Searching for Stellar-Feedback-Driven Outflow Signatures: A Deep Dive into NGC 3741
Lexi N. Gault, Liese van Zee, Elizabeth A. K. Adams +5
Stellar feedback drives winds and outflows critical to the baryon cycles of low-mass galaxies whose shallow gravitational potential wells make them particularly susceptible to mass…
