  • Mass modelling of early-type systems is a thorny issue; even for the few close by galaxies for which kinematic data are available, the implementation of this data can get embroiled in problems that are hard to overcome, unless more complete data sets are available. The mass-anisotropy degeneracy is a typical example of this. In this paper, we present a new mass modelling formalism for ellipticals that invokes no other observations other than the central velocity dispersion (σ 0 ) and photometry… CONTINUE READING
