Ejin Formation
"相关结果 90条The stellar populations in the bulges of S0s, together with the galaxies' dynamics, masses and globular clusters, contain very interesting clues about their formation. I present here recent evidence suggesting that S0s are the descendants of fading spirals whose star formation ceased.
arxiv.orgWe review progress over the past decade in observations of large-scale star formation, with a focus on the interface between extragalactic and Galactic studies. Methods of measuring gas contents and star-formation rates are discussed, and updated prescriptions for calculating star-formation rates are provided. We review relations between star formation and gas on scales ranging from entire galaxies to individual molecular clouds.
arxiv.orgWe present evidence for star formation in distant radio galaxies based on deep FORS1/VLT spectropolarimetry and SCUBA/JCMT 850 micron photometry.
arxiv.orgThe conditions that lead to self-regulated star formation, star bursts and the formation of massive stellar clusters are discussed. Massive stars have a strong impact on their environment, especially on the evolution of dwarf galaxies which are the building blocks of giant galaxies. Energy input by massive young clusters might help to solve some of the most important puzzles of galaxy formation: the cosmological substructure problem and the angular momentum problem.
