July 14, 2021
Gamma-ray GroupThe LST-1 and CTA published their first Astronomer’s Telegram (ATEL) on 13 Jul 2021; 21:03 UT : “Detection of very-high-energy gamma-ray emission from BL Lac with the LST-1”
The LST-1 detected very-high-energy gamma-ray emission from BL Lacertae, an active galaxy associated with a powerful radio source found in the constellation Lacerta.
This is an achievement in proving the performance of the LST1 telescope and robustness of its analysis.
