Detection of the distant quasar OP 313 with the first Large-Sized Telescope of CTAO
K. Abe, S. Abe, J. Abhir +412
In December 2023, the Large-Sized Telescope prototype (LST-1) detected for the first time VHE -ray emission from the FSRQ OP~313 becoming the furthest blazar ever observed at V…
GRB 221009A: Observations with LST-1 of CTAO and Implications for Structured Jets in Long Gamma-Ray Bursts
LST Collaboration, K. Abe, S. Abe +328
GRB 221009A is the brightest gamma-ray burst (GRB) observed to date. Extensive observations of its afterglow emission across the electromagnetic spectrum were performed, providing…
CTAO LST-1 observations of magnetar SGR 1935+2154: Deep limits on sub-second bursts and persistent tera-electronvolt emission
K. Abe, S. Abe, A. Abhishek +333
The Galactic magnetar SGR 1935+2154 has exhibited prolific high-energy (HE) bursting activity in recent years. Investigating its potential tera-electronvolt counterpart could provi…
Detection of the Geminga pulsar at energies down to 20 GeV with the LST-1 of CTAO
The CTAO-LST Project, :, K. Abe +331
Geminga is the third gamma-ray pulsar firmly detected by imaging atmospheric Cherenkov telescopes (IACTs) after the Crab and the Vela pulsars. Most of its emission is expected at t…
