X - rays from the jet in 3 C 273 : clues from the radio – optical spectra
نویسندگان
چکیده
Using new deep VLA and HST observations of the large-scale jet in 3C 273 matched to 0. ′′ 3 resolution, we have detected excess near-ultraviolet emission (λ 300 nm) above a synchrotron cutoff spectrum accounting for the emission from radio through optical (λλ3.6 cm–620 nm). This necessitates a two-component model for the emission. The radio–optical–X-ray spectral energy distributions suggest a common origin for the UV excess and the X-rays from the jet.

New Chandra Observations of the Jet in 3c273. I. Softer X-ray than Radio Spectra and the X-ray Emission Mechanism
The jet in 3C273 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 observations of this jet and analyse the spectral properties of the jet emission from radio through X-rays. We find that the X-ray spectra are significantly softer than the radio spectra in all regions...
متن کاملThe multiwavelength variability of 3 C 273
Aims. We present an update of the 3C 273’s database hosted by the ISDC, completed with data from radio to gamma-ray observations over the last 10 years. We use this large data set to study the multiwavelength properties of this quasar, especially focussing on its variability behaviour. Methods. We study the amplitude of the variations and the maximum variability time scales across the broad-ban...
متن کاملSpectra of black-hole binaries in the low/hard state: from radio to X-rays
We propose a jet model for the low/hard state of Galactic black-hole X-ray sources that can explain the energy spectra from radio to X-rays. The model assumes that i) there is a magnetic field along the axis of the jet; ii) the electron density in the jet drops inversely proportional to distance; and iii) the electrons in the jet follow a power law distribution function. We have performed Monte...
متن کامل1 X - Ray Emission from the 3 C 273
We present results from four recent Chandra monitoring observations of the jet in 3C 273 using the ACIS detector, obtained between November 2003 and July 2004. We find that the X-ray emission comes in two components: unresolved knots that are smaller than the corresponding optically emitting knots and a broad channel that is about the same width as the optical interknot region. We compute the j...
متن کاملMultifrequency Radiation of Extragalactic Large-Scale Jets
Large-scale extragalactic jets, observed to extend from a few to a few hundred kiloparsecs from active galactic nuclei, are now studied over many decades in frequency of electromagnetic spectrum, from radio until (possibly) TeV γ rays. For hundreds of known radio jets, only about 25 are observed at optical frequencies. Most of them are relatively short and faint, with only a few exceptions, lik...
