Kavli Affiliate: Michael A. McDonald | First 5 Authors: Josh Borrow, Mark Vogelsberger, Stephanie O’Neil, Michael A. McDonald, Aaron Smith | Summary: Backsplash galaxies are galaxies that once resided inside a cluster, and have migrated back oustide as they move towards the apocentre of their orbit. The kinematic properties of these galaxies are well understood, […]
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: Saul A. Rappaport | First 5 Authors: Martti H. K. Kristiansen, Saul A. Rappaport, Andrew M. Vanderburg, Thomas L. Jacobs, Hans Martin Schwengeler | Summary: This article presents the history of the Visual Survey Group (VSG) – a Professional-Amateur (Pro-Am) collaboration within the field of astronomy working on data from several space missions […]

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 […]
