Recent Star Formation in Very Luminous Infrared Galaxies
Among star forming galaxies, a spectral combination of a strong Hδ line in absorption and a moderate [Oii] emission has been suggested to be a useful method to identify dusty starburst galaxies at any redshift, on the basis of optical data alone. On one side it has been shown that such a spectral particularity is indeed suggestive of obscured starburst galaxies but, on the other, the degeneracy...
متن کاملRecent Star Formation in Nearby Early-type Galaxies
Motivated by recent progress in the study of early-type galaxies owing to technological advances, the launch of new space telescopes and large ground-based surveys, we attempt a short review of our current understanding of the recent star-formation activity in such intriguing galactic systems.
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 ...
متن کاملDiscussion: Star Formation Within Galaxies
This Discussion session focused on star formation within galactic scales. We attempt to identify the dominant physical processes and parameters that characterize star formation, and to identify key questions that illuminate these phenomena. The Discussion was delineated by the following cycle of three questions: (A) Is the top of the H ii LF physically distinct? (B) How does massive star feedba...
