Linking Clustering Properties and the Evolution of Low Surface Brightness Galaxies

摘要

The reasons for the presence of two branches of galaxy evolution, one producing highsurface brightness disks and one creating low surface brightness disks, is still unknown. Possibleare the imprint of the properties of the dark matter halo, as well as evolutionary effects. In thispaper we present an analysis of the clustering properties of LSB and HSB galaxies using the SloanDigital Sky Survey. We show that LSB galaxies reside in regions of lower galaxy density thanHSB galaxies on all scales between 0.8 and 8 Mpc, from scales of galaxy pairs to filaments of theLarge Scale Structure. This implies a probable scenario of LSB galaxies preferentially formingas a result of local peaks in the large-scale valleys of the primordial density distribution.
