Abstract: We present high-resolution observations of Henize 2-10 in K s (2.2 μm), L ' (3.8 μm), and M ' (4.8 μm) bands. These allow us, for the first time, to track accurately the structures at the heart of the galaxy from the optical to the radio. All radio knots previously observed can now be associated with L '- and K s -emitting regions. This implies a revision of their physical nature. Instead of highly extinguished ultradense H II regions, we propose that two of the five radio knots are either supernova remnants or normal H II regions, while the remaining three are bona fide ultradense H II regions, although less obscured than previously thought.
