Physical Properties of H ii Regions at Sub-kpc Scales Using Integral Field Spectroscopy on IC 342

n this study, we use Integral Field Spectroscopic (IFS) observations for one of the closest galaxies to us, the grand design spiral IC 342, to derive the physical properties of H II regions at sub-kpc scales. To our knowledge, the IFS data represent the most comprehensive observational effort in the optical range for this galaxy. The final IFS datacube consists of 349 individual pointings using IFS instrumentation from the SDSS-IV MaNGA survey. Using a prototype of the data analysis pipeline that will be devoted to the SDSS-V Local Volume Mapper (LVM) survey, we measured different observables from the optical emission line. In particular, using the flux map of the H𝛼 emission line, we derived the location and size of H II region candidates for IC 342 . Using the integrated flux for different emission lines within each region, we derived the radial distribution of different physical properties from the ionized gas (e.g., optical extinction, H𝛼 luminosity, oxygen abundance, etc.). Compared with larger samples of galaxies with IFS data, our results suggest that the physical properties of the ionized gas of IC 342 are similar to those of galaxies with similar stellar masses in the nearby universe.
