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 spherical aberration affecting the HST primary mirror (Burrows et al. 1992) can seriously alter the core brightness profile of elliptical galaxies. ... In this paper we test the performance of deconvolution in recovering the original surface brightness profile in the case of elliptical galaxies observed with the HST Planetary Camera (PC). ...

Outline of the BTF paper by Erwin de Blok (25-2-2002) ----------------------------------------------------- * Description of sample * Data and corrections * Descriptions of method to measure line widths * Description of method to measure inclinations * Corrections to linewidths and magnitudes (inclination, random motion, instrumental resolution, extinction) * Corrections to recession velocities (to Local Group frame, also POTENT etc for nearby galaxies) * Describe B-band ...

... 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. ...

... 1994: . Deep CCD images of the bright gamma-ray bursts GRB790418 and GRB790613 localization regions were obtained for the first time. In both cases, a faint blue star-like object (V = 24.5 m , BV m ) was detected within the region of localization of gamma-ray bursts. ... Based on sixty daily instantaneous spectra of the object SS433, obtained on the RATAN-600 in April-May 1994, we traced its variability in four very powerful flares at five frequencies. ...
