Description

Galactic superwinds – large outflows of gas created by a combination of supernova explosions and stellar winds – are closely connected to a galaxy’s earliest stages of development and evolution, including aspects like its size, shape, and even how many stars will eventually call it home.

Recently, published researchers were able to construct three-dimensional simulations that uniquely predict the observed morphology of superwinds.

According to Dustin Nguyen, lead author of the paper and a graduate student in physics at The Ohio State University, their work shows that the underlying geometric assumptions of where stars release energy is important to understanding galactic evolution. Their research found that starburst rings, instead of spheres, lead to outflows more akin to what is observed in nature.
