We report results of a VSOP (VLBI Space Observatory Programme) observation of a high redshift quasar PKS 2215+020 (z=3.572). The ~1 milliarcsecond resolution image of the quasar reveals a prominent `core-jet' structure on linear scales from 5/h to 300/h pc ($H_0=100*h km/(s*Mpc). The brightness temperatures and sizes of bright features identified in the jet are consistent with emission from relativistic shocks dominated by adiabatic energy losses. The jet is powered by the central black hole… Expand

Radio structure of the blazar 1156 + 295 with sub-pc resolution
Aims. 1156+295 is a flat-spectrum quasar that is loud at both radio and gamma-ray wavelengths. Previous observations of the source revealed a radio morphology on pc to kpc scales consistent with aExpand
Dual-Frequency VSOP Imaging of the Jet in S5 0836+710
The luminous high-redshift (z =2 .17) quasar S5 0836+710 was observed in 1997 October with the VSOP at 1.6GHz and 5GHz. We report here a previously unpublished image made from the data at 1.6GHz, andExpand
Jets in AGN as seen with an ultimate angular resolution
Jets and cores in Active Galactic Nuclei (AGN) constitute the dominant radio structural pattern in a broad range of angular scales from hundreds of arc seconds down to sub-milliarcseconds. This briefExpand
X-Ray Jets as Cosmic Beacons
The Chandra X-Ray Observatory has proved to have the unique capability to detect jets and hot spots in quasars and radio sources. If X-rays from any of the observed objects are due to inverse ComptonExpand
Multi-frequency investigation of the parsec- and kilo-parsec-scale radio structures in high-redshift quasar PKS 1402+044
Aims. We investigate the frequency-dependent radio properties of the jet of the luminous high-redshift (z = 3.2) radio quasar PKS 1402+044 (J1405+0415) by means of radio interferometric observations.
Optical Afterglows from Cylindrical Jets of Short Gamma-Ray Bursts
Observations of extragalactic radio jets and young stellar jets show that the jets are cylindrical; i.e., they maintain a nearly constant cross section on large scales. It has been suggested that theExpand
