A Landmark Survey for Dark Energy Research Originally assembled to feed target selection for the Dark Energy Spectroscopic Instrument (DESI), the map now serves as a foundational reference for a broad range of astrophysical investigations, enabling...

DECam Imaging in Narrowbands (ODIN) survey alongside precise spectroscopic measurements from the Dark Energy Spectroscopic Instrument (DESI) and telescopes in Hawaii and Chile, the team successfully transitioned from two-dimensional sky maps to complex...

of shattered exoplanets embedded in polluted white dwarf stars. A new analysis of data from the Dark Energy Spectroscopic Instrument (DESI) provides some of the most compelling evidence to date that dying stars are accreting fragments of shattered rocky...

or if it evolves over time. These space-based observations will complement data from the ground-based Dark Energy Spectroscopic Instrument (DESI), which maps the distribution of galaxies to track the universe’s structure. Saul Perlmutter (right) and...

(CGM), the vast reservoir of gas that envelops every major galaxy. By analyzing stacked data from the Dark Energy Spectroscopic Instrument (DESI) and the LOFAR Two-meter Sky Survey, researchers have identified a striking pattern: cool ionized gas...

distant objects to spot rare quasar lens candidates A machine‑learning pipeline has sifted through the Dark Energy Spectroscopic Instrument (DESI) catalog and identified seven new quasars that may also serve as strong gravitational lenses. If follow‑up...

observations from China’s Five-hundred-meter Aperture Spherical radio Telescope (FAST) and the Dark Energy Spectroscopic Instrument (DESI), researchers have determined that galaxies have managed to retain their gas supplies even as their ability to...

Rare star destruction reveals a wandering supermassive black hole, offering a fresh method to hunt these elusive cosmic giants. Astronomers using NASA’s Swift Observatory together with a worldwide network of telescopes have recorded a brilliant...
