In this gallery are many images of Low Surface Brightness Galaxies which have recently been discovered and analyzed. ... The central surface brightness of this galaxy is 24.28 . Malin 2 This galaxy is another huge disk galaxy with a scale length of 15 kpc and a redshift of 15000 km/a. The high surface brightness knot in one of its spiral arms actually has the same color, luminosity and H-alpha equivalent width as the entire Large Magellanic Cloud . ... Truly it is a Low Surface Brightness Galaxy. ...

The SAMI instrument on the AAT is currently taking integral field spectroscopy of ~3000 nearby galaxies as part of the SAMI Galaxy Survey. This is the largest sample ever across a broad range in both stellar mass and environment (from field galaxies to groups to clusters). Based on ionised gas and stellar kinematics in the SAMI galaxies, I will discuss the relationship between dynamical misalignments and the influence of environment, morphology and timescales on the origin of gas in galaxies. ...

... These Frontier Fields will combine the power of HST with the natural gravitational telescopes of high-magnification clusters of galaxies. ... We are soliciting gravitational lensing maps for the last four Hubble Frontier Fields clusters (MACSJ0717.5+3745, MACSJ1149.5+2223, AbellS1063, and Abell 370) based upon the exceptionally deep HST FF imaging and other new ancillary data. ...

... February 22, 1999 . NGC 1316: After Galaxies Collide . ... WFPC2 , HST , NASA . ... A preliminary inspection indicates that NGC 1316 is an enormous elliptical galaxy that started devouring a smaller spiral galaxy neighbor about 100 million years ago. ... Most elliptical galaxies have more and brighter globular clusters than evident in NGC 1316 . ... One hypothesis therefore holds that these globulars survive from an even earlier galaxy that was subsumed into NGC 1316. ... About APOD > . ...

We refined the fundamental parameters of the components, the orbital periods, and the conditions of photospheric heating of the secondary component by the ultraviolet radiation of the hot component. ... The observations of the star clusters associated with ultra-luminous x-ray sources (ULXs) in four galaxies on the 6-meter and VLT telescopes have shown that all the ULXs are located within 200pc of very young star clusters (younger than 5 million years). ...

These clusters are probably young versions of globular clusters, but they are commonly called super star clusters. Seven dwarf galaxies within 16 million light-years have formed super star clusters, with one of these galaxies, NGC 1569, possessing two young clusters. ... Super star clusters have a lot to tell us about star formation. ...
