PWN-powered Galactic Center X-ray filament G0.13-0.11: Proof of the synchrotron nature by IXPE

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 […]

Bayesian estimation of cross-coupling and reflection systematics in 21cm array visibility data

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 […]

Generating Interpretable Networks using Hypernetworks

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 […]

Probing Correlations in the Binary Black Hole Population with Flexible Models

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 […]

X-ray Polarization of the Eastern Lobe of SS 433

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 […]
