Gala - v1.6.1

Changelog included below:

New Features

• Added a .replicate() method to Potential classes to enable copying potential objects but modifying some parameter values.

• Added a new potential class MN3ExponentialDiskPotential based on Smith et al. (2015): an approximation of the potential generated by a double exponential disk using a sum of three Miyamoto-Nagai disks.

• The Orbit.estimate_period() method now returns period estimates in all phase-space components instead of just the radial period.

• Added a store_all flag to the integrators to control whether to save phase-space information for all timesteps or only the final timestep.

• Added a plot_rotation_curve() method to all potential objects to make a 1D plot of the circular velocity curve.

• Added a new potential for representing multipole expansions MultipolePotential.

• Added a new potential CylSplinePotential for flexible representation of axisymmetric potentials by allowing passing in grids of potential values evaluated grids of R, z values (like the CylSpline potential in Agama).

• Added a show_time flag to Orbit.animate() to control whether to show the current timestep.

• Changed Orbit.animate() to allow for different marker_style and segment_style options for individual orbits by passing a list of dicts instead of just a dict.

• Added an experimental new class SCFInterpolatedPotential that accepts a time series of coefficients and interpolates the coefficient values to any evaluation time.

Bug fixes

• Fixed a bug where the NFWPotential energy was nan when evaluating at the origin, and added tests for all potentials to check for a finite value of the potential at the origin (when expected).

• Fixed a bug in NFWPotential.from_M200_c() where the incorrect scale radius was computed (Cython does not always use Python 3 division rules for dividing integers!).

• Fixed a bug in the (C-level/internal) estimation of the 2nd derivative of the potential, used to generate mock streams, that affects non-conservative force fields.

API changes

• The Orbit.estimate_period() method now returns period estimates in all phase-space components instead of just the radial period.

gala is an Astropy-affiliated Python package for galactic dynamics. Python enables wrapping low-level languages (e.g., C) for speed without losing flexibility or ease-of-use in the user-interface. The API for gala was designed to provide a class-based and user-friendly interface to fast (C or Cython-optimized) implementations of common operations such as gravitational potential and force evaluation, orbit integration, dynamical transformations, and chaos indicators for nonlinear dynamics. gala also relies heavily on and interfaces well with the implementations of physical units and astronomical coordinate systems in the Astropy package (astropy.units and astropy.coordinates).
