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…

VHE -ray observations of bright BL Lacs with the Large-Sized Telescope prototype (LST-1) of the CTAO

The CTAO-LST Project, :, K. Abe +331

Cherenkov Telescope Array Observatory (CTAO) is the next-generation ground-based gamma-ray observatory operating in the energy range from 20 GeV up to 300 TeV, with two sites in La…

The electron temperature distribution and the high ionization just behind the shock in the Cygnus Loop

Masahiro Ichihashi, Aya Bamba, Dai Tateishi +6

The physical processes behind astrophysical collisionless shocks, such as thermal relaxation and ionization after shock passage, remain poorly understood. To investigate these proc…

XRISM Observations of Cassiopeia A: Overview, Atomic Data, and Spectral Models

Paul Plucinsky, Manan Agarwal, Liyi Gu +15

Cassiopeia A (Cas A) is the youngest known core-collapse supernova remnant (SNR) in the Galaxy and is perhaps the best-studied SNR in X-rays. Cas A has a line-rich spectrum dominat…

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…

Mapping Cassiopeia A's silicon/sulfur Doppler velocities with XRISM-Resolve

Jacco Vink, Manan Agarwal, Aya Bamba +22

Young supernova remnants (SNRs) provide crucial insights into explosive nucleosynthesis products and their velocity distribution soon after the explosion. However, these velocities…

Measuring the asymmetric expansion of the Fe ejecta of Cassiopeia A with XRISM/Resolve

Aya Bamba, Manan Agarwal, Jacco Vink +24

The expansion structure of supernova remnants (SNRs) is important for understanding not only how heavy elements are distributed into space, but also how supernovae explode. The eje…

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…
