The Dark Energy Spectroscopic Instrument (DESI) is a scientific research instrument for conducting spectrographic astronomical surveys of distant galaxies. Its main components are a focal plane containing 5,000 fiber-positioning robots, and a bank of spectrographs which are fed by the fibers.
The researchers used a year of observations by the Dark Energy Spectroscopic Instrument (DESI) at Kitt Peak National Observatory in Arizona, which can capture light from 5,000 galaxies simultaneously.
This story was first published on Nov. 19, 2024. It was updated on Nov. 20, 2024 to correct the location of the telescope used by the Dark Energy Spectroscopic Instrument. It is southwest of Tucson, Arizona, not in Tucson. It also corrects the description of the instrument's three-dimensional map of the universe.
A major project started in the 2010s is the Dark Energy Spectroscopic Instrument (DESI) for the 4-meter Mayall telescope, for conducting spectrographic astronomical surveys of distant galaxies probing the expansion history of the universe and the mysterious physics of dark energy. [12] [13]
She is Commissioning Scientist and calibration scientist on the Dark Energy Spectroscopic Instrument (DESI). [13] [14] She served as the interim director of UCO from the retirement of Claire Max in July 2021 until the appointment of Bruce McIntosh in September 2022. [15] [16] [17]
Called the Dark Energy Spectroscopic Instrument, it uses a telescope based in Tucson, Arizona to create a three-dimensional map of the universe’s 11-billion-year history to see how galaxies have clustered throughout time and across space. That gives scientists information about how the universe evolved, and where it might be heading.
Brenna Lynn Flaugher is an experimental cosmologist [1] who works as a distinguished scientist at Fermilab, where she heads the Astrophysics Department. [2] Flaugher led the development of the Dark Energy Camera at the Víctor M. Blanco Telescope in Chile, part of the Dark Energy Survey; [3] [4] she has also been involved in the development of the Dark Energy Spectroscopic Instrument at the ...
The Dark Energy Survey (DES) is an astronomical survey designed to constrain the properties of dark energy. It uses images taken in the near- ultraviolet , visible , and near- infrared to measure the expansion of the universe using Type Ia supernovae , baryon acoustic oscillations , the number of galaxy clusters , and weak gravitational lensing ...
