WebAuthor(s): Rashkov, Valery Advisor(s): Madau, Piero Abstract: The halo of the MilkyWay (MW) contains residual evidence of its hierarchical accretion history, such as stellar streams, dwarf satellite galaxies and possibly even intermediate-mass black holes the latter carried as they fell into the larger Galaxy. The discovery and study of these objects have … WebIn a hierarchical universe, galaxies form by a similarmerging and accretion process as clusters (Klypin et al. 1999). Over-merging on galactic scales is a necessary requirement, other-wise previous generations of the hierarchy would preclude the formation of disks. Observations suggest that overmerging has been nearly complete on galactic scales. WebSpectral line and continuum observations of the ionized and molecular gas in G20.08-0.14 N explore the dynamics of accretion over a range of spatial scales in this massive star … current a. p. football poll
