Magnetic White Dwarf Stars in the Sloan Digital Sky Survey
S. O. Kepler, Ingrid Pelisoli, Stefan Jordan +10
To obtain a better statistics on the occurrence of magnetism among white dwarfs, we searched the spectra of the hydrogen atmosphere white dwarf stars (DAs) in the Data Release 7 of…
A sample of Seyfert-2 galaxies with ultra-luminous galaxy-wide NLRs -- Quasar light echos?
Mischa Schirmer, Ruben Diaz, Karianne Holhjem +2
We report the discovery of Seyfert-2 galaxies in SDSS-DR8 with galaxy-wide, ultra-luminous narrow-line regions (NLRs) at redshifts z=0.2-0.6. With a space density of 4.4 per cubic…

T. Erben, H. Hildebrandt, L. Miller +29
We present data products from the Canada-France-Hawaii Telescope Lensing Survey (CFHTLenS). CFHTLenS is based on the Wide component of the Canada-France-Hawaii Telescope Legacy Sur…
Radial Metallicity Distribution Breaks at Corotation Radius in Spiral Galaxies
Sergio Scarano, Jacques R. D. Lépine
We analyzed the relation between the corotation radii and the galactic radii at which breaks or changes of slope of the metallicity gradients occur in spiral galaxies. With this pu…
