XV Serbian Conference on Spectral Line Shapes in Astrophysics
Published by: Astronomical Observatory Belgrade

We present a comprehensive study of the nearby dwarf irregular galaxy NGC 2366 -a local analog of Green Pea galaxies. We focus on the spectral analysis to investigate the local gas kinematics, excitation, and metallicity of star-forming regions both in the most bright region Mrk 71 and the regions beyond. Observations were conducted using the SCORPIO-2 multimode focal reducer on the 6-m BTA Russian telescope, employing both Fabry-Perot Interferometer (FPI) data and long-slit spectroscopy. The FPI data allowed us to map gas kinematics in the Hα emission line, revealing complex velocity structures across the galaxy and regions with significant non-thermal broadening, indicative of outflows and potential supernova remnants. Long-slit spectroscopy provided detailed information on the ionization state and chemical abundances of galactic HII regions. We derived electron temperatures and oxygen abundances using the direct Te method, revealing variations across the galaxy. In particular, we examined the prominent star-forming region Mrk 71 and its associated outflow, characterizing their complex spectral features and report the discovery of a new Wolf-Rayet star candidate.
