Very high energy gamma-ray emission beyond 10 TeV from GRB 221009A
Zhen Cao, F. Aharonian, Q. An +276
The highest energy gamma-rays from gamma-ray bursts (GRBs) have important implications for their radiation mechanism. Here we report for the first time the detection of gamma-rays…
Does or did the supernova remnant Cassiopeia A operate as a PeVatron?
Zhen Cao, F. Aharonian, Q. An +276
For decades, supernova remnants (SNRs) have been considered the prime sources of Galactic Cosmic rays (CRs). But whether SNRs can accelerate CR protons to PeV energies and thus dom…
An Ultrahigh-energy -ray Bubble Powered by a Super PeVatron
The LHAASO Collaboration, Z. Cao, F. Aharonian +277
We report the detection of a -ray bubble spanning at least 100 in ultra high energy (UHE) up to a few PeV in the direction of the star-forming region Cygnus X, implyi…
Detection of the extended -ray emission around supernova remnant DA 530 with Fermi-LAT
Yuliang Xin, Xiaolei Guo
We report the extended GeV -ray emission around the high Galactic latitude supernova remnant (SNR) DA 530 with the PASS 8 data recorded by the Fermi Large Area Telescope (Fermi-…
A tera-electronvolt afterglow from a narrow jet in an extremely bright gamma-ray burst 221009A
LHAASO Collaboration
Some gamma-ray bursts (GRBs) have an afterglow in the tera-electronvolt (TeV) band, but the early onset of this afterglow has not been observed. We report observations with the Lar…
Discovery of an Extended -ray Emission around the Supernova Remnant Candidate associated with PSR J08372454
Pengfei Zhang, Yuliang Xin
Motivated by the recent discovery of a low surface brightness diffuse emission, a supernova remnant (SNR) candidate, surrounding the young pulsar PSR~J0837--2454, we carry out a li…
