Cat-Tails for Two Cat-Tails for Two Cat-Tails for Two is a 1953 (1961 Blue Ribbon Re-issue) Warner Bros. "Merrie Melodies" cartoon, directed by Robert McKimson and written by Tedd Pierce starring Bennie the fat cat and George. It was animated in 1952. Voices by Mel Blanc and music by Carl Stalling. It was the first appearance of Speedy Gonzales, in a prototype form. Because this cartoon's rendition of Speedy Gonzales looked rather coarse, they redesigned him for future cartoon releases. The two cats pursuing Speedy in "Cat-Tails for Two" are the slow-witted (and injury-causing) Benny and the fully functioning but unfortunate George, both
Sombrero Galaxy when high velocity electrons oscillate as they pass through regions with strong magnetic fields. This emission is quite common for active galactic nucleus. Although radio synchrotron radiation may vary over time for some active galactic nucleus, the luminosity of the radio emission from the Sombrero Galaxy varies only 10–20%. In 2006, two groups published measurements of the terahertz radiation from the nucleus of the Sombrero Galaxy at a wavelength of . This terahertz radiation was found not to originate from the thermal emission from dust (which is commonly seen at infrared and submillimeter wavelengths), synchrotron radiation (which is commonly seen
