Letter to the Editor III Zw 2, the first superluminal jet in a Seyfert galaxy
So far all relativistically boosted jets with superluminal motion have only been detected in typical radio galaxies with early type host galaxies. We have now discovered superluminal motion in the Seyfert I galaxy III Zw 2, classified as a spiral. Superluminal motion was first inferred from the spectral evolution of the source and then confirmed by VLBI observations. The lower limit for the app...

متن کاملA major radio outburst in III Zw 2 with an extremely inverted ,
III Zw 2 is a spiral galaxy with an optical spectrum and faint extended radio structure typical of a Seyfert galaxy, but also with an extremely variable, blazar-like radio core. We have now discovered a new radio are where the source has brightened more than twenty-fold within less than two years. A broad-band radio spectrum between 1.4 and 666 GHz shows a textbook-like synchrotron spectrum pea...
متن کاملThe Extreme-ultraviolet Continuum of a Strong Stellar Flare
We present the serendipitous detection of an extreme-ultraviolet flare on EUVE J0613 23.9B. The flare showed over a 200-fold increase above the quiescent emission in the DS/Lexan 60–200 Å wavelength band. Optical spectroscopy revealed that the event was associated with an active dM3.5e star. The EUVE spectra are dominated by emission lines formed at temperatures in excess of 10 K. The observati...
متن کاملExtreme dentoalveolar compensation in the treatment of Class III malocclusion.
The orthodontic treatment of an adult patient with a skeletal Class III malocclusion, increased anterior facial height, negative overjet, and bilateral posterior crossbite is presented. Treatment options included mandibular first premolar or third molar extractions with dentoalveolar compensation or combined surgical-orthodontic treatment. Mandibular third molar extraction with dentoalveolar co...
