For example, among the Milky Way's dE companions we see systems with dominant old populations, systems with minor intermediate-age (age ~ 2 to 10 Gyr) components, and systems where the intermediate-age component dominates the old stars. ... This variety of star formation histories is not restricted to the Galaxy's companions. ... To make progress in understanding the processes that govern dwarf galaxy evolution, we need to study systems beyond the Local Group. ...

... Radio emission at around 90 GHz from star-forming galaxies is expected to be strongly dominated by the free-free component due to ionising radiation from massive, short-lived, stars. We present high surface-brightness sensitivity observations at 90 GHz of the nearby star-forming galaxy Messier 66 with resolution of about 9 arcsec (corresponding to a physical scale of about 500 pc) and analyse these observations in combination with archival lower frequency radio and mid-infrared measurements. ...

... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...

Models of galaxy formation and evolution within the Ю?-CDM paradigm can be tested against their predictions on the number and properties of dwarf galaxies and in particular stellar systems highly dominated by dark matter. ... The authors argue that the third possibility is the most likely one and hence SECCO1 would be a new faint dwarf galaxy residing in the Virgo cluster of galaxies. ...
