  • We report the discovery of spiral galaxies that are as optically luminous as elliptical brightest cluster galaxies, with r-band monochromatic luminosity L_r = 8–14L* (4.3–7.5 × 10^(44) erg s^(−1)). These super spiral galaxies are also giant and massive, with diameter D = 57–134 kpc and stellar mass M_(stars) = 0.3–3.4 × 10^(11)M⊙. We find 53 super spirals out of a complete sample of 1616 SDSS galaxies with redshift z 8L*. The closest example is found at z = 0.089. We use existing photometry to… CONTINUE READING
