Evidence of a Low-Energy Cutoff in the Injected Spectrum of a Pulsar Wind Nebula

Zhihong Shi, C. -Y. Ng, Niccol`o Bucciantini +5

Bow-shock pulsar wind nebulae (PWNe) are synchrotron sources formed when the outflow of supersonic pulsars is confined by the surrounding interstellar medium. These sources are dom…

Measuring Small-scale Turbulence in Supernova Remnants with Jitter Radiation

Emily Simon, Damiano Caprioli, Niccolò Bucciantini +2

Hard X-ray emission from Cas A has been attributed to jitter radiation, implying magnetic turbulence on scales near or below the ion Larmor radius. We propose these fields arise fr…

EXPO: a quantum leap in fast, wide-band X-ray polarimetry for astrophysics

Paolo Soffitta, Sebastien Guillot, Ian Hutchinson +137

The Enhanced X-ray Polarimetry Observatory (EXPO) is a mission concept proposed to ESA as an M8 candidate, with a prospective launch in 2041. Building on the scientific success of…

Population synthesis of Galactic middle-aged pulsar wind nebulae I. Detection prospects for current and future instruments

A. De Sarkar, D. F. Torres, B. Olmi +2

Pulsar wind nebulae (PWNe) constitute the largest population of Galactic very-high-energy (VHE; GeV) -ray sources and are key laboratories for studying particle accele…

A thick-shell formalism for pulsar wind nebulae based on energy conservation

N. Bucciantini, B. Olmi

One of the most powerful approaches to model the structural and spectral evolution of wind bubbles, and pulsar wind nebulae in particular, is based on the one-zone thin-shell forma…

Kes 75 with IXPE: Detection of Nebular X-ray Polarization and Change in Pulsar Lightcurve

Josephine Wong, Jack T. Dinsmore, Roger W. Romani +16

We present the first X-ray polarization measurements of the PSR/PWN complex within SNR Kes 75. Two IXPE observations were conducted in October/November 2024 a…
