Kavli Affiliate: Brian Nord | First 5 Authors: Michelle Ntampaka, Matthew Ho, Brian Nord, , | Summary: Astronomy is entering an era of data-driven discovery, due in part to modern machine learning (ML) techniques enabling powerful new ways to interpret observations. This shift in our scientific approach requires us to consider whether we can trust […]
Kavli Affiliate: Michael S. Turner | First 5 Authors: Michael S. Turner, KICP/UChicago, The Kavli Foundation, , | Summary: Big-bang nucleosynthesis (BBN), a pillar of modern cosmology, begins with the trailblazing 1948 paper of Alpher, Bethe and Gamow cite{abc} which proposed nucleosynthesis during an early ($t sim 1 – 1000,$sec), radiation-dominated phase of the Universe […]
Kavli Affiliate: Michael S. Turner | First 5 Authors: Michael S. Turner, KICP/UChicago, The Kavli Foundation, , | Summary: Big-bang nucleosynthesis (BBN), today a pillar of modern cosmology, began with the trailblazing 1948 paper of Alpher, Bethe and Gamow. In it, they proposed non-equilibrium nuclear processes in the early Universe ($t sim 1000,$sec) and an […]
Kavli Affiliate: Katrin Heitmann | First 5 Authors: Nesar Ramachandra, Jonás Chaves-Montero, Alex Alarcon, Arindam Fadikar, Salman Habib | Summary: Photometric redshift estimation algorithms are often based on representative data from observational campaigns. Data-driven methods of this type are subject to a number of potential deficiencies, such as sample bias and incompleteness. Motivated by these […]
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 […]
