Description

We present a study of the excitation conditions and metallicity of ionized gas (Zgas) in eight nearby barred and unbarred spiral galaxies from the VIRUS-P Exploration of Nearby Galaxies (VENGA) survey, which provides high spatial sampling and resolution (median ∼387 pc), large coverage from the bulge to outer disc, broad wavelength range (3600–6800 Å), and medium spectral resolution (∼120 km s−1 at 5000 Å). Our results are: (1) We present high resolution gas excitation maps to differentiate...[Show more]
