The young stars are characterized by a turbulent rotation pattern that still carries the imprint of the angular momentum distribution in the original cloud or star cluster.Reinhard Genzel MpeUC BerkeleyGenzel R. et al., The Nuclear Star Cluster of the Milky Way: Star Formation, Dynamics and ...
Binary star system found near the Milky Way's black hole Scientists have uncovered the existence of a binary star system close to the black hole near the center of the Milky Way galaxy, confirming a hypothesis made by happenstance nearly a century ago. ...
The last 10-20 years has seen a profound shift in views of how the Galaxy's halo formed. The idea of a monolithic early collapse of a single system (Eggen, Lynden-Bell and Sandage 1962) has been challenged by observations at high redshift and by cosmolog

"We're very excited that this object could be the tip of the iceberg — that it could be the first example of a new class of extremely faint stellar systems that have eluded detection until now," said Cerny. The team, led by another grad student, Simon Smith at the University of Victo...

High resolution infrared imaging and spectroscopy have given in the past five years very valuable new information on the central star cluster of the Milky Way. A review is given what these observations tell us about character and evolution of the cluster, and in particular about the stellar dynam...
Our model assumes that the Milky Way is formed from a closed box-like system in the inner regions, while the outer parts of the disc experience some accretion. Unlike the usual procedure, we do not fix the star formation prescription (e.g. Kennicutt law) in order to reproduce the ...
