Kavli Affiliate: Peter Fritschel | First 5 Authors: Varun Srivastava, Georgia Mansell, Camille Makarem, Minkyun Noh, Richard Abbott | Summary: The detectors of the laser interferometer gravitational-wave observatory (LIGO) are broadly limited by the quantum noise and rely on the injection of squeezed states of light to achieve their full sensitivity. Squeezing improvement is limited […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Zhichao Carton Zeng, Annika H. G. Peter, Xiaolong Du, Andrew Benson, Stacy Kim | Summary: Self-interacting dark matter (SIDM) cosmologies admit an enormous diversity of dark matter (DM) halo density profiles, from low-density cores to high-density core-collapsed cusps. The possibility of the growth of high central density […]
Kavli Affiliate: Christopher Burke | First 5 Authors: Bryson Cale, Michael Reefe, Peter Plavchan, Angelle Tanner, Eric Gaidos | Summary: We present updated radial-velocity (RV) analyses of the AU Mic system. AU Mic is a young (22 Myr) early M dwarf known to host two transiting planets – $P_{b}sim8.46$ days, $R_{b}=4.38_{-0.18}^{+0.18} R_{oplus}$, $P_{c}sim18.86$ days, $R_{c}=3.51_{-0.16}^{+0.16} […]
Kavli Affiliate: Max Tegmark | First 5 Authors: Ziming Liu, Yunyue Chen, Yuanqi Du, Max Tegmark, | Summary: Integrating physical inductive biases into machine learning can improve model generalizability. We generalize the successful paradigm of physics-informed learning (PIL) into a more general framework that also includes what we term physics-augmented learning (PAL). PIL and PAL […]
Kavli Affiliate: Jacqueline N. Hewitt | First 5 Authors: Dara Storer, Joshua S. Dillon, Daniel C. Jacobs, Miguel F. Morales, Bryna J. Hazelton | Summary: We present a framework for identifying and flagging malfunctioning antennas in large radio interferometers. We outline two distinct categories of metrics designed to detect outliers along known failure modes of […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Hui Li, Mark Vogelsberger, Greg L. Bryan, Federico Marinacci, Laura V. Sales | Summary: Galaxy mergers are known to host abundant young massive cluster (YMC) populations, whose formation mechanism is still not well-understood. Here, we present a high-resolution galaxy merger simulation with explicit star formation and stellar […]
Kavli Affiliate: David H. Shoemaker | First 5 Authors: Matthew Evans, Rana X Adhikari, Chaitanya Afle, Stefan W. Ballmer, Sylvia Biscoveanu | Summary: This Horizon Study describes a next-generation ground-based gravitational-wave observatory: Cosmic Explorer. With ten times the sensitivity of Advanced LIGO, Cosmic Explorer will push gravitational-wave astronomy towards the edge of the observable universe […]

Ballmer, Sylvia Biscoveanu | Summary: This Horizon Study describes a next-generation ground-based gravitational-wave observatory: Cosmic Explorer. With ten times the sensitivity of Advanced LIGO, Cosmic Explorer will push gravitational-wave astronomy towards the edge of the observable universe ($z […]
Kavli Affiliate: Max Tegmark | First 5 Authors: Ziming Liu, Max Tegmark, , , | Summary: We present an automated method for finding hidden symmetries, defined as symmetries that become manifest only in a new coordinate system that must be discovered. Its core idea is to quantify asymmetry as violation of certain partial differential equations, […]
Kavli Affiliate: Michael Fausnaugh | First 5 Authors: Benjamin J. Hord, Knicole D. Colón, Veselin Kostov, Brianna Galgano, George R. Ricker | Summary: We present the results of a uniform search for additional planets around all stars with confirmed hot Jupiters observed by the Transiting Exoplanet Survey Satellite (TESS) in its Cycle 1 survey of […]
