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…
When will T Coronae Borealis next erupt as a nova? Constraints from recurrence, orbital phase, and accretion-state evolution
Songpeng Pei, Xiaowan Zhang, Renzhi Su +6
The paper combines historical eruption intervals, orbital phase information, and recent accretion‑state changes to give conditional probabilities and monitoring windows for the nex…
FAST Discovery of Jy Radio Pulsations from PSR J2238+5903, Providing a DM Distance Anchor for the Candidate TeV Halo 1LHAASO J2238+5900
Jianli Zhang, Hui Zhu, Guanhong Lin +10
We report the first detection of radio pulsations from PSR J2238+5903, a gamma-ray pulsar spatially coincident with the extended TeV source 1LHAASO J2238+5900. Our 3000 s FAST L-ba…
Lack of Significant Orbital-Phase Locking in the Active Phases of the Recurrent Nova T CrB
Songpeng Pei, Xiaowan Zhang, Renzhi Su +6
T Coronae Borealis (T CrB) is a symbiotic recurrent nova (RN) that exhibits both nova eruptions and long-term active phases resembling superoutbursts and normal outbursts. Motivate…
Diffuse gamma-ray emission in the vicinity of open cluster Berkeley 87
Ziwei Ou, Xiaolong Yang
We report the detection of diffuse gamma-ray emission toward the young massive star cluster Berkeley 87 using Fermi data. The emission has an angular extension of 0.36 degree and a…
Diffuse gamma-ray emissions around the stellar cluster Berkeley 59
Ziwei Ou, Xiaolong Yang, Songpeng Pei
We report a detailed analysis on the young stellar cluster Berkeley 59 using Fermi-LAT. Using up-to-date source catalog and background models, we found significant extended GeV emi…
