Radio observations of IC 4662, NGC 5398, and NGC 1705 are used in combination with optical images to search for extremely young star clusters that are ... young optical clusters and radio clusters in IC 4662 are spatially exclusive—supporting either large amounts of extinction in the vicinity of the radio clusters or sequential star formation. No thermal sources are detected in NGC 1705 down to a 3 σ level of ∼ ...

... data of two nearby irregular dwarf galaxies: IC 4662 and NGC 5408. The HI line data were obtained with ... typically offset from the prominent HII regions. While NGC 5408 shows a fairly regular HI velocity field, which allows us to derive a rotation curve, IC 4662 reveals a rather twisted HI velocity field, possibly caused by a recent merger event. We detect outflows with velocities between 20 and 60 km/s in our Halpha spectra of both galaxies, sometimes with HI counterparts of similar velocity. We suggest the existence of expanding superbubbles, especially in NGC 5408. This is also supported by the detection ...
