The Anisotropic Distribution of Satellite Galaxies
Contrary to several recent studies, we find strong evidence in the Sloan Digital Sky Survey for the “Holmberg Effect”, the tendency for the satellites of isolated late-type galaxies to align with the minor axis of the galactic disc. In the case of isolated earlytypes, we find that satellites tend to align with the major axis of the galaxy. Using mock catalogues generated from cosmological N -bo...
متن کاملPAIRED ANISOTROPIC DISTRIBUTION FOR IMAGE SELECTIVE SMOOTHING
In this paper, we present a novel approach for image selective smoothing by the evolution of two paired nonlinear partial differential equations. The distribution coefficient in de-noising equation controls the speed of distribution, and is determined by the edge-strength function. In the previous works, the edge-strength function depends on isotropic smoothing of the image...

متن کاملSome Implications of the Anisotropic Distribution of Satellite Galaxies
We examine a possible connection between the anisotropic distribution of satellite galaxies around giant spiral galaxies and the evolution of satellite systems. The observed polar anisotropy (Zaritsky et al. 1997) is either imprinted by initial conditions or develops from an initially symmetric distribution. We attempt to discriminate between these two possibilities by exploring the implication...
متن کاملAnisotropic Distribution of Sdss Satellite Galaxies: Planar (not Polar) Alignment
The distribution of satellite galaxies about isolated host galaxies in the second data release of the Sloan Digital Sky Survey (SDSS) is investigated. Host–satellite systems are selected using three different methods, yielding samples of ∼ 2100 satellites, ∼ 1300 satellites, and ∼ 650 satellites. All three samples of satellites show highly significant deviations from isotropy relative to the ma...
