New DEVILS Survey Reveals How Galaxies Evolve Based on Their Cosmic Neighborhoods

The first data from the Deep Extragalactic Visible Legacy Survey (DEVILS) has been released to the public. This marks a significant step in understanding how a galaxy’s position in the universe affects its growth and shape. DEVILS is the first survey to examine the distant universe in such detail, reaching back up to five billion years. It focuses on how a galaxy’s surroundings—whether crowded or isolated—influence its evolution. Researchers can now access this data to study star counts, star formation rates, and the visual structure of galaxies.

The survey reveals that galaxies in dense regions grow more slowly and develop different structures compared to those in quieter areas. Competition for resources and interactions between galaxies can slow down early star formation. DEVILS also maps the small-scale environment of galaxies, comparing it to varied landscapes like mountains, hills, and valleys.

The team behind DEVILS plans to expand the project further with the upcoming WAVES survey. This will build on the current findings and deepen the understanding of galactic evolution. The public release of DEVILS data allows other researchers to explore these discoveries. It provides new tools to analyse how location shapes a galaxy’s size, structure, and development. The findings confirm that environment plays a crucial role in the life cycle of galaxies.
