A Milky Way-like barred spiral galaxy at a redshift of 3
The majority of massive disk galaxies in the local Universe show a stellar barred structure in their central regions, including our Milky Way 1,2. Bars are supposed to develop in dynamically cold stellar disks at low redshift, as the strong gas turbulence typical of disk galaxies at high redshift suppresses or delays bar formation 3,4. Moreover
