Cooling Flow Star Formation and the Apparent Stellar Ages of Elliptical Galaxies.
Simple theoretical arguments indicate that cooled interstellar gas in bright elliptical galaxies forms into a young stellar population having a bottom-heavy but optically luminous initial mass function extending to approximately 2 M middle dot in circle. When the colors and spectral features of this young population are combined with those of the underlying old stellar population, the apparent ...
متن کاملSpatially resolved star formation histories of nearby galaxies: evidence for episodic star formation in discs
Using long-slit spectroscopy from Moran et al. (2012) we constrain the radial dependence of the recent star formation histories of nearby galaxies with stellar masses greater than 1010M⊙. By fitting stellar population models to the combination of SSFR, D4000 and HγA, we show that the star formation histories of many disk galaxies cannot be accurately represented if their star formation rates de...
متن کاملGas Flow and Star Formation in the ‘ Antennae ’ Galaxies
The prominent interacting galaxy pair NGC 4038/9 contains many active star-forming regions and is continuously forming new star clusters. We present a self-consistent n-body model for this system which includes an SPH gas component. The model qualitatively explains the apparent concentration of gas in the so-called overlap region between the two nuclei as a bridge of gas connecting the two gala...
متن کاملStar formation in galaxies and star clusters
This thesis is devoted to star formation from galaxy-scales (≈ 10 000 pc) to sub-star cluster-scales (≈ 0.1 pc). I develop and test a new method to derive star formation histories of Galaxies from their star cluster content, in particular the most massive star clusters. This is followed by an application of this method to the Large Magellanic Cloud, where the results of this new method are conf...
متن کاملStar Formation in Ring Galaxies
Ring galaxies are specific types of interacting galaxies in which a smaller galaxy has passed through the center of the disk of another larger galaxy. The intrusion of the smaller galaxy causes the structure of the larger galaxy to compress as the smaller galaxy falls through, and to recoil back after the smaller galaxy passes through, hence the ring-like shape. In our research, we studied the ...
