On an empirical method to build near-equilibrium axisymmetric and triaxial galaxy models

Year: 2026

Type: preprint

Abstract: We present a numerical technique to implement $N$-body realizations of axisymmetric and triax- ial self-gravitating system starting from a spherical self-consistent models for which a phase-space distribution is known. The method builds up on the so-called adiabatic squeezing technique by K. Holley-Bockelmann et al. (2001) and ideally allows to control the effective ellipticities of the particle distribution. We discuss some preliminary tests and sketch a possible improvement of our method
