We have performed infrared imaging of the jet of the quasar 3C 273 at wavelengths of 3.6 and 5.8 μm with the Infrared Array Camera (IRAC) on the Spitzer Space Telescope. When combined with the radio, optical, and X-ray measurements, the IRAC photometry of the X-ray-bright jet knots clearly shows that the optical emission is dominated by the high-energy emission component of the jet, not by the radio synchrotron component, as had been assumed to date. The high-energy component, represented by a…

THE INFRARED JET IN 3C 31

We report the detection of infrared emission from the jet of the nearby Fanaroff–Riley type I radio galaxy 3C 31. The jet was detected with the IRAC instrument on Spitzer at 4.5 μm, 5.8 μm, and 8.0

The jet in 3C 273 is a high-power quasar jet with radio, optical, and X-ray emission, whose size and brightness allow a detailed study of the emission processes acting in it. We present deep Chandra

A Multi-band Study of the Remarkable Jet in Quasar 4C+19.44

We present arcsecond-resolution data in the radio, IR, optical, and X-ray for 4C+19.44 (=PKS 1354+195), the longest and straightest quasar jet with deep X-ray observations. We report results from

Hubble Space Telescope far-ultraviolet imaging of the jet in 3C 273 : a common emission component from optical to X-rays

We present far-ultraviolet (far-UV) observations at ∼150 nm of the jet of quasar 3C 273 obtained with the Advanced Camera for Surveys (ACS) Solar Blind Channel onboard the Hubble Space Telescope.

Multiwavelength variability analysis of the blazar 3C 273

We analysed the broadband light curves of the flat spectrum radio quasar (FSRQ) 3C 273 between September 2008 and August 2012. The discrete correlation function (DCF) probed the correlation between

PROTON SYNCHROTRON RADIATION FROM EXTENDED JETS OF PKS 0637–752 AND 3C 273

Many powerful radio quasars are associated with large-scale jets, exhibiting bright knots as shown by high-resolution images from the Hubble Space Telescope (HST) and the Chandra X-ray Observatory.

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

Deep Chandra and Multicolor HST Observations of the Jets of 3C 371 and PKS 2201+044

This paper presents multiwavelength imaging and broadband spectroscopy of the relativistic jets in the two nearby radio galaxies 3C 371 and PKS 2201+044, acquired with Chandra, HST, VLA, and MERLIN.

Jet Radiation Properties of 4C +49.22: from the Core to Large-scale Knots

4C +49.22 is a γ-ray flat-spectrum radio quasar with a bright and knotty jet. We investigate the properties of the core and large-scale knots by using their spectral energy distributions (SEDs).
