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 SN 1998bv discovered on April 6, 1998 in the blue compact galaxy HS 1035+4758 is the second supernova observed in a low-mass galaxy with intense SF burst. ... According to its characteristic spectrum, SN 1998bv is a type II supernova with estimated peak absolute brightness M 16.3. The very slow fading of its brightness suggests that the SN was discovered at the Plateau phase, 20-30 days after the peak of the light curve. The most probable classification of SN 1998bv is regular SN II-P. 3. ...
