Precise Measurement of the Cosmic Ray Helium Spectrum above 0.1 PeV
LHAASO Collaboration, Zhen Cao, F. Aharonian +321
We report a measurement of the cosmic ray helium energy spectrum in the energy interval 0.16 -- 13~PeV, derived by subtracting the proton spectrum from the light component~(proton…
An extreme particle accelerator powered by pulsar PSR J1849-0001
The LHAASO Collaboration
Pulsar wind nebulae (PWNe) are bubbles of relativistic particles, powered by the rotational energy loss of the central pulsars. The Crab Nebula, powered by the Milky Way's most ene…
LHAASO observation of Mrk 421 during 2021 March - 2024 March: a comprehensive VHE catalog of multi-timescale outbursts and its time average behavior
The LHAASO Collaboration, Zhen Cao, F. Aharonian +321
The Large High Altitude Air Shower Observatory (LHAASO) monitors sources within its field of view for up to 7 hours daily, achieving a duty cycle exceeding 98% and an annual point-…
Deep view of Composite SNR CTA1 with LHAASO in -rays up to 300 TeV
Zhen Cao, F. Aharonian, Y. X. Bai +323
The ultra-high-energy (UHE) gamma-ray source 1LHAASO J0007+7303u is positionally associated with the composite SNR CTA1 that is located at high Galactic Latitude $b\approx 10.5^\ci…
