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. ...

... 2008 February 13 . Elliptical Galaxy NGC 1132 . Credit: NASA , ESA , M. West ( ESO, Chile ), and CXC / Penn. ... Explanation: NGC 1132 is one smooth galaxy -- but how did it form? As an elliptical galaxy , NGC 1132 has little dust and gas, and few stars have formed in it recently. Although many elliptical galaxies are in clusters of galaxies, NGC 1132 appears as a large, isolated galaxy toward the constellation of the River (Eridanus). ... About APOD | ...

... By means of deep optical images obtained at the Special Astrophysical Observatory 6-m telescope it was discovered that some Seyfert galaxies that were earlier considered to be non-interacting objects displayed signatures of elongated tidal envelopes belonging to satellite debris. ... Our results suggest that statistic studies based on popular imaging surveys (for example SDSS) can lead to an underestimation of the fraction of minor mergers among galaxies with active nuclei (AGN). ...

... The (1-0) observations were taken in 2004 August/September with the Compact Array at 18.6 GHz. ... This chemistry is well traced by the (1-0) transitions of the HCN and HNC molecules which emit at 88.6 and 90.7 GHz, respectively. ... These observations therefore suggest that the HCN/HNC ratio may be an indicator of massive star formation.

... More recently, I have been concerned with observing masers located in the circumstellar shells generated by red giant stars in their mass-loss phase, and in what we can therefore learn about the late stages of stellar evolution. 100 mJy are now undetectable after ~12 years, aka the DEATH of an OH/IR star or its cyclical evolution back to a Mira variable. ... I find that this momentum flux is sufficient to support the largest observed rates of AGB mass-loss. last updated: 14 January 2015 . ...
