Dark Energy Spectroscopic Instrument is a Spectrograph designed to study the expansion of the universe and the properties of Dark energy, a mysterious component that drives this expansion, as described by Albert Einstein's theory of General relativity and observed by Supernova Cosmology Project and High-Z Supernova Search Team. The instrument is a collaboration between Lawrence Berkeley National Laboratory, University of California, Berkeley, University of Michigan, and other institutions, including Harvard University, California Institute of Technology, and Massachusetts Institute of Technology. The project involves scientists from around the world, including Nobel laureate Saul Perlmutter, Brian Schmidt, and Adam Riess, who have made significant contributions to our understanding of the Universe.

Introduction

The Dark Energy Spectroscopic Instrument is designed to measure the redshifts of millions of galaxies and quasars using optical spectroscopy, a technique developed by scientists such as Isaac Newton and Gustav Kirchhoff. This will allow scientists to create a detailed map of the universe, including the distribution of galaxy clusters and superclusters, which are held together by Gravity, as described by Galileo Galilei and Johannes Kepler. The instrument will be mounted on the Mayall Telescope at Kitt Peak National Observatory in Arizona, which is operated by the National Optical Astronomy Observatory and has been used for numerous astronomical surveys, including the Sloan Digital Sky Survey and the Dark Energy Survey. The Dark Energy Spectroscopic Instrument will also build on the legacy of other surveys, such as the 2dF Galaxy Redshift Survey and the WiggleZ Dark Energy Survey, which were conducted using telescopes such as the Anglo-Australian Telescope and the Magellan Telescopes.

Design and Construction

The Dark Energy Spectroscopic Instrument is designed to be a highly efficient and versatile instrument, capable of observing thousands of objects simultaneously, using a technique called Multi-object spectroscopy, which was developed by scientists such as Vesto Slipher and Milton Humason. The instrument consists of a Spectrograph with a large Focal plane and a Fiber optic system that can position thousands of fibers on the sky, allowing scientists to collect data on a large number of objects, including galaxies and quasars, which are studied by astronomers such as Maarten Schmidt and Richard Ellis. The instrument is being built by a team of engineers and scientists from Lawrence Berkeley National Laboratory, University of California, Berkeley, and other institutions, including Jet Propulsion Laboratory and NASA Goddard Space Flight Center, which have experience in building complex astronomical instruments, such as the Kepler space telescope and the Hubble Space Telescope.

Science Objectives

The primary science objective of the Dark Energy Spectroscopic Instrument is to measure the properties of Dark energy, which is thought to be responsible for the accelerating expansion of the universe, as observed by Supernova Cosmology Project and High-Z Supernova Search Team. The instrument will achieve this by measuring the redshifts of millions of galaxies and quasars, which will allow scientists to create a detailed map of the universe and study the distribution of matter and energy on large scales, using techniques developed by scientists such as Stephen Hawking and Roger Penrose. The instrument will also be used to study the properties of galaxy clusters and superclusters, which are held together by Gravity, as described by Galileo Galilei and Johannes Kepler. The Dark Energy Spectroscopic Instrument will build on the legacy of other surveys, such as the Sloan Digital Sky Survey and the Dark Energy Survey, which were conducted using telescopes such as the Sloan Telescope and the Blanco Telescope.

Instrumentation and Operations

The Dark Energy Spectroscopic Instrument will use a Spectrograph with a large Focal plane and a Fiber optic system to collect data on thousands of objects simultaneously, using a technique called Multi-object spectroscopy, which was developed by scientists such as Vesto Slipher and Milton Humason. The instrument will be operated by a team of astronomers and engineers from Lawrence Berkeley National Laboratory, University of California, Berkeley, and other institutions, including National Optical Astronomy Observatory and Kitt Peak National Observatory, which have experience in operating complex astronomical instruments, such as the Mayall Telescope and the WIYN Telescope. The instrument will be controlled using a sophisticated software system, developed by scientists such as Donald Knuth and Tim Berners-Lee, which will allow for efficient and automated data collection, using techniques developed by Google and Amazon Web Services.

Survey Strategy and Targets

The Dark Energy Spectroscopic Instrument will conduct a large-scale survey of the universe, targeting millions of galaxies and quasars over a wide range of redshifts, using a technique called Redshift survey, which was developed by scientists such as Hubble Space Telescope and Sloan Digital Sky Survey. The survey will be designed to optimize the measurement of Dark energy properties, using techniques developed by scientists such as Nobel laureate Saul Perlmutter and Brian Schmidt. The instrument will also target other objects of interest, such as galaxy clusters and superclusters, which are held together by Gravity, as described by Galileo Galilei and Johannes Kepler. The survey will be conducted in collaboration with other astronomical surveys, such as the Dark Energy Survey and the Large Synoptic Survey Telescope survey, which are conducted using telescopes such as the Blanco Telescope and the Simonyi Survey Telescope.

Data Analysis and Results

The data collected by the Dark Energy Spectroscopic Instrument will be analyzed using sophisticated software and algorithms, developed by scientists such as Donald Knuth and Tim Berners-Lee, which will allow for the extraction of precise measurements of redshifts and other properties of the observed objects, using techniques developed by Google and Amazon Web Services. The results will be used to create detailed maps of the universe, including the distribution of matter and energy on large scales, using techniques developed by scientists such as Stephen Hawking and Roger Penrose. The data will also be used to study the properties of Dark energy and the accelerating expansion of the universe, as observed by Supernova Cosmology Project and High-Z Supernova Search Team. The results will be published in a series of papers, which will be made available to the scientific community through online archives, such as arXiv and ADS, and will be presented at conferences, such as the American Astronomical Society meeting and the International Astronomical Union general assembly.
