Quadruple-peaked Line-of-sight Velocity Distributions in Shell Galaxies
We present an improved study of the expected shape of the line-of-sight
velocity distribution in shell galaxies. We found a simple analytical
expression connecting prominent and in principle observable characteristics of
the line profile and mass-distribution of the galaxy. The prediction was
compared with the results from a test-particle simulation of a radial merger.Comment: 2 pages, 1 figure, to appear in the Proceedings of JENAM 2010,
