Recent highlights from the LHAASO observatory
The Large High Altitude Air Shower Observatory (LHAASO), located in China at 4410m above sea level, is a complex of extensive air shower (EAS) detector array. Utilizing different detection techniques, LHAASO surveys the entire northern gamma-ray and cosmic-ray sky with a wide energy range from sub-TeV to PeV energies.
The full array of LHAASO has been operational since July 2021. With data collected with a partial array in 2020, LHAASO found a dozen UHE gamma-ray sources, with an unprecedented highest photon energy of 1.4 ± 0.13 PeV. These findings confirmed the existence of PeV particle accelerators in our Galaxy and opened up an era of ultra-high-energy gamma-ray astronomy.
In this talk, I will summarize the status of the LHAASO experiment and present recent highlights from the LHAASO observatory.
