Kavli Affiliate: Michael Crisler | First 5 Authors: SENSEI Collaboration, Prakruth Adari, Itay M. Bloch, Ana M. Botti, Mariano Cababie | Summary: We present the first results from a dark matter search using six Skipper-CCDs in the SENSEI detector operating at SNOLAB. With an exposure of 534.9 gram-days from well-performing sensors, we select events containing […]
Kavli Affiliate: Michael Crisler | First 5 Authors: SENSEI Collaboration, Prakruth Adari, Itay M. Bloch, Ana M. Botti, Mariano Cababie | Summary: We present the first results from a dark matter search using six Skipper-CCDs in the SENSEI detector operating at SNOLAB. We employ a bias-mitigation technique of hiding approximately 46% of our total data […]
Kavli Affiliate: Clarence Chang | First 5 Authors: Juliang Li, Pete Barry, Tom Cecil, Marharyta Lisovenko, Volodymyr Yefremenko | Summary: We present a design and implementation of frequency-tunable superconducting resonator. The resonance frequency tunability is achieved by flux-coupling a superconducting LC-loop to a current-biased feedline; the resulting screening current leads to a change of the […]
Kavli Affiliate: Daniel Holz | First 5 Authors: Thomas Callister, Leah Jenks, Daniel Holz, Nicolás Yunes, | Summary: Parity violation in the gravitational sector is a prediction of many theories beyond general relativity. In the propagation of gravitational waves, parity violation manifests by inducing amplitude and/or velocity birefringence between right- and left-circularly polarized modes. We […]
Kavli Affiliate: Michael D. Gladders | First 5 Authors: Jane R. Rigby, Joaquin D. Vieira, Kedar A. Phadke, Taylor A. Hutchison, Brian Welch | Summary: This paper gives an overview of TEMPLATES, a JWST Early Release Science program that targeted four extremely bright, gravitationally lensed galaxies: two extremely dusty, two with low attenuation, as templates […]
Kavli Affiliate: Brian Nord | First 5 Authors: Maggie Voetberg, Brian Nord, , , | Summary: Modern astronomical surveys have multiple competing scientific goals. Optimizing the observation schedule for these goals presents significant computational and theoretical challenges, and state-of-the-art methods rely on expensive human inspection of simulated telescope schedules. Automated methods, such as reinforcement learning, […]
Kavli Affiliate: Edward W. Kolb | First 5 Authors: Edward W. Kolb, Andrew J. Long, , , | Summary: Cosmological gravitational particle production (CGPP) is the creation of particles in an expanding universe due solely to their gravitational interaction. These particles can play an important role in the cosmic history through their connection to various […]

Kavli Affiliate: Michael D. Gladders | First 5 Authors: Osase Omoruyi, Grant R. Tremblay, Francoise Combes, Timothy A. Davis, Michael D. Gladders | Summary: With two central galaxies engaged in a major merger and a remarkable chain of 19 young stellar superclusters wound around them in projection, the galaxy cluster SDSS J1531+3414 ($z=0.335$) offers an […]
Kavli Affiliate: Austin Joyce | First 5 Authors: Nima Arkani-Hamed, Daniel Baumann, Aaron Hillman, Austin Joyce, Hayden Lee | Summary: Perhaps the most basic question we can ask about cosmological correlations is how their strength changes as we smoothly vary kinematic parameters. The answer is encoded in differential equations that govern this evolution in kinematic […]
