Kavli Affiliate: Lina Necib | First 5 Authors: Arpit Arora, Robyn E. Sanderson, Sukanya Chakrabarti, Andrew Wetzel, Thomas Donlon II | Summary: Measurements of the accelerations of stars enabled by time-series extreme-precision spectroscopic observations, from pulsar timing, and from eclipsing binary stars in the Solar Neighborhood offer insights into the mass distribution of the Milky […]
Kavli Affiliate: Herman L. Marshall | First 5 Authors: James F. Steiner, Edward Nathan, Kun Hu, Henric Krawczynski, Michal Dovciak | Summary: We present the first X-ray spectropolarimetric results for Cygnus X-1 in its soft state from a campaign of five IXPE observations conducted during 2023 May-June. Companion multiwavelength data during the campaign are likewise […]

Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Kenzie Nimmo, Ziggy Pleunis, Paz Beniamini, Pawan Kumar, Adam E. Lanman | Summary: Fast radio bursts (FRBs) are micro-to-millisecond duration radio transients that originate mostly from extragalactic distances. The emission mechanism responsible for these high luminosity, short duration transients remains debated. The models are broadly grouped […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Eric Zhang, Laura V Sales, Federico Marinacci, Paul Torrey, Mark Vogelsberger | Summary: Simulations of galaxy formation are mostly unable to resolve the energy-conserving phase of individual supernova events, having to resort to subgrid models to distribute the energy and momentum resulting from stellar feedback. However, the […]
Kavli Affiliate: Avi Shporer | First 5 Authors: Molly Nies, Ismael Mireles, François Bouchy, Diana Dragomir, Belinda A. Nicholson | Summary: We report the discovery and validation of HD 21520 b, a transiting planet found with TESS and orbiting a bright G dwarf (V=9.2, $T_{eff} = 5871 pm 62$ K, $R_{star} = 1.04pm 0.02, R_{odot}$). […]
Kavli Affiliate: Max Tegmark | First 5 Authors: Chloe Loughridge, Qinyi Sun, Seth Ahrenbach, Federico Cassano, Chuyue Sun | Summary: We introduce DafnyBench, the largest benchmark of its kind for training and evaluating machine learning systems for formal software verification. We test the ability of LLMs such as GPT-4 and Claude 3 to auto-generate enough […]
Kavli Affiliate: George R. Ricker | First 5 Authors: Pa Chia Thao, Andrew W. Mann, Madyson G. Barber, Adam L. Kraus, Benjamin M. Tofflemire | Summary: Young (<500 Myr) planets are critical to studying how planets form and evolve. Among these young planetary systems, multi-planet configurations are particularly useful as they provide a means to […]

Tofflemire | Summary: Young (<500 Myr) planets are critical to studying how planets form and evolve. Among these young planetary systems, multi-planet configurations are particularly useful as they provide a means to control […]
