Orientations of very faint galaxies in the Coma cluster
C. Adami, R. Gavazzi, J. C. Cuillandre +5
We have then searched for preferential orientations of faint galaxies in the Coma cluster (down I_Vega~-11.5). By applying a deconvolution method to deep u* and I band images of th…
Numerical investigation of lenses with substructures using the perturbative method
Sébastien Peirani, Christophe Alard, Christophe Pichon +2
We present a statistical study of the effects induced by substructures on the deflection potential of dark matter halos in the strong lensing regime. This investigation is based on…
Late-time observations of SN2006gy: Still Going Strong
Nathan Smith, Ryan J. Foley, Joshua S. Bloom +9
Owing to its extremely high luminosity and long duration, SN2006gy radiated more energy in visual light than any other known SN. Two hypotheses to explain its high luminosity -- th…
The Sloan Lens ACS Survey. VI: Discovery and analysis of a double Einstein ring
Raphael Gavazzi, Tommaso Treu, Leon V. E. Koopmans +4
We report the discovery of two concentric Einstein rings around the gravitational lens SDSSJ0946+1006, as part of the Sloan Lens ACS Survey. The main lens is at redshift zl=0.222,…
