... High-resolution Halpha observations reveal the existence of an unusual bar in the disk of NGC 1808 at a position angle of 155 degr, about 20 degr offset from the major axis. ... A remarkably similar bar has been found in the galaxy NGC 7479. The outer parts of the HII region chain in NGC 1808 coincide with maxima in the HI gas distribution and further out connect to the outer spiral arms. The streaming of gas along the bar is clearly seen in the HI velocity field. ...

... Increases in IR surface brightness appear to be affected by both increased radiation field strength and increased local gas density. Individual regions and the galaxy as a whole fall within the observed scatter of recent high-resolution studies of the radio-far-IR correlation in nearby spiral galaxies; this is likely the result of depleted radio and far-IR emission strengths in the ISM of this dwarf galaxy. ...

NGC 5128 is the closest example of a giant early type (elliptical or S0) galaxy. Although often dubbed as a peculiar elliptical galaxy since it has a dust lane with recent star formation and an active galactic nucleus, the majority of early type galaxies have similar structures as revealed by recent surveys. ...
