Maarten Schmidt was a twentieth-century Dutch astronomer whose work significantly advanced our understanding of distant objects in space. He is best known for his 1963 identification of 3C 273 as a quasar. Through meticulous measurements of its redshift, Schmidt demonstrated the object's immense dis...
Martin Elvis is an astronomer specializing in modern astrophysics. He’s particularly recognized for his pioneering work analyzing X-ray emissions from quasars and active galactic nuclei. His research significantly advanced our understanding of these extremely luminous objects at the centers of galax...
Michael Strauss is an American astronomer at Princeton University who played a key role in the Sloan Digital Sky Survey, significantly advancing the mapping of the universe.
John Gatenby Bolton was a British-Australian astronomer who played a crucial role in the development of radio astronomy. He is best known for identifying the first discrete radio sources, such as Centaurus A and Virgo A, proving they originated from distant galaxies rather than stars within the Milk...
Belinda Wilkes is a British astrophysicist and a senior researcher at the Smithsonian Astrophysical Observatory in Cambridge, Massachusetts. From 2014 to 2020, she served as the director of the Chandra X-ray Center, managing the science and flight operations of NASA's Chandra X-ray Observatory. Her...
Xiaohui Fan is a Chinese-American astronomer and a professor at the University of Arizona's Steward Observatory. He is recognized for his observational work on high-redshift quasars, using large sky surveys like the Sloan Digital Sky Survey to identify some of the most distant known quasars. His res...
Donald G. York is an American astronomer associated with the University of Chicago. His research has covered quasars, the interstellar medium, and large astronomical surveys. York served as the founding director of the Sloan Digital Sky Survey, which combined wide-field imaging with spectroscopy to...
Donald P. Schneider is an American astronomer whose research has included quasars, active galactic nuclei, and large astronomical surveys. He was a professor at Pennsylvania State University and contributed extensively to the Sloan Digital Sky Survey, including its quasar catalogs. Schneider was the...
Jesse L. Greenstein was an American astronomer whose research centered on stellar spectroscopy and the physical properties of stars. Working at the California Institute of Technology, he made important studies of white dwarfs, stellar chemical composition, and unusual stellar spectra, and he partici...
Chris Impey is a British-born astronomer at the University of Arizona, known for observational cosmology and large-scale astronomy education since 1986.
French astrophysicist known for leading quasar survey analyses with SDSS and DESI to constrain cosmological parameters including the neutrino mass and dark energy equation of state.
