Sunyaev-Zel’dovich effect and X-ray scaling relations of galaxies, groups and clusters in the IllustrisTNG simulations

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 […]

A Taxonomy for the Configurations of Quadruply Lensed Quasars

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 […]

There and back again: understanding the critical properties of backsplash galaxies

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 […]

Towards Understanding Grokking: An Effective Theory of Representation Learning

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 […]

SRGA J181414.6-225604: A new Galactic symbiotic X-ray binary outburst triggered by an intense mass loss episode of a heavily obscured Mira variable

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 […]
