... GSAOI Home . ... Science . ... It is widely accepted that the evolution of the large scale structure of the Universe is driven by dark matter. Understanding this dark matter continues to be one of Astronomy's great unsolved problems. Measuring the bulk motions of galaxies allows us to map the overall mass distribution of the Universe in a way that is independent of the luminous matter in galaxies. ...

It follows from our IR observations of the star (1986-2010) that its J-band brightness level in August, 2008 reached an absolute minimum (~12 m ), and till the beginning of the summer of 2010, the star was almost inaccessible for observations at 1.25 microns. ... The figure shows J-filter brightness variations of FG Sge in 1986-2010. ...

One of the insteresting results of Chandra and XMM-Newton observatories is the discovery of sharp structures in the X-ray surface brightness of galaxy clusters. These structures (a.k.a. cold fronts) are likely associated with the contacted discontinuities formed when a hot gas flows over a colder gravitationally bound gas cloud. ...
