Ultra-high-energy γ-ray emission associated with the tail of a bow-shock pulsar wind nebula [PDF]

The Innovation
In this study, we present a comprehensive analysis of an unidentified point-like ultra-high-energy (UHE) γ-ray source, designated as 1LHAASO J1740+0948u, situated in the vicinity of the middle-aged pulsar PSR J1740+1000.

Determination of X-ray pulsar geometry with IXPE polarimetry [PDF]

Nature Astronomy, 2022
Using observations of X-ray pulsar Hercules X-1 by the Imaging X-ray Polarimetry Explorer we report a highly significant (>17σ) detection of the polarization signal from an accreting neutron star. The observed degree of linear polarization of ~10% is far
