Resolved HII Regions with SIGNALS
Nebular emission lines are some of our most powerful tools for studying galaxies. From a handful of bright lines, we routinely estimate properties of star-forming regions (and …
Optical Strong Line Ratios Cannot Distinguish Between Stellar Populations and Accreting Black Holes at High Ionization Parameters and Low Metallicities
High-redshift observations from JWST indicate that optical strong line ratios do not carry the same constraining power as they do at low redshifts. Critically, this prevents a …
