Much like how wind plays a key role in life on Earth by sweeping seeds, pollen and more from one place to another, galactic winds – high-powered streams of charged particles and gases – can change the chemical make-up of the host galaxies they form in, simply by blowing in a specific direction.
Using observations made by NASA’s Chandra X-ray Observatory, a new study details how these energetic winds, once released from the center of a galaxy, directly influence the temperature and metal distribution of the rest of the region.
“Galactic winds are a large part of galaxy evolution in general,” said Sebastian Lopez, lead author of the study and a graduate student in astronomy at The Ohio State University. “As they blow from one end of a galaxy to another, they alter the distribution of metals across the disk and enrich the surrounding intergalactic space.”
