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…

LST-1 follow-up of the exceptionally bright gamma-ray burst GRB 221009A

Arnau Aguasca-Cabot, Alessandro Carosi, Alice Donini +6

On 9 October 2022, the brightest gamma-ray burst (GRB) ever recorded (GRB 221009A) was detected. Its remarkably bright emission, partially due to its close distance to Earth ($z\si…

Identification of Noise-Associated Glitches in KAGRA O3GK with Hveto

T. Akutsu, M. Ando, M. Aoumi +148

Transient noise ("glitches") in gravitational wave detectors can mimic or obscure true signals, significantly reducing detection sensitivity. Identifying and excluding glitch-conta…

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…
