Institute for Astronomy (Hawaii) in the context of "Scott S. Sheppard"

Richard Brent Tully (born March 9, 1943) is a Canadian-born American astronomer at the Institute for Astronomy in Honolulu, Hawaii.

Born in Toronto, Ontario, and raised in Vancouver, British Columbia, Tully's specialty is the astrophysics of galaxies. With J. Richard Fisher, he proposed the Tully–Fisher relation, which shows that the luminosity of a galaxy and the orbital velocities of its stars are correlated. This relation can be used to determine the distances of galaxies and, by inference, the size and age of the universe. His books The Nearby Galaxies Atlas & Catalog published in 1988 give the 3D locations for 2,400 galaxies within 130 million light years of Earth. A particularly remarkable discovery was that our Milky Way galaxy lies adjacent a vast underdense region that Tully called the Local Void. A more extended compilation of 30,000 galaxies within a cube of diameter 700 million light years centered on Earth can be visually navigated with the planetarium computer software Starry Night Pro, where the data is called the Tully Database.

David James Tholen (born 1955) is an American astronomer at the Institute for Astronomy of the University of Hawaiʻi. He holds a 1978 B.S. from the University of Kansas, a 1984 PhD from the University of Arizona, and specializes in planetary and Solar System astronomy. He is a discoverer of minor planets and known for the Tholen spectral classification scheme used on asteroids.

The Haleakalā Observatory, also known as the Haleakalā High Altitude Observatory Site, is Hawaii's first astronomical research observatory. It is located on the island of Maui and is owned by the Institute for Astronomy of the University of Hawaiʻi, which operates some of the facilities on the site and leases portions to other organizations. Tenants include the Air Force Research Laboratory (AFRL) and the Las Cumbres Observatory Global Telescope Network (LCOGTN). At over 3,050 meters (10,010 ft) in elevation, the summit of Haleakalā is above one third of the Earth's troposphere and has excellent astronomical seeing conditions.
