz, Gerald Handler | Summary: Stars in close binaries are tidally distorted, and this has a strong effect on their pulsation modes. We compute the mode frequencies and geometries of tidally distorted stars using perturbation theory, accounting for the effects […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Nathan Jamieson, Aaron Smith, Meredith Neyer, Rahul Kannan, Enrico Garaldi | Summary: The growth of ionized hydrogen bubbles in the intergalactic medium around early luminous objects is a fundamental process during the Epoch of Reionization (EoR). In this study, we analyze bubble sizes and their evolution using […]
Kavli Affiliate: Nergis Mavalvala | First 5 Authors: Roman Schnabel, Nergis Mavalvala, David E. McClelland, Ping Koy Lam, | Summary: Einstein’s General Theory of Relativity predicts that accelerating mass distributions produce gravitational radiation, analogous to electromagnetic radiation from accelerating charges. These gravitational waves have not been directly detected to date, but are expected to open […]
Kavli Affiliate: Dheeraj Pasham | First 5 Authors: Dheeraj Pasham, Eric Coughlin, Chris Nixon, Michal Zajacek, Petra Sukova | Summary: SwJ023017.0+283603 (SwJ0230) exhibited soft X-ray (0.3-1.0 keV) eruptions recurring roughly every 22 days. We present results from an extended monitoring campaign of SwJ0230 using Swift, NICER, and deep XMM-Newton observations. Our main findings are: 1) […]
Kavli Affiliate: Dheeraj R. Pasham | First 5 Authors: Petra Suková, Francesco Tombesi, Dheeraj R. Pasham, Michal Zajaček, Thomas Wevers | Summary: In the last few years, a mysterious new class of astrophysical objects has been uncovered. These are spatially coincident with the nuclei of external galaxies and show X-ray variations that repeat on timescales […]
Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Alice P. Curtin, Ketan R. Sand, Ziggy Pleunis, Naman Jain, Victoria Kaspi | Summary: The Canadian Hydrogen Intensity Mapping Experiment Fast Radio Burst (CHIME/FRB) project has discovered the most repeating fast radio burst (FRB) sources of any telescope. However, most of the physical conclusions derived from […]
