Informations-/Cybersecurity-Standards,On the subject of radiogalaxies my most vivid reminiscence is of an afternoon in Santa Barbara Street with a marvellous meeting with Baade and Minkowski where they told me that they had discovered that Cygnus A had been identified with a faint galaxy.

Informationssuche und Online Word-of-MouthRecent observations of Cygnus A with the Hat Creek interferometer at 86.2 GHz limit the spectral curvature of the hotspots and show that the diffuse lobe emission has a spectral index of about 1.5. The central component is, at most, weakly variable and its spectrum shows a distinct break to a spectral index near 0.65 at about 20 GHz.

VLA and Optical Mapping of the Quasar PKS 0812+020,Observations are reported of the remarkable object PKS 0812+020, the first quasar found to have optical emission in one of its radio lobes. A distinct radio jet is also seen, and there is radio and optical evidence that the quasar is near the center of a galaxy cluster.
