MonographDOI

Science with the Cherenkov Telescope Array

B. S. Acharya, +580 more
TL;DR: The Cherenkov Telescope Array (CTA) as mentioned in this paper is the major global observatory for very high energy gamma-ray astronomy over the next decade and beyond, covering a huge range in photon energy from 20 GeV to 300 TeV.
Journal ArticleDOI

On the origin of asymmetries in bilateral supernova remnants

TL;DR: In this article, the morphology of bilateral supernova remnants (BSNRs) observed in the radio band is determined mainly either by a non-uniform interstellar medium (ISM) or a nonuniform ambient magnetic field.
Journal ArticleDOI

Thermal emission, shock modification, and X-ray emitting ejecta in SN 1006

TL;DR: In this paper, the contribution of thermal and non-thermal emission to the X-ray spectrum at the rim of the supernova remnant to study how the acceleration processes affect the Xray emitting plasma.
Journal ArticleDOI

Role of Ejecta Clumping and Back-reaction of Accelerated Cosmic Rays in the Evolution of Type Ia Supernova Remnants

TL;DR: In this article, the role played by initial clumping of ejecta and by efficient acceleration of cosmic rays (CRs) in determining the density structure of the post-shock region of a Type Ia supernova remnant (SNR) through detailed three-dimensional MHD modeling.
Journal ArticleDOI

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

Ayan Acharyya, +456 more
TL;DR: In this paper, the authors 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 signal from pair-annihilating dark matter particles in the region around the Galactic centre.
