Dual - Frequency VSOP Observations of AO 0235 + 164
AO 0235+164 is a very compact, flat spectrum radio source identified as a BL Lac object at a redshift of z = 0.94. It is one of the most violently variable extragalactic objects at both optical and radio wavelengths. The radio structure of the source revealed by various ground-based VLBI observations is dominated by a nearly unresolved compact component at almost all available frequencies. Dual...
متن کاملDual frequency VSOP imaging of the jet in S 5 0836 + 710
The luminous high-redshift (z = 2.17) quasar S5 0836+710 has been observed in October 1997 with the VSOP at 1.6GHz and 5GHz. We report here a previously unpublished image made from the data at 1.6GHz and compare the structure of a relativistic jet in this quasazr at the two frequencies. We present a spectral index image tracing spectral properties of the jet up to ∼ 40 milliarcsecond distance f...
متن کاملDual frequency VLBI polarimetric observations of 3C138
We report VLBI polarimetric observations of the steep spectrum compact radio source 3C138. The relatively small range of Faraday rotation measured in the outer jet and hotspot region suggests that the jet is not being confined by a dense plasma. These results are inconsistent with the “frustrated jet” scenario and are consistent with the “young source” scenario. Evidence is given for extensive ...
متن کاملVSOP Observations of the EGRET Blazar 1633 + 382
Two high-resolution 5 GHz VSOP+VLBA images of the blazar 1633+382 reveal clear morphological change in both the bright inner east-west jet, and in the more diffuse structure further down the jet to the northwest. Here, we discuss the motion of the inner jet as traced by these VSOP images and earlier VLBA observations. The quasar 1633+382 shows a γ-ray bright blazar nucleus (Mattox et al. 1993) ...
متن کاملVSOP Monitoring of the Compact BL Lac Object AO 0235 + 164 Sándor
In 1999, the highly compact and variable BL Lac object AO 0235+164 was identified as the highest brightness temperature active galactic nucleus observed with the VLBI Space Observatory Programme (VSOP), with TB > 5.8× 1013K (Frey et al. 2000). The sub-milliarcsec radio structure of this source has been studied with dualfrequency (1.6 and 5GHz), polarization-sensitive VSOP observations during 20...
