Basis sets and Coulomb resolutions in rotational coordinates
Edward Lilley
Using generalised Laplacian symmetry operators, we construct basis sets or Coulomb resolutions in several separable coordinate systems, including two R-separable systems. This expa…
Schwarzschild Modeling of Barred S0 Galaxy NGC 4371
Behzad Tahmasebzadeh, Ling Zhu, Juntai Shen +15
We apply the barred Schwarzschild method developed by Tahmasebzadeh et al. (2022) to a barred S0 galaxy, NGC 4371, observed by IFU instruments from the TIMER and ATLAS3D projects.…
Dynamical modelling of ATLAS galaxies
Sabine Thater, Prashin Jethwa, Edward J. Lilley +3
Triaxial dynamical models of massive galaxies observed in the ATLAS3D project can provide new insights into the complex evolutionary processes that shape galaxies. The ATLAS3D surv…
A general basis set algorithm for galactic haloes and discs
E. J. Lilley, G. van de Ven
We present a unified approach to (bi-)orthogonal basis sets for gravitating systems. Central to our discussion is the notion of mutual gravitational energy, which gives rise to the…
On the robustness of triaxial Schwarzschild modelling: The effects of correcting the orbit mirroring
Sabine Thater, Prashin Jethwa, Behzad Tahmasebzadeh +13
In the past 15 years, the triaxial Schwarzschild orbit-superposition code by van den Bosch et al. (2008) has been widely applied to study the dynamics of galaxies. Recently, Quenne…
A two-parameter family of double-power-law biorthonormal potential-density expansions
E. J. Lilley, J. L. Sanders, N. W. Evans
Biorthonormal basis function expansions are widely used in galactic dynamics, both to study problems in galactic stability and to provide numerical algorithms to evolve collisionle…
Galaxy halo expansions: a new biorthogonal family of potential-density pairs
E. J. Lilley, J. L. Sanders, N. W. Evans +1
Efficient expansions of the gravitational field of (dark) haloes have two main uses in the modelling of galaxies: first, they provide a compact representation of numerically-constr…
