Universe Today Podcast [Interview] Unveiling The Most Obscured Part of Our Galaxy
Jun 10, 2025
Dr. Cara Battersby, an associate professor at the University of Connecticut and head of the Milky Way Laboratory, reveals fascinating insights about the previously obscured center of our galaxy. She discusses how modern telescopes have unveiled the complex dynamics of star formation near the supermassive black hole, Sagittarius A*. Cara also highlights the challenges of creating a 3D map of the central molecular zone, the role of the ALMA telescope, and ongoing research that could reshape our understanding of cosmic phenomena.

Episode notes
Star Formation Triggered by Gas Collisions
- Gas flowing into the center likely collides at hotspots triggering star formation.
- Confirming these locations and effects requires understanding the 3D structure of the region.
Supernovae Shape Galactic Center
- Supernova remnants abound in the galactic center, creating large bubbles and enriching the metallicity.
- High supernova frequency results from many star generations in this dense region.
ALMA Maps Galactic Center in Detail
- ALMA is mapping the galactic center at high resolution in many spectral lines.
- This survey reveals locations of shocks and star formation to improve 3D models of the region.
