Abstract
Nearby blue compact dwarf galaxies (BCDs) are considered analogs to objects from the Epoch of Reionization revealed by JWST, having similarly low stellar masses, low metallicities, and high specific star formation rates. Thus, they represent ideal local laboratories for detailed multiwavelength studies of their properties and mechanisms that shape them. We report the first JWST MIRI/MRS observations of the BCD SBS 0335-052 E, analyzing MIR emission lines tracing different levels of ionization (e.g., [Ne ii ], [S iv ], [Ne iii ], [O iv ], [Ne v ]) of the ionized gas. SBS 0335-052 E MIR emission is characterized by a bright point source, located in one of the youngest and most embedded stellar clusters ( t ∼ 3 Myr, A _V ∼ 15), and underlying extended high-ionization emission (i.e., [O iv ] and [Ne v ]) from the surroundings of the older and less dusty stellar clusters ( t 54 eV) when modeling these low-metallicity environments, and thus other sources of ionization cannot be fully ruled out.
