Young stellar populations in the Antennae galaxies
Abstract
We use the spatially resolved MUSE guaranteed time observations of the Antennae galaxies to study the properties of HII regions with high SFRs. The high signal-to-noise spectroscopic observations with extended wavelength coverage show numerous stellar and nebular features commonly seen in spectra of starbursts, such as Wolf-Rayet features, Forbidden, Balmer and higher order Paschen lines. By self constantly modelling many of these features, we constrain the characteristic properties (e.g. stellar and gas metallicities, gas temperature etc.) of young stellar populations in these regions, which appear to be dominated by an approximately 4 Myr old stellar population. I will present intrinsic Hα SFRs and characteristic properties of these high SFR HII regions.
