Kavli Affiliate: Michael Fausnaugh | First 5 Authors: Jason T. Hinkle, Christopher S. Kochanek, Benjamin J. Shappee, Patrick J. Vallely, Katie Auchettl | Summary: We analyze high-cadence data from the Transiting Exoplanet Survey Satellite (TESS) of the ambiguous nuclear transient (ANT) ASASSN-18el. The optical changing-look phenomenon in ASASSN-18el has been argued to be due to […]

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Ana-Roxana Pop, Lars Hernquist, Daisuke Nagai, Rahul Kannan, Rainer Weinberger | Summary: Observable thermodynamical properties of the intracluster medium (ICM) reflect the complex interplay between AGN feedback and the gravitational collapse of haloes. Using the large volume TNG300 simulation of the IllustrisTNG project we provide predictions for […]
Kavli Affiliate: Paul L. Schechter | First 5 Authors: Paul L. Schechter, , , , | Summary: A simple, novice-friendly scheme for classifying the image configurations of quadruply lensed quasars is proposed. With only six classes, it is intentionally coarse-grained. Readers are invited to test drive the scheme on a sample of 12 quadruply lensed […]

Schechter, , , , | Summary: A simple, novice-friendly scheme for classifying the image configurations of quadruply lensed quasars is proposed. With only six classes, it is intentionally coarse-grained. It focuses on the kitelikeness and circularity of these configurations, or the absence thereof. Other […]
Kavli Affiliate: Frank Wilczek | First 5 Authors: Frank Wilczek, , , , | Summary: C. N. Yang’s ideas about local gauge symmetry and non-integrable phases have been enormously fertile sources of inspiration in fundamental physics and in the quantum theory of matter. They also arise naturally in describing the dynamics of deformable bodies. Here […]
Kavli Affiliate: Mark Vogelsberger | 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 outside as they move towards the apocenter of their orbit. The kinematic properties of these galaxies are well understood, thanks […]

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 […]
