Axisymmetric models for galaxies by equipotential and equidensity methods

TL;DR

This paper presents equipotential and equidensity methods for constructing axisymmetric galaxy models, allowing for flexible and direct modeling of galaxy density and potential distributions.

Contribution

It introduces and compares two novel approaches—equipotential and equidensity methods—for building axisymmetric galaxy models.

Findings

Equipotential method derives densities from potential surfaces.

Equidensity method directly defines density surfaces.

Both methods facilitate flexible galaxy modeling.

Abstract

In this paper we outline equipotential and equidensity methods of constructing axisymmetric models for galaxies. The former method defines equipotentials, from which the corresponding densities of the galaxy models can be obtained using Poisson's equation; the latter defines the equidensity surfaces of the galaxy models directly.
