We propose a method for estimating the composition, i.e. the relative amounts of leptons and protons, of extragalactic jets which exhibit Chandra - detected knots in their kpc scale jets. The method relies on measuring, or setting upper limits on, the component of the Cosmic Microwave Background (CMB) radiation that is bulk-Comptonized by the cold electrons in the relativistically flowing jet. These measurements, along with modeling of the broadband knot emission that constrain the bulk Lorentz…

Unraveling the Physics of Quasar Jets: Optical Polarimetry and Implications for the X-ray Emission Process
Since the launch of Chandra twenty years ago, one of the greatest mysteries surrounding Quasar Jets is the production mechanism for their extremely high X-ray luminosity. Two mechanisms have been
An Infrared Study of the Large-Scale Jet in Quasar PKS 1136?135
We present Spitzer IRAC imaging of the large-scale jet in the quasar PKS 1136-135 at wavelengths of 3.6 and 5.8 {micro}m, combined with previous VLA, HST, and Chandra observations. We clearly detect
Polarimetry and the High-Energy Emission Mechanisms in Quasar Jets: The Case of PKS 1136–135
Since the discovery of kiloparsec-scale X-ray emission from quasar jets, the physical processes responsible for their high-energy emission have been poorly defined. A number of mechanisms are under
Spitzer IRAC Imaging of the Relativistic Jet from Superluminal Quasar PKS 0637?752
Emission from the relativistic jet located hundreds of kiloparsecs from the core of the superluminal quasar PKS 0637-752 was detected at 3.6 and 5.8 μm with the Infrared Array Camera (IRAC) on the
Constraints on the Low-Energy Cutoff in the Electron Distribution of the PKS 0637-752 Jet
We reanalyze the Chandra ACIS spectrum of the kpc-scale jet in PKS 0637-752 to investigate the possible low-energy cutoff in the relativistic electron spectrum producing the nonthermal radiation in
Circumnuclear Dust in AP Librae and the Source of Its VHE Emission
The broad high-energy spectral component in blazars is usually attributed to various inverse Compton scattering processes in the relativistic jet, but has not been clearly identified in most cases
Blazar jets launched with similar energy per baryon, independently of their power
The most extreme active galactic nuclei (AGN) are the radio active ones whose relativistic jet propagates close to our line of sight. These objects were first classified according to their emission
HUBBLE SPACE TELESCOPE OBSERVATIONS OF THE QUASAR PKS 0637-752: EQUIPARTITION ELECTRON-PROTON JET FROM THE MOST COMPLETE SPECTRAL COVERAGE TO DATE
We present new Near-Infrared Camera and Multi-Object Spectrometer and attitude control system observations of the quasar jet PKS 0637-752, and we use them, together with existing multiwavelength
Minute-timescale Variability in the X-ray Emission of the Highest Redshift Blazar
We report on two Chandra observations of the quasar PSO J0309+27, the most distant blazar observed so far (z = 6.1), performed eight months apart, in 2020 March and November. Previous Swift-XRT

The X-Ray Jet of PKS 0637–752: Inverse Compton Radiation from the Cosmic Microwave Background?
We propose that the X-ray emission detected by Chandra from the 100 kpc-scale jet of PKS 0637-752 is produced through inverse Compton scattering of the cosmic microwave background (CMB). We analyze
