DESCRIPTION:In extragalactic astrophysics\, the mechanisms governing morph
 ological evolution and structural diversity among galaxies represent funda
 mental enigmas. In this talk\, I will present about JADES-GS+53.18343-27.7
 9097\, a galaxy of mature morphology\, which emerged during one of the ear
 liest stages of the universe\, within its first 700 million years.\nWith a
  stellar mass exceeding 10^8.6 solar masses\, this star-forming galaxy exh
 ibits a tripartite structure\, comprising a compact core with a half-light
  radius of 144 parsecs\, a vigorous star-forming disc spanning 468 parsecs
 \, and a distinct star-forming clump—each characterised by unique star-f
 ormation histories. Remarkably\, the central stellar mass density of this 
 high-z galaxy approaches that of the most massive elliptical galaxies obse
 rved today\, despite its global mass being a mere one-thousandth of their 
 scale.\nFurthermore\, an intriguing revelation emerges from the radial pro
 file of the specific star-formation rate—a pronounced increase towards t
 he outskirts. This compelling evidence suggests the detection of inside-ou
 t growth within a high-z galaxy during the Epoch of Reionization\, compris
 ing of a proto-bulge and a star-forming disc.
