IXPE View of the Crab Pulsar Following the 2025 July 17 and August 6 Glitches

The Astrophysical Journal
The Crab pulsar experienced two relatively small glitches separated by only 20 days in 2025 September and October. Imaging X-ray Polarimetry Explorer (IXPE) observed the source twice, with delay times since the glitch epoch ranging between 35 and 75 days,

Magnetic Flux Tubes Illuminated by Pulsar Winds

The Astrophysical Journal
Observations of linear structure connecting pulsars to gamma-ray halos reveal injection of TeV electrons into the interstellar medium (ISM). In some cases, this could be attributed to nearly scattering-free electron transport along large-scale magnetic ...

Recent progress on anomalous X-ray pulsars

Astrophysics and Space Science, 2007
I review recent observational progress on Anomalous X-ray Pulsars, with an emphasis on timing, variability, and spectra. Highlighted results include the recent timing and flux stabilization of the notoriously unstable AXP 1E 1048.1-5937, the remarkable glitches seen in two AXPs, the newly recognized variety of AXP variability types, including outbursts,

Investigating the emission signatures of pulsar halo candidate HESS J1813-126

Astronomy & Astrophysics
Context. Extended gamma-ray sources surrounding middle-aged pulsars, primarily observed at teraelectronvolt energies, have been interpreted as pulsar halos, where relativistic e± diffuse into the interstellar medium and produce inverse-Compton (IC ...

High-resolution Radio Study of Pulsar Wind Nebula MSH 15–52 and Supernova Remnant RCW 89

The Astrophysical Journal
We present high-resolution radio observations of the pulsar wind nebula (PWN) MSH 15–5 2 , which is renowned for its distinctive handlike shape, and its associated supernova remnant RCW 89. Using the Australia Telescope Compact Array, we obtained 3 and 6
