DESI’s Galactic Survey Confirms Einstein’s Theory of Gravity at Cosmic Scales

This artist's illustration depicts the Large Magellanic Cloud (LMC) in the foreground as it passes through the gaseous halo of the much larger Milky Way galaxy. The encounter has stripped away much of the LMC's spherical gas halo, leaving a trailing gas stream resembling a comet's tail. However, a compact halo remains intact, and scientists predict this residual halo will not dissipate entirely. The research team studied the LMC's halo by analyzing the light from 28 quasars, exceptionally bright active galactic nuclei that act as "lighthouse beacons" across the universe. This light enables scientists to detect the halo gas indirectly, as the gas absorbs some of the quasars' light. The lines in the illustration represent the path of the Hubble Space Telescope's observations, from its orbit around Earth to the distant quasars, passing through the LMC's gas halo.

Hubble Reveals Impact of Galaxy’s Close Encounter with Milky Way

Velocity streamlines within the reconstructed volume, with colored envelopes associated with the prominent nearby basins of attraction. The map and streamlines have been cropped to the region covered by Cosmicflows-4 data. The streamlines within a given basin converge onto the region of high concentration of galaxies.

Unlocking the Secrets of the Universe: DESI’s Groundbreaking 3D Map Reveals Dark Energy Mysteries

This image, taken by the Very Long Baseline Array (VLBA), shows two supermassive black holes, which appear as the blobs with red strips. The black holes are in the center of an elliptical galaxy. Colors represent different spectral slopes in radio emission, with red showing the most dense regions surrounding the black holes. The black hole on the right has likely recently devoured a massive star, which caused it to shoot out two ultrafast jets. The ends of those jets appear as green blobs above and below the black hole. This object, called J0405+3803, is referred to as a Compact Symmetric Object (CSO), because its jets are relatively close-in (or compact), compared to other black holes with much larger jets.
