Spectroscopic confirmation of two luminous galaxies at a redshift of 14
Stefano Carniani · JADES Collaboration
Summary
Using JWST/NIRSpec observations from the JWST Advanced Deep Extragalactic Survey (JADES), the authors obtained spectroscopic confirmation of two unusually luminous galaxies, JADES-GS-z14-0 and JADES-GS-z14-1, at redshifts of about 14. These are among the most distant galaxies ever spectroscopically confirmed, existing roughly 290–300 million years after the Big Bang. Their brightness challenges pre-JWST models of how rapidly luminous galaxies could form in the early universe.
Key findings
- Two galaxies were spectroscopically confirmed at z = 14.32 and z = 13.90.
- JADES-GS-z14-0 is surprisingly luminous and spatially extended (~260 parsecs), implying substantial stellar mass only ~290 million years after the Big Bang.
- The detections show luminous galaxies were already in place earlier and more common than many pre-JWST models predicted.
