Recent observations of a few young pulsar wind nebulae (PWNe) have revealed their morphologies in some detail. Given the availability of spatio-spectral-temporal data, we use our m…
A Self-regulated Stochastic Acceleration Model of Pulsar Wind Nebulae
Shuta J. Tanaka, Wataru Ishizaki
Pulsar wind nebulae (PWNe) are clouds of the magnetized relativistic electron/positron plasma supplied from the central pulsar. However, the number of radio-emitting particles insi…
Detection of the 2021 Outburst of RS Ophiuchi with the LST-1
Yukiho Kobayashi, Arnau Aguasca-Cabot, María Isabel Bernardos Martín +2
Novae are luminous explosions in close binaries which host a white dwarf and a companion donor star. They are triggered by a thermonuclear runaway when the white dwarf accretes a c…
Imaging Atmospheric Cherenkov Telescopes pointing determination using the trajectories of the stars in the field of view

Dark matter searches in dwarf spheroidal galaxies with the Cherenkov Telescope Array
Francesco Gabriele Saturni, Michele Doro, Aldo Morselli +1
Dark matter (DM) is one of the major components in the Universe. However, at present its existence is still only inferred through indirect astronomical observations. DM particles c…
Testing a stochastic acceleration model of pulsar wind nebulae: Early evolution of a wind nebula associated with SN 1986J
