Title: Young star-forming regions in NGC4449 as seen with SITELLE
Presenter: Anne-sophie Roy
Abstract:
SIGNALS is studying thousands of HII regions in various galactic environments across more than thirty nearby galaxies, using SITELLE with a spatial resolution ranging from 2 to 40 pc. While emission lines in the three SN filters allow for the detection and study of HII regions, the continuum maps from these filters highlight stellar clusters. To model and understand the physical processes linking HII regions and star-forming clusters, a detailed analysis of the physical properties (age, mass, metallicity, and extinction) of clusters is being conducted for the dwarf irregular galaxy NGC 4449. This project aims to assess SITELLE’s ability to determine the physical properties of star clusters by developing a stellar population synthesis method adapted to its data.
