Escape of cosmic rays from perpendicular shocks in the interstellar magnetic field

Shoma F. Kamijima, Yutaka Ohira

We investigate the escape process from a perpendicular shock region of a spherical shock in the interstellar medium (ISM). The diffusive shock acceleration in the perpendicular sho…

The Biermann battery driven by a streaming plasma

Yutaka Ohira

The Biermann battery is a promising generation mechanism of a seed magnetic field in the universe. We propose a new driving mechanism for the Biermann battery in an inhomogeneous p…

Off-axis jet scenario for early afterglow emission of low-luminosity gamma-ray burst GRB 190829A

Yuri Sato, Kaori Obayashi, Ryo Yamazaki +2

Recently, ground-based Imaging Atmospheric Cherenkov Telescopes have reported the detection of very-high-energy (VHE) gamma-rays from some gamma-ray bursts (GRBs). One of them, GRB…

Sensitivity of the Cherenkov Telescope Array for probing cosmology and fundamental physics with gamma-ray propagation

The Cherenkov Telescope Array Consortium, :, H. Abdalla +496

The Cherenkov Telescope Array (CTA), the new-generation ground-based observatory for -ray astronomy, provides unique capabilities to address significant open questions in astrop…

Sensitivity of the Cherenkov Telescope Array to a dark matter signal from the Galactic centre

The Cherenkov Telescope Array Consortium, :, A. Acharyya +449

We provide an updated assessment of the power of the Cherenkov Telescope Array (CTA) to search for thermally produced dark matter at the TeV scale, via the associated gamma-ray sig…

Study on the escape timescale of high-energy particles from supernova remnants through thermal X-ray properties

Hiromasa Suzuki, Aya Bamba, Ryo Yamazaki +1

In this decade, GeV/TeV gamma-ray observations of several supernova remnants (SNRs) have implied that accelerated particles are escaping from their acceleration sites. However, whe…
