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…
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…
Peculiar disk behaviors of the black hole candidate MAXI J1348-630 in the hard state observed by Insight-HXMT and Swift
W. Zhang, L. Tao, R. Soria +93
We present a spectral study of the black hole candidate MAXI J1348-630 during its 2019 outburst, based on monitoring observations with Insight-HXMT and Swift. Throughout the outbur…
The observation of the Crab Nebula with LHAASO-KM2A for the performance study
F. Aharonian, Q. An, Axikegu +246
As a sub-array of the Large High Altitude Air Shower Observatory (LHAASO), KM2A is mainly designed to cover a large fraction of the northern sky to hunt for gamma-ray sources at en…
A variable ionized disk wind in the black-hole candidate EXO 1846-031
Yanan Wang, Long Ji, Javier A. Garcia +88
After 34 years, the black-hole candidate EXO 1846-031 went into outburst again in 2019. We investigate its spectral properties in the hard intermediate and the soft states with NuS…
The evolution of the broadband temporal features observed in the black-hole transient MAXI J1820+070 with Insight-HXMT
Yanan Wang, Long Ji, S. N. Zhang +117
We study the evolution of the temporal properties of MAXI 1820+070 during the 2018 outburst in its hard state from MJD 58190 to 58289 with Insight-HXMT in a broad energy band 1-150…
Crab Nebula: five-year observation with ARGO-YBJ
YBJ Collaboration
The ARGO-YBJ air shower detector monitored the Crab Nebula gamma ray emission from 2007 November to 2013 February. The integrated signal, consisting of 3.3 10 ev…
Search for GeV Gamma Ray Bursts with the ARGO-YBJ Detector: Summary of Eight Years of Observations
B. Bartoli, P. Bernardini, X. J. Bi +78
The search for Gamma Ray Burst (GRB) emission in the energy range 1-100 GeV in coincidence with the satellite detection has been carried out using the Astrophysical Radiation with…
Long-term Monitoring on Mrk 501 for Its VHE gamma Emission and a Flare in October 2011
YBJ Collaboration, B. Bartoli, P. Bernardini +101
As one of the brightest active blazars in both X-ray and very high energy -ray bands, Mrk 501 is very useful for physics associated with jets from AGNs. The ARGO-YBJ experiment…
