Unveiling the Missing Link: Stripped Dwarf Galaxies Shed Light on Ultra-Compact Dwarf Galaxy Formation

Astronomers using the Gemini North telescope have discovered over 100 dwarf galaxies transitioning into ultra-compact dwarf galaxies, confirming that many ultra-compact dwarf galaxies are the remnants of stripped dwarf galaxies. This fills in the missing link in understanding the formation of ultra-compact dwarf galaxies, which are more compact than other galaxies with similar mass but larger than star clusters. The findings provide valuable insights into the evolutionary process and the role of the local environment in the formation of these enigmatic objects.
