Star Formation in Extreme Environments
Galaxies which exhibit extreme star formation rates are called starburst galaxies. In such environments, the reservoir of molecular gas that feeds star formation is depleted on a short time-scale, typically 𝜏mol,dep ≈ 0.1 Gyr. High-redshift galaxies are frequently found to be in this state that strongly impacts the galaxy’s evolution. Although much less frequent, some nearby galaxies also harbor starburst regions, such as the central region of NGC 253. The unparalleled capabilities of the Atacama Large Millimeter/Submillimeter Array (ALMA) allow to study these galaxies in great detail on scales that could so far only be achieved in the Galactic Center.
