UMass Amherst Astronomers Dust-obscured Star Formation Normal Distant Galaxy
2017/3/30
Pushing the limits of the largest single-aperture millimeter telescope in the world, and coupling it with gravitational lensing, University of Massachusetts Amherst astronomer Alexandra Pope and colle...
Astronomers using the National Science Foundation's Very Large Array (VLA) found surprisingly energetic activity in what they otherwise considered a "boring" galaxy, and their discovery provides impor...
Unexpected Formation Modes of the First Hard Binary in Core Collapse
Stellar dynamics, Method: N-body simulation, globular clusters: genera
2011/10/12
The conventional wisdom for the formation of the first hard binary in core collapse is that three-body interactions of single stars form many soft binaries, most of which are quickly destroyed, but ev...

A new mechanism for the formation of cometary tails behind dense clouds or globules is discussed. Numerical hydrodynamical models show that when a dense shell of swept-up matter overruns a cloud, mate...
