NGC 628 in SIGNALS: Explaining the Abundance-ionization Correlation in H ii Regions

The variations of oxygen abundance and ionization parameter in H ii regions are usually thought to be the dominant factors that produced variations seen in observed emission-line spectra. However, if and how these two quantities are physically related is hotly debated in the literature. Using emissi...
