Kavli Affiliate: Michael McDonald | First 5 Authors: Osase Omoruyi, Grant R. Tremblay, Francoise Combes, Timothy A. Davis, Michael D. Gladders | Summary: With two central galaxies engaged in a major merger and a remarkable chain of 19 young stellar superclusters wound around them in projection, the galaxy cluster SDSS J1531+3414 ($z=0.335$) offers an excellent […]
Kavli Affiliate: Marshall W. Bautz | First 5 Authors: Ayşegül Tümer, Daniel R. Wik, Gerrit Schellenberger, Eric D. Miller, Marshall W. Bautz | Summary: Observations of galaxy cluster mergers provide insights on the particle acceleration and heating mechanisms taking place within the intracluster medium. Mergers form shocks that propagate through the plasma, which result in […]
Kavli Affiliate: Herman L. Marshall | First 5 Authors: Eugene Churazov, Ildar Khabibullin, Thibault Barnouin, Niccolò Bucciantini, Enrico Costa | Summary: We report the discovery of X-ray polarization from the X-ray-bright thread/filament G0.13-0.11 in the Galactic Center region. This filament features a bright hard X-ray source, most plausibly a Pulsar Wind Nebula (PWN), and an […]

Kavli Affiliate: Sara Seager | First 5 Authors: Allyson Bieryla, George Zhou, Juliana García-Mejía, Tyler R. Farnington, David W. Latham | Summary: We report the discovery of TOI-4641b, a warm Jupiter transiting a rapidly rotating F-type star with a stellar effective temperature of 6560 K. The planet has a radius of 0.73 $R_{Jup}$, a mass […]
Kavli Affiliate: Jacqueline N. Hewitt | First 5 Authors: Geoff G. Murphy, Philip Bull, Mario G. Santos, Zara Abdurashidova, Tyrone Adams | Summary: Observations with radio arrays that target the 21-cm signal originating from the early Universe suffer from a variety of systematic effects. An important class of these are reflections and spurious couplings between […]

Kavli Affiliate: Max Tegmark | First 5 Authors: Isaac Liao, Ziming Liu, Max Tegmark, , | Summary: An essential goal in mechanistic interpretability to decode a network, i.e., to convert a neural network’s raw weights to an interpretable algorithm. Given the difficulty of the decoding problem, progress has been made to understand the easier encoding […]
Kavli Affiliate: Salvatore Vitale | First 5 Authors: Jack Heinzel, Sylvia Biscoveanu, Salvatore Vitale, , | Summary: The astrophysical formation channels of binary black hole systems predict correlations between their mass, spin, and redshift distributions, which can be probed with gravitational-wave observations. Population-level analysis of the latest LIGO-Virgo-KAGRA catalog of binary black hole mergers has […]
