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 filament. G0.13-0.11 in the Galactic center (GC) region. This filament features a bright, hard X-ray source that is most plausibly a pulsar wind nebula […]

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 […]
Kavli Affiliate: Michael Fausnaugh | First 5 Authors: Hali Huang, Daniel Muthukrishna, Prajna Nair, Zimi Zhang, Michael Fausnaugh | Summary: Astronomical transients, such as supernovae and other rare stellar explosions, have been instrumental in some of the most significant discoveries in astronomy. New astronomical sky surveys will soon record unprecedented numbers of transients as sparsely […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Zhijie Zhang, Xiaoxia Zhang, Hui Li, Taotao Fang, Qingzheng Yu | Summary: Milky Way-type galaxies are surrounded by a warm-hot gaseous halo containing a considerable amount of baryons and metals. The kinematics and spatial distribution of highly-ionized ion species such as ion{O}{6} can be significantly affected by […]
Kavli Affiliate: Herman L. Marshall | First 5 Authors: Philip Kaaret, Riccardo Ferrazzoli, Stefano Silvestri, Michela Negro, Alberto Manfreda | Summary: How astrophysical systems translate the kinetic energy of bulk motion into the acceleration of particles to very high energies is a pressing question. SS 433 is a microquasar that emits TeV gamma-rays indicating the […]
Kavli Affiliate: Saul Rappaport | First 5 Authors: Valencia Zhang, Saul Rappaport, Rahul Jayaraman, Donald W. Kurtz, Gerald Handler | Summary: We have discovered a $delta$ Scuti pulsator in a tight binary (P = 1.053 d) with nine pulsation modes whose frequencies are between 38 and 56 d$^{-1}$. Each of these modes exhibits amplitude modulations […]
