22 de may. de 2023 · This galaxy is both a likely descendent of the highest-redshift submillimetre galaxies and quasars, and a likely progenitor for the dense, ancient cores of the most massive local galaxies.

Currently, the objects with the highest known redshifts are galaxies and the objects producing gamma ray bursts. The most reliable redshifts are from spectroscopic data, and the highest-confirmed spectroscopic redshift of a galaxy is that of JADES-GS-z13-0 with a redshift of z = 13.2, corresponding
22 de feb. de 2023 · Galaxies with stellar masses as high as roughly 10 11 solar masses have been identified 1, 2, 3 out to redshifts z of roughly 6, around 1 billion years after the Big Bang.
21 de nov. de 2022 · We present a reduction and analysis of the James Webb Space Telescope (JWST) SMACS 0723 field using new post-launch calibrations to conduct a search for ultra-high-redshift galaxies (z > 9) present within the Epoch of Reionization.
28 de jul. de 2022 · The higher the redshift, the farther back in time we see a galaxy.) Just a week after the release of the first science images from JWST, astronomers were reporting the detection of galaxies at...
Hace 2 días · Age of massive galaxies at redshift 8. Recent James Webb Space Telescope (JWST) data analyses have shown that massive red galaxies existed at redshifts z > 6, a discovery that is difficult to understand in the context of standard cosmology ( Λ CDM). Here we analyze these observations more deeply by fitting a stellar population model to the ...
