Search for Axion-Like Particles from Nearby Pre-Supernova Stars

Saurabh Mittal, Thomas Siegert, Francesca Calore +7

Axion-like particles (ALPs) are hypothetical pseudoscalar bosons that arise in many extensions of the Standard Model and are well-motivated dark matter candidates. Nearby massive s…

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…

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

CTA-LST Project, :, K. Abe +316

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…
