Detection of the Geminga pulsar at energies down to 20 GeV with the LST-1 of CTAO

Andrii Neronov, Oleg Kalashev, Volodymyr Savchenko

Context. 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 tens of giga-electronvolts, and, out of the planned telescopes of th ...

GRB 221009A: Observations with LST-1 of CTAO and Implications for Structured Jets in Long Gamma-Ray Bursts

Andrii Neronov, Oleg Kalashev, Volodymyr Savchenko

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 the first strong evidence of a jet with a nontrivial angular structure in a ...

Detection of RS Oph with LST-1 and modelling of its HE/VHE gamma-ray emission

Andrii Neronov, Oleg Kalashev, Volodymyr Savchenko

Context. The recurrent nova RS Ophiuchi (RS Oph) underwent a thermonuclear eruption in August 2021. In this event, RS Oph was detected by the High Energy Stereoscopic System (H.E.S.S.), the Major Atmospheric Gamma Imaging Cherenkov (MAGIC), and the first L ...
