On 13 June 2023 the DESI Early Data Release (EDR) was announced. [26] The EDR contains spectra of nearly two million galaxies, quasars and stars. [22] One early result of the EDR was announced in February 2023 and described a mass migration of stars into the Andromeda Galaxy. [27] The EDR also revealed very distant quasars and very metal-poor ...
Desorption electrospray ionization (DESI) is an ambient ionization technique that can be coupled to mass spectrometry (MS) for chemical analysis of samples at atmospheric conditions. Coupled ionization sources-MS systems are popular in chemical analysis because the individual capabilities of various sources combined with different MS systems ...
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.

Due to uncertainties in the data pipeline, the third data release, based on 34 months of observations, has been split into two parts so that data that was ready first, was released first. The first part, EDR3 (Early Data Release 3), consisting of improved positions, parallaxes and proper motions, was released on 3 December 2020. [ 24 ]
Annual release data products will be made available once a year, by re-processing the entire science data set to date. These include: Calibrated images; Measurements of positions, fluxes, and shapes; Variability information; A compact description of light curves; A uniform reprocessing of the difference-imaging-based prompt data products
The agency did not disclose which data points were released early. The monthly CPI report is among the most followed economic data series published by the U.S. government.
DESY's function is to conduct fundamental research for solely civil and peaceful purposes. It specialises in particle accelerator development, construction and operation, particle physics, astroparticle physics and photon science research to explore the fundamental relationships between the structure, dynamics and function of matter.
