TL;DR
The paper discusses how the next-generation Very Large Array (ngVLA) will enable comprehensive studies of HII regions across the galaxy, addressing longstanding questions and offering a new method for measuring star formation.
Contribution
It introduces the capabilities of the ngVLA to systematically observe HII regions and improve understanding of their physics and role in star formation.
Findings
ngVLA will provide a galaxy-wide sample of HII regions
It will help solve longstanding problems in HII region physics
It offers an extinction-free star formation tracer
Abstract
The ngVLA will create a Galaxy-wide, volume-limited sample of HII regions; solve some long standing problems in the physics of HII regions; and provide an extinction-free star formation tracer in nearby galaxies.
