Prospects for -ray observations of the Perseus galaxy cluster with the Cherenkov Telescope Array

The Cherenkov Telescope Array Consortium, :, K. Abe +564

Galaxy clusters are expected to be dark matter (DM) reservoirs and storage rooms for the cosmic-ray protons (CRp) that accumulate along the cluster's formation history. Accordingly…

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…

astro-ph.HE2025

Constraining the TeV gamma-ray emission of SN 2024bch, a possible type IIn-L from a red supergiant progenitor. Multiwavelength observations and analysis of the progenitor

The CTAO-LST Project, :, K. Abe +332

We present very high-energy optical photometry and spectroscopic observations of SN 2024bch in the nearby galaxy NGC 3206 (\sim 20 Mpc). We used gamma-ray observations performed wi…

astro-ph.HE2024

A new method of reconstructing images of gamma-ray telescopes applied to the LST-1 of CTAO

CTA-LST Project, :, K. Abe +305

Imaging atmospheric Cherenkov telescopes (IACTs) are used to observe very high-energy photons from the ground. Gamma rays are indirectly detected through the Cherenkov light emitte…

astro-ph.HE2024

A detailed study of the very-high-energy Crab pulsar emission with the LST-1

CTA-LST Project, :, K. Abe +294

Context: There are currently three pulsars firmly detected by imaging atmospheric Cherenkov telescopes (IACTs), two of them reaching TeV energies, challenging models of very-high-e…

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…
