United KingdomAstronomers have discovered a new barred spiral galaxy named M1149-BSG-z5 using the James Webb Space Telescope (JWST). The galaxy, located at a redshift of 5.1, is notable for hosting a stellar bar measuring approximately 14,700 light-years in length, making it the highest-redshift barred galaxy identified to date. It has an effective radius of about 8,500 light-years, with spiral arms extending up to 17,900 light-years. The galaxy's mass is estimated at 28 billion solar masses, and it exhibits a star-formation rate of 144 solar masses per year. Additionally, M1149-BSG-z5 hosts an active galactic nucleus (AGN) with a relatively low black-hole-to-stellar mass ratio, suggesting it may represent a transitional phase in galaxy evolution. The findings were published on the preprint server arXiv.
