Anisotropic Particle Transport from a Pulsar Wind Nebula Revealed by Einstein Probe and LHAASO

Zhen Cao, F. Aharonian, Y. X. Bai +339

Pulsar wind nebulae (PWNe) are major cosmic ray accelerators, yet the mechanisms transporting high-energy particles into the interstellar medium remain elusive. Building on the LHA…

X-rays breaking out of pre-explosion ejecta mark a supernova's first light

Weimin Yuan, Qiu-Ju Huang, Jin-Ping Zhu +130

Massive stars die as core-collapse supernovae, whose optical light emerges days after the implosion. Theory predicts that the initial collapse-driven shock, upon breaking through t…

Discovery of EP J175257.3-351923 as a Candidate Black Hole Low-Mass X-ray Binary

G. L. Huang, Q. C. Zhao, L. Tao +30

We report the discovery of a new X-ray transient, EP J175257.3-351923 (EP250916a), by the Einstein Probe (EP) near the Galactic plane. The outburst lasted for at least 250\,days, r…

Magnetar emergence in a peculiar gamma-ray burst from a compact star merger

H. Sun, C. -W. Wang, J. Yang +42

The central engine that powers gamma-ray bursts (GRBs), the most powerful explosions in the universe, is still not identified. Besides hyper-accreting black holes, rapidly spinning…
