Kavli Affiliate: Subo Dong | First 5 Authors: Cheongho Han, Ian A. Bond, Jennifer C. Yee, Weicheng Zang, Michael D. Albrow | Summary: The light curve of the microlensing event KMT-2021-BLG-0912 exhibits a very short anomaly relative to a single-lens single-source form. We investigate the light curve for the purpose of identifying the origin of […]
Kavli Affiliate: Erik Shirokoff, Clarence Chang | First 5 Authors: Karia Dibert, Pete Barry, Zhaodi Pan, Adam Anderson, Bradford Benson | Summary: We present details of the design, simulation, and initial test results of prototype detectors for the fourth-generation receiver of the South Pole Telescope (SPT). Optimized for the detection of key secondary anisotropies of […]
Kavli Affiliate: Hitoshi Murayama | First 5 Authors: Brian Henning, Xiaochuan Lu, Tom Melia, Hitoshi Murayama, | Summary: We discuss anomalies associated with outer automorphisms in gauge theories based on classical groups, namely charge conjugations for $SU(N)$ and parities for $SO(2r)$. We emphasize the inequivalence between two versions of charge conjugation for $SU(N)$ symmetries, and […]
Kavli Affiliate: Tom Melia | First 5 Authors: Weiguang Cao, Tom Melia, Sridip Pal, , | Summary: We give a proof that in any weakly coupled quantum field theory with a finite group global symmetry $mathrm{G}$, on a compact spatial manifold, at sufficiently high energy, the density of states $rho_alpha(E)$ for each irreducible representation $alpha$ […]
Kavli Affiliate: Tom Melia | First 5 Authors: Weiguang Cao, Tom Melia, Sridip Pal, , | Summary: We give a rigorous proof that in any free quantum field theory with a finite group global symmetry $mathrm{G}$, on a compact spatial manifold, at sufficiently high energy, the density of states $rho_alpha(E)$ for each irreducible representation $alpha$ […]
Kavli Affiliate: Subo Dong | First 5 Authors: Cheongho Han, Andrzej Udalski, Chung-Uk Lee, Doeon Kim, Wei Zhu | Summary: With the aim of interpreting anomalous lensing events with no suggested models, we conducted a project of reinvestigating microlensing data in and before the 2019 season. In this work, we report a multi-planet system OGLE-2019-BLG-0468L […]
Kavli Affiliate: Michael McDonald | First 5 Authors: Francesco Ubertosi, Myriam Gitti, Fabrizio Brighenti, Gianfranco Brunetti, Michael McDonald | Summary: We present the first results of a deep $Chandra$ observation of the galaxy cluster RBS 797, whose previous X-ray studies revealed two pronounced X-ray cavities in the east-west (E-W) direction. Follow-up VLA radio observations of […]
Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Alexander Venner, Logan A. Pearce, Andrew Vanderburg, , | Summary: The long-period giant planet HR 5183 b has one of the most extreme orbits among exoplanets known to date. In this work we use Hipparcos-Gaia astrometry to measure the orbital inclination of this planet for the first […]
Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration, R. Abbott, T. D. Abbott | Summary: We report on the population properties of 76 compact binary mergers detected with gravitational waves below a false alarm rate of 1 per year through GWTC-3. The catalog contains three […]
Kavli Affiliate: Daniel E. Holz | First 5 Authors: Amanda M. Farah, Maya Fishbach, Reed Essick, Daniel E. Holz, Shanika Galaudage | Summary: We search for features in the mass distribution of detected compact binary coalescences which signify the transition between neutron stars and black holes. We analyze all gravitational wave detections by LIGO-Virgo made […]
