Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Ayush Pandhi, Ziggy Pleunis, Ryan Mckinven, B. M. Gaensler, Jianing Su | Summary: We present a 400-800 MHz polarimetric analysis of 128 non-repeating fast radio bursts (FRBs) from the first CHIME/FRB baseband catalog, increasing the total number of FRB sources with polarization properties by a factor […]

Kavli Affiliate: Michael Fausnaugh | First 5 Authors: Daniel A. Perley, Anna Y. Q. Ho, Michael Fausnaugh, Gavin P. Lamb, Mansi M. Kasliwal | Summary: Classical gamma-ray bursts (GRBs) have two distinct emission episodes: prompt emission from ultra-relativistic ejecta and afterglow from shocked circumstellar material. While both components are extremely luminous in known GRBs, a […]

Kavli Affiliate: Sara Seager | First 5 Authors: Angelica Psaridi, Hugh Osborn, François Bouchy, Monika Lendl, Léna Parc | Summary: We present the discovery and characterization of two warm mini-Neptunes transiting the K3V star TOI-815 in a K-M binary system. Analysis of the spectra and rotation period reveal it to be a young star with […]
Kavli Affiliate: Eric Miller | First 5 Authors: Michael Wojnowicz, Preetish Rath, Eric Miller, Jeffrey Miller, Clifford Hancock | Summary: We seek to model a collection of time series arising from multiple entities interacting over the same time period. Recent work focused on modeling individual time series is inadequate for our intended applications, where collective […]
Kavli Affiliate: Erin Kara | First 5 Authors: Tingting Liu, Rick Edelson, Juan V. Hernández Santisteban, Erin Kara, John Montano | Summary: We present an intensive multiwavelength monitoring campaign of the quasar PG 1302$-$102 with Swift and the Las Cumbres Observatory network telescopes. At $zsim0.3$, it tests the limits of the reverberation mapping (RM) technique […]
Kavli Affiliate: Max Tegmark | First 5 Authors: Stephen Casper, Carson Ezell, Charlotte Siegmann, Noam Kolt, Taylor Lynn Curtis | Summary: External audits of AI systems are increasingly recognized as a key mechanism for AI governance. The effectiveness of an audit, however, depends on the degree of system access granted to auditors. Recent audits of […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Aidan Leonard, Stephanie O’Neil, Xuejian Shen, Mark Vogelsberger, Olivia Rosenstein | Summary: Self-interacting dark matter (SIDM) is increasingly studied as a potential solution to small-scale discrepancies between simulations of cold dark matter (CDM) and observations. We examine a physically motivated two-state SIDM model with both elastic and […]
