Shear particle acceleration is a promising candidate for the origin of extended high-energy
emission in extra-galactic jets. In this paper, we explore the applicability of a shear model to …

We present the first X-ray observation at sub-arcsecond resolution of the high-redshift (z=
6.18) radio-loud quasar CFHQS J142952+ 544717 (J1429). The∼ 100 net-count 0.3–7 keV …

The last decade has seen tremendous developments in gamma-ray astronomy with the
extragalactic sky becoming highly populated by Active Galactic Nuclei (AGNs). This brief …

Unexpectedly strong X-ray emission from extragalactic radio jets on kiloparsec scales has
been one of the major discoveries of Chandra, the only X-ray observatory capable of sub …

We present the first results of the Chandra Cool Targets (CCT) survey of the Second
Bologna Catalog (B2CAT) of powerful radio sources, aimed at investigating the extended X …

The limited angular resolution of the existing telescopes, operating in radio, optical and X-
ray wavebands, hinder the study on multi-spectral component (MSC) emissions from the …

The detection of hard X-ray spectra (spectral index< 2) from the kiloparsec-scale jet of active
galactic nuclei cannot be accounted for by the synchrotron emission mechanism from the …

Jets powered by AGN in the early Universe (z≳ 6) have the potential to not only define the
evolutionary trajectories of the first-forming massive galaxies but to enable the accelerated …

The origin of X-ray emission from the resolved kiloparsec-scale jets of many active galactic
nuclei (AGN) remains uncertain, particularly where the X-ray emission is separate from the …

ABSTRACT A comprehensive study of the nucleus and western hotspot of Pictor A is carried
out using AstroSat observations, 13 yr of Fermi, and archival Swift observations along with …
