Cool Dense Gas in Early-Type Galaxies
C. Henkel,T. Wiklind +1 more
TL;DR: In this article, a review summarizes the observational results related to the neutral gas phase and presents a systematic comparison with other interstellar and stellar data, including the discovery of very dense molecular gas in the nuclear regions of early-type galaxies, the possible existence of a dust component neither seen optically nor in CO, internal inconsistencies of cooling flow scenarios, the origin of the cool gas, the presence of massive stars, aspects of galaxy evolution, and possibilities for future research are discussed in the light of new data.
Book ChapterDOI
Resolved Stellar Populations as Tracers of Outskirts
TL;DR: Galaxy haloes contain fundamental clues about the galaxy formation and evolution process: hierarchical cosmological models predict haloes to be ubiquitous and to be (at least in part) the product of past merger and/or accretion events as mentioned in this paper.
Journal ArticleDOI
Photometric Studies of the Extreme SMC Wing
TL;DR: The Magellanic Stream is interpreted as an instance of tidal disruption as discussed by the authors, and the observed difference between the composition of the Stream and the stellar systems (at least 80 percent stars) is noted.

Constraints on the existence of dark matter haloes by the M81 group and the Hickson compact groups of galaxies
Wolfgang Oehm,Pavel Kroupa +1 more
TL;DR: In this paper, the results of the employment of the Markov Chain Monte Carlo method and the genetic algorithm show statistically substantial merger rates between galaxies, and long living constellations without merging galaxies comprise - apart from very few instances - initially unbound systems only.
