) Large radio interferometers have been used to map the active jets emitted from active nuclei.

* LEDA, the Large Aperture Experiment to Detect the Dark Ages is a radio interferometer.

Large water-cooled triodes may be used as the final amplifier in radio transmitters, with ratings of thousands of watts.

" Large radio stations such as Westinghouse advocated that only 25 larger radio stations in large metropolitan areas be allowed to broadcast while smaller stations would be given limited power.

The Very Large Array, an interferometer | interferometric array formed from many smaller telescopes, like many larger radio telescopes.

A search for gravitational lenses in the northern hemisphere ( Cosmic Lens All Sky Survey, CLASS ), done in radio frequencies using the Very Large Array ( VLA ) in New Mexico, led to the discovery of 22 new lensing systems, a major milestone.

Large private telelocation or AVL systems send data from GPS receivers in vehicles to a dispatch center over their private, user-owned radio backbone.

* Atacama Large Millimeter Array, an array of radio telescopes in Chile

The use of the VLBA can be scheduled dynamically, and its sensitivity can be improved by a factor of five by including other radio telescopes such as the Very Large Array ( VLA ) in New Mexico and the Green Bank Telescope in West Virginia with the VLBA.

( 1988 ), who observed the radio source MG1131 + 0456 using the Very Large Array.

Ground-based radio astronomy is limited to high altitude sites such as Kitt Peak and Atacama Large Millimeter Array ( ALMA ) due to atmospheric absorption issues.

A radio enthusiast from an early age ( with an amateur radio station K2KOQ in a corner of the basement ), he became a DJ (" Large Sarge ") on WHVW in nearby Hyde Park, after helping build the station.

She has also starred in Stealing Heaven ( 1988 ), Inspector Morse ( 1989 ), Les Misérables ( 1998 ), David Copperfield ( 1999 ) and Kevin & Perry Go Large ( 2000 ) and numerous radio plays.

It was discovered by linking a " cold spot " in the cosmic microwave background to an absence of radio galaxies in data of the United States National Radio Astronomy Observatory's Very Large Array Sky Survey.

Scientific work conducted on the 14-meter radio telescope will be continued on the modern 50-meter Large Millimeter Telescope in Mexico.

However, even by using the significantly more sensitive Very Large Array, such a signal could not be detected, and the probability that a signal below the Very Large Array level could be detected by the Big Ear radio telescope due to interstellar scintillation is low.

* Very Large Array, a radio telescope array in the U. S.

Some terrestrial telescopes ( such as the Very Large Telescope ) can reduce atmospheric effects with adaptive optics.

For example, the Very Large Array ( VLA ) near Socorro, New Mexico has 27 telescopes with 351 independent baselines at once, which achieves a resolution of 0. 2 arc seconds at 3 cm wavelengths.

In September 2010 researchers from Australia said they had identified a dipole-like structure in the fine-structure constant across the observable universe, using data on quasars obtained by the Very Large Telescope, combined with the previous data obtained by Webb at the Keck telescopes.

When used together with adaptive optics, infrared interferometers, such as two 10 meter telescopes at Keck Observatory or the four 8. 2 meter telescopes that make up the Very Large Telescope Interferometer, can achieve high angular resolution.

Paranal Observatory, home of the Very Large Telescope, a cluster of four large ( 8. 2 meter diameter ) telescopes.

For example the Very Large Array has 27 telescopes giving 351 independent baselines at once.

* Large telescopes and telescope arrays.

* Very Large Telescope, a system of four large ( 8. 2 meter diameter ) optical telescopes organized in an array formation, located in northern Chile

These include the New Technology Telescope ( NTT ) that pioneered active optics technology, and the Very Large Telescope ( VLT ), consisting of four 8-metre-class telescopes and four 1. 8-metre auxiliary telescopes.

* The four 8. 2 m telescopes comprising the Very Large Telescope in Chile

The working group decided to concentrate on the northern CVZ, so that northern-hemisphere telescopes such as the Keck telescopes, the Kitt Peak National Observatory telescopes and the Very Large Array ( VLA ) could conduct follow-up observations.

Survey telescopes such as Large Synoptic Survey Telescope therefore try to maximize the product of mirror area and field of view ( or etendue ) rather than raw light gathering ability alone.

There are several large modern telescopes that use a Gregorian configuration such as the Vatican Advanced Technology Telescope, the Magellan telescopes, the Large Binocular Telescope, and the Giant Magellan Telescope.

* The first of four 8. 4 m reflecting telescopes opens in the Very Large Telescope program of the European Southern Observatory at Cerro Paranal in Chile.

Large telescopes are housed in domes, both to protect them from the weather and to stabilize the environmental conditions.

As of 2006, there are design projects underway for gigantic alt-az telescopes: the Thirty Metre Telescope, and the 100 m diameter Overwhelmingly Large Telescope

Large telescopes, with their small fields of view, cannot quickly scan a large enough piece of the sky to effectively observe transients seen by ALEXIS, but amateur equipment is well suited to the task.

Large gains are possible since any particular test vector usually only needs to set and / or examine a small fraction of the scan chain bits.

Large intensity gradients are more likely to correspond to edges than small intensity gradients.

For comparison, the circulating beams in the Large Hadron Collider, with ~ 11, 000 times higher energy and enormously higher intensity than the Bevatron, are confined to a space on the order of 1 mm in cross-section, and focused down to 16 micrometres at the intersection collision regions, while the field of the bending magnets is only about five times higher.
