Kavli Affiliate: Takeo Higuchi | First 5 Authors: Latika Aggarwal, Swagato Banerjee, Sunil Bansal, Florian Bernlochner, Michel Bertemes | Summary: Belle II is an experiment operating at the intensity frontier. Over the next decades, it will record the decay of billions of bottom mesons, charm hadrons, and tau leptons produced in 10 GeV electron-positron collisions […]

Kavli Affiliate: Roger Blandford | First 5 Authors: Roger Blandford, Noemie Globus, , , | Summary: A brief summary is given of an alternative interpretation of the Event Horizon Telescope observations of the massive black hole in the nucleus of the nearby galaxy M87. It is proposed that the flow is primarily powered by the […]
Kavli Affiliate: Daniel E. Holz | First 5 Authors: Reed Essick, Will M. Farr, Maya Fishbach, Daniel E. Holz, Erik Katsavounidis | Summary: We constrain the distribution of merging compact binaries across the celestial sphere using the GWTC-3 catalog from the LIGO-Virgo-KAGRA Collaborations’ (LVK) third observing run. With 63 confident detections from O3, we constrain […]
Kavli Affiliate: Jia Liu | First 5 Authors: Haipeng An, Shuailiang Ge, Wen-Qing Guo, Xiaoyuan Huang, Jia Liu | Summary: Dark photon can be the ultralight dark matter candidate, which can interact with the Standard Model particles via the kinetic mixing. We propose to look for ultralight dark photon dark matter (DPDM) with local absorption […]
Kavli Affiliate: Michael D. Gladders | First 5 Authors: Keren Sharon, Catherine Cerny, Jane R. Rigby, Michael K. Florian, Matthew B. Bayliss | Summary: SDSS J1226+2152 is the first extragalactic science target to be observed by JWST. The strongly lensed z=2.9233 Lyman break galaxy, SGAS J122651.3+215220, lensed by a cluster at z=0.4358, was targeted as […]

Bayliss | Summary: The strongly lensed z=2.9233 Lyman break galaxy, SGAS J122651.3+215220, lensed by a cluster at z=0.4358, was first targeted by JWST as part of the JWST-ERS program TEMPLATES: Targeting Extremely Magnified Panchromatic […]
Kavli Affiliate: Ulrich Sperhake | First 5 Authors: Robin Croft, Thomas Helfer, Bo-Xuan Ge, Miren Radia, Tamara Evstafyeva | Summary: In this work we study the long-lived post-merger gravitational wave signature of a boson-star binary coalescence. We use full numerical relativity to simulate the post-merger and track the gravitational afterglow over an extended period of […]
Kavli Affiliate: Roberto Maiolino | First 5 Authors: Jane Rigby, Marshall Perrin, Michael McElwain, Randy Kimble, Scott Friedman | Summary: This document characterizes the actual science performance of the James Webb Space Telescope (JWST), as known on 12 July 2022. Following six months of commissioning to prepare JWST for science operations, the observatory is now […]
Kavli Affiliate: Nicola Omodei | First 5 Authors: Niccolò Bucciantini, Riccardo Ferrazzoli, Matteo Bachetti, John Rankin, Niccolò Di Lalla | Summary: The Crab pulsar and its nebula are among the most studied astrophysical systems, and constitute one of the most promising environments where high energy processes and particle acceleration can be investigated. They are the […]
