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. ...

... The highly obscured cases in our sample are generally the bright, central regions of galaxies with high overall attenuation but are not otherwise remarkable. ... The small fraction of highly obscured regions seen in this sample of normal, star-forming galaxies suggests that on 500 pc scales the timescale for significant dispersal or breakup of nearby, optically thick dust clouds is short relative to the lifetime of a typical star-forming region. ...

Arecibo Galaxy Environment Survey (AGES) The M74 group is a gas-rich galaxy group located at roughly 10 Mpc and is similar in makeup to the Local Group. M74 dominates the surrounding region and is accompanied by several dwarf galaxies, some of which are star-forming. ... We have decided upon a drift mapping approach to scan the entire region. We have defined 5 constant declination scans 5 in length, separated by approximately one full ALFA footprint. ... START TIME (AST) . END TIME (AST) . ...

... We have mapped the 21-cm absorption in the nuclear region of the starburst galaxy NGC 1808 using the VLA AnB-hybrid array with a resolution of approx. 5.2" (= 275 pc). ... The velocity center of the absorption changes from about +120 km/s relative to the systemic velocity in the NW to -145 km/s in the SE, following the rotation pattern in the outer regions of the galaxy. ... The gravitational mass required to explain this fast rotation in the center of NGC 1808 is a few times 10^9 solar masses. ...
