Kavli Affiliate: Max Tegmark | First 5 Authors: Ziming Liu, Ouail Kitouni, Niklas Nolte, Eric J. Michaud, Max Tegmark | Summary: We aim to understand grokking, a phenomenon where models generalize long after overfitting their training set. We present both a microscopic analysis anchored by an effective theory and a macroscopic analysis of phase diagrams […]

Kavli Affiliate: Erin Kara | First 5 Authors: Kishalay De, Ilya Mereminskiy, Roberto Soria, Charlie Conroy, Erin Kara | Summary: We present the discovery and multi-wavelength characterization of SRGA J181414.6-225604, a Galactic hard X-ray transient discovered during the ongoing SRG/ART-XC sky survey. Using data from the Palomar Gattini-IR survey, we identify a spatially and temporally […]

Kavli Affiliate: Herman L. Marshall | First 5 Authors: Roberto Taverna, Roberto Turolla, Fabio Muleri, Jeremy Heyl, Silvia Zane | Summary: We report on the first detection of linearly polarized x-ray emission from an ultra-magnetized neutron star with the Imaging X-ray Polarimetry Explorer (IXPE). The IXPE 35 observations of the anomalous x-ray pulsar 4U 0142+61 […]

Kavli Affiliate: Sara Seager | First 5 Authors: Ana Glidden, Sara Seager, Jingcheng Huang, Janusz J. Petkowski, Sukrit Ranjan | Summary: The search for signs of life on other worlds has largely focused on terrestrial planets. Recent work, however, argues that life could exist in the atmospheres of temperate sub-Neptunes. Here, we evaluate the usefulness […]
Kavli Affiliate: Paul L. Schechter | First 5 Authors: Chirag Falor, Paul L. Schechter, , , | Summary: The quadruple image configurations of gravitational lenses with vanishing ellipticity are examined. Even though such lenses asymptotically approach circularity, the configurations are stable if the position of the source relative to the vanishing diamond caustic is held […]
