Owens Valley Radio Observatory
Owens Valley Radio Observatory (OVRO) is a radio astronomy observatory located near Big Pine, California (USA) in Owens Valley. It lies east of the Sierra Nevada approximately north of Los Angeles and southeast of Bishop. It was established in 1958, and is owned and operated by the California Institute of Technology (Caltech).
One of the ten dish-antenna radiotelescope systems of the Very Long Baseline Array is immediately adjacent to, but not part of, the Owens Valley observatory.
==About==
The Owens Valley Radio Observatory (OVRO), the largest university-operated radio observatory, came to life in the late 1940s through the influence of three individuals: Lee DuBridge, president of Caltech; Robert Bacher, chairman of the Division of Physics, Mathematics and Astronomy; and Jesse Greenstein, professor of astrophysics. In 1954, Caltech occupied a central position in the American radio astronomy program. John Bolton and Gordon Stanley, two respected Australian astronomers, joined the Caltech faculty in order to undertake the construction of large dishes. In 1956 the first radio telescope, a 32-foot antenna, was erected on Palomar Mountain. It was dismantled in 1958 and transferred to the Owens Valley site. At the same time, two 90-foot (27-meter) telescopes were completed. Ten years later, an even bigger antenna, a 130-foot (40-meter) dish was finished. It was originally built to study radio galaxies but is now used to look at the sun's magnetic field. The last major instrument at the observatory is the millimeter-wave array. It consists of six 34-foot (10.4-meter) dishes (also called Leighton's dishes).
OVRO, owned by Caltech, is one of the biggest radio observatories owned by a university.〔 OVRO uses its telescopes and other instruments (listed below) to improve on the locations of radio sources in the sky, as well as to study hydrogen clouds within the Milky Way.〔 The research that takes place at the observatory includes studies on blazars, the cosmic microwave background, and star-formation, and this research is done by the staff at the observatory with help from professors and post-doctoral students from many institutions. The observatory is different from other national radio observatories because of its extensive work with graduate students, who can come to the observatory for long-term observation, benefitting not only the students, but also the observatory as it allows for more comprehensive projects to take place〔
