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…
Magnetic field generation by an inhomogeneous return current
Yutaka Ohira
A new generation mechanism of the magnetic field in an inhomogeneous collisionless plasma with a beam component is proposed. We show that even though the current and charge neutral…
Fast Particle Acceleration at Perpendicular Shocks with Uniform Upstream Magnetic Field and Strong Downstream Turbulence
Shoma F. Kamijima, Yutaka Ohira, Ryo Yamazaki
The shock waves produce relativistic particles via the diffusive shock acceleration (DSA) mechanism. Among various circumstances, fast acceleration has been expected for perpendicu…
Particle acceleration in a shock wave propagating to an inhomogeneous medium
Shota L. Yokoyama, Yutaka Ohira
We investigate effects of upstream density fluctuations on the diffusive shock acceleration by Monte Carlo simulations. The simulations show that particles are reaccelerated in the…
