Chemistry Unmasks a Spiral Galaxy’s Ancient History

Astronomers used chemical fingerprints from thousands of star-forming gas clouds in the nearby spiral galaxy NGC 1365 to reconstruct its 12-billion-year growth by matching observations to about 20,000 galaxy simulations. They found a centrally formed, oxygen-rich core with slower outer-disk growth, likely shaped by mergers with smaller galaxies and late gas inflows. This chemical-archaeology approach opens a new way to study how distant galaxies assembled over cosmic time.

Chemical fingerprints map the 12-billion-year saga of NGC 1365

Astronomers used high-resolution chemical maps of oxygen in the spiral galaxy NGC 1365, paired with simulations, to rewind its history over about 12 billion years—early central enrichment and slower outer-disk growth largely due to mergers with smaller galaxies—revealing a new way to study distant galaxies’ assembly.

Chemical fingerprints reveal a distant galaxy's 12-billion-year growth

Astronomers map oxygen emission patterns in the face-on spiral galaxy NGC 1365 and compare them with Illustris simulations to reconstruct its 12-billion-year history: rapid early enrichment in the core, growth into a large spiral through mergers with dwarf galaxies, and later outer-arm star formation, offering a concrete example of chemical archaeology and a window into how the Milky Way may have formed.
