... Science Users Information > Science Activities > PhD Thesis Topics offered by ESO Faculty Members > Thesis Topic: Planetary Nebulae and HII regions in the Elliptical Galaxy NGC 5128 . ... 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. ...

... 640W A survey of ultracompact (UC) Hii regions has been carried out by searching for 6.669-GHz methanol maser emission from a sample of 535 IRAS-selected candidates. A total of 201 candidates exhibit methanol emission. These sources have been used, in conjunction with previously identified UC Hii regions, to provide a base for further studies of such regions. ... Methanol maser and/or radio continuum emission is found in 364 cases towards IRAS-selected regions. ...

... Massive stars, having 10-150 masses of the Sun, with metallicities Z tens to hundreds times less than that of the Sun (Zo), are the main regulators of the galaxy formation and evolution processes in the early Universe. ... In this galaxy, using the 6 m BTA telescope, a new massive blue variable star with high luminosity (>=10 5 Sun's luminocities in visible light) was found. As far as its properties are concerned, this star falls into an LBV (Luminous Blue Variable) class of stars. ...
