Kavli Affiliate: Clarence Chang | First 5 Authors: Jesse Liu, Kristin Dona, Gabe Hoshino, Stefan Knirck, Noah Kurinsky | Summary: We introduce the Broadband Reflector Experiment for Axion Detection (BREAD) conceptual design and science program. This haloscope plans to search for bosonic dark matter across the [10$^{-3}$, 1] eV ([0.24, 240] THz) mass range. BREAD […]

Kavli Affiliate: Steven Allen, Lindsey E. Bleem, Bradford Benson, Adam B. Mantz | First 5 Authors: Adam B. Mantz, Steven W. Allen, Rebecca E. A. Canning, Lucie Baumont, Bradford Benson | Summary: We present updated cosmological constraints from measurements of the gas mass fractions ($f_{gas}$) of massive, dynamically relaxed galaxy clusters. Our new data set […]
Kavli Affiliate: Michael D. Gladders | First 5 Authors: Gourav Khullar, Matthew B. Bayliss, Michael D. Gladders, Keunho J. Kim, Michael S Calzadilla | Summary: Using stellar population synthesis models to infer star formation histories (SFHs), we analyse photometry and spectroscopy of a large sample of quiescent galaxies which are members of Sunyaev-Zel’dovich (SZ)-selected galaxy […]
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: 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 […]
Kavli Affiliate: Thomas M. Crawford | First 5 Authors: Michael Janssen, Heino Falcke, Matthias Kadler, Eduardo Ros, Maciek Wielgus | Summary: Very-long-baseline interferometry (VLBI) observations of active galactic nuclei at millimeter wavelengths have the power to reveal the launching and initial collimation region of extragalactic radio jets, down to $10-100$ gravitational radii ($r_g=GM/c^2$) scales in […]
Kavli Affiliate: Daniel E. Holz | First 5 Authors: Igor Andreoni, Raffaella Margutti, Om Sharan Salafia, B. Parazin, V. Ashley Villar | Summary: The discovery of the electromagnetic counterpart to the binary neutron star merger GW170817 has opened the era of gravitational-wave multi-messenger astronomy. Rapid identification of the optical/infrared kilonova enabled a precise localization of […]
Kavli Affiliate: John E. Carlstrom | First 5 Authors: Kaushik Satapathy, Dimitrios Psaltis, Feryal Ozel, Lia Medeiros, Sean T. Dougall | Summary: The black-hole images obtained with the Event Horizon Telescope (EHT) are expected to be variable at the dynamical timescale near their horizons. For the black hole at the center of the M87 galaxy, […]
Kavli Affiliate: Alexander P. Ji | First 5 Authors: Sal Wanying Fu, Daniel R. Weisz, Else Starkenburg, Nicolas Martin, Alexander P. Ji | Summary: We use deep narrowband Ca H&K ($F395N$) imaging taken with the Hubble Space Telescope (HST) to construct the metallicity distribution function (MDF) of Local Group (LG) ultra-faint dwarf (UFD) galaxy Eridanus […]
