Optical Photometric Indicators of Galaxy Cluster Relaxation

Kavli Affiliate: Steven W. Allen | First 5 Authors: Madeline C. Casas, Ky Putnam, Adam B. Mantz, Steven W. Allen, Taweewat Somboonpanyakul | Summary: The most dynamically relaxed clusters of galaxies play a special role in cosmological studies as well as astrophysical studies of the intracluster medium (ICM) and active galactic nucleus feedback. While high […]

Modeling Phonon-mediated Quasiparticle Poisoning in Superconducting Qubit Arrays

Kavli Affiliate: Noah Kurinsky | First 5 Authors: Eric Yelton, Clayton P. Larson, Vito Iaia, Kenneth Dodge, Guglielmo La Magna | Summary: Correlated errors caused by ionizing radiation impacting superconducting qubit chips are problematic for quantum error correction. Such impacts generate quasiparticle (QP) excitations in the qubit electrodes, which temporarily reduce qubit coherence significantly. The […]

How the Galaxy-Halo Connection Depends on Large-Scale Environment

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: John F. Wu, Christian Kragh Jespersen, Risa H. Wechsler, , | Summary: We investigate the connection between galaxies, dark matter halos, and their large-scale environments with Illustris TNG300 hydrodynamic simulation data. We predict stellar masses from subhalo properties to test two types of machine learning (ML) […]
