Title:
The gas and stellar content of the LSB galaxy MCG+00-03-004 as seen by MUSE

Abstract:
A low surface brightness galaxy (LSB) has a surface brightness magnitude lower than the night sky. The LSB galaxy MCG+00-03-004 has been recently observed with the MUSE spectrograph. The data revealed an irregular morphology and a plethora of HII regions heterogeneously distributed. The final goal of this project has been to gain insight into the properties of the galaxy's baryonic matter. At first, we characterised the overall stellar populations to subtract the stellar continuum. Then we determined the number and properties of its HII regions, including distribution, Hα luminosity, extinction, density, temperature and metallicity. Finally, we studied the internal kinematics of the galaxy, in particular, looking for regular motions of gas and comparing its rotational curve to other studies on LSB galaxies.
