We have performed a study of the rate of recent star formation for a sample of nearby compact groups of galaxies which have been taken from the compilation of...

We present initial results from a survey of nearby AGN using the near infrared adaptive optics integral field spectrograph SINFONI. These data enable us to...

We present CO J = 1-> observations of the S0 galaxy NGC 404 obtained using the Nobeyama Millimeter Array. The spatial and velocity resolutions are 4' ' and 5 km...

At the edge of galaxies, in the lowest surface brightness regimes, lies the boundary where gas can collapse to form new stars. These regions remain largely...

We have observed 12 interacting galaxies using the Fabry-Perot interferometer GHαFaS (Galaxy Hα Fabry-Perot system) on the 4.2m William Herschel Telescope (La...

We summarize recent theoretical results dealing with the formation of massive stellar systems. The key premise is the high stellar density which leads to a very...

To determine the star formation histories of dwarf galaxies we use fossil methods. Compared to the color-magnitude diagrams analyzes, which are well tested and...

Given their low surface brightness, it is hard to determine high-quality spectra of dwarf galaxies outside the Local Group, where it is not possible to study...
