All-sky search for individual Primordial Black Hole bursts with LHAASO
Zhen Cao, F. Aharonian, Y. X. Bai +311
Primordial Black Holes~(PBHs) are hypothetical black holes with a wide range of masses that formed in the early universe. As a result, they may play an important cosmological role…
Broadband -ray spectrum of supernova remnant Cassiopeia A
Zhen Cao, F. Aharonian, Y. X. Bai +311
The core-collapse supernova remnant (SNR) Cassiopeia A (Cas A) is one of the brightest galactic radio sources with an angular radius of 2.5 $\arcmin$. Although no extension…
Detection of two TeV gamma-ray outbursts from NGC 1275 by LHAASO
Zhen Cao, F. Aharonian, Axikegu +275
The Water Cherenkov Detector Array (WCDA) is one of the components of Large High Altitude Air Shower Observatory (LHAASO) and can monitor any sources over two-thirds of the sky for…
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…
