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 ...
Schematic diagram of the DESI ion source. 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 ...
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.

DESI and DART are considered as pioneer techniques in the field of ambient ionization, [4] since they operate in the open laboratory environment and do not require sample pretreatment. [5] [6] In contrast to the liquid spray used by DESI, the ionizing gas from the DART ion source contains a dry stream containing excited state species.
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.
SEG-Y Files are stored in a hierarchical byte-stream format that combines both textual and binary data segments. The following chart shows the byte stream structure of revision 1 (2002), [5] with revision 2 (2017) only adding an optional data trailer for 1 or more 3200-byte records at the end: [6] [7]
Michael Glitz overdosed 10 days after leaving jail. Amanda Sue Watson died of an overdose a week after being transferred from jail to an abstinence-based halfway house. Henry Lee fatally overdosed one day after being released from the Kenton County jail. Desi Sandlin fatally overdosed the day she was released from jail.
During the early months of the COVID-19 pandemic, the need for published research on the disease spurred a wave of research articles being released as preprints, [12] bypassing the peer-review and publication process, which was proving too slow in the context of an active and novel pandemic. The release of COVID-related preprint articles, along ...
