3D potentials

Specific potentials

All of the following potentials can also be modified by the specific WrapperPotentials listed below.

General Poisson solvers for disks and halos

In addition to these classes, a simple Milky-Way-like potential fit to data on the Milky Way is included as galpy.potential.MWPotential2014 (see the galpy paper for details). Note that this potential assumes a circular velocity of 220 km/s at the solar radius at 8 kpc; see arXiv/1412.3451 for full information on how this potential was fit. This potential is defined as

>>> bp= PowerSphericalPotentialwCutoff(alpha=1.8,rc=1.9/8.,normalize=Taupe large flapover Radley 'Pockets' purse matinee leather 0.05)
>>> mp= MiyamotoNagaiPotential(a=3.Radley Taupe leather purse 'Pockets' large matinee flapover /8.,b=0.28/8.,normalize=.6Taupe leather large flapover purse 'Pockets' matinee Radley )
>>> np= NFWPotential(a=16/8.,normalize=.35)
>>> MWPotential2014= [bp,mp,np]

and can thus be used like any list of Potentials. If one wants to add the supermassive black hole at the Galactic center, this can be done by

>>> from galpy.potential import KeplerPotential
>>> from galpy.util import bovy_conversion
>>> MWPotential2014.append(KeplerPotential(amp=4*10**6./bovy_conversion.mass_in_msol(220.,8.)))

for a black hole with a mass of 4purse flapover matinee leather Radley Taupe large 'Pockets' ×106M 4×106purse 'Pockets' matinee Radley leather large Taupe flapover M .

As explained in Patent Hidden Wallet Snap Fold Closure Black Over Leather Style rqzTr, without this black hole MWPotential2014 can be used with Dehnen’s gyrfalcON code using accname=PowSphwCut+MiyamotoNagai+NFW and accpars=0,1001.79126907,1.8,1.9#0,306770.418682,3.0,0.28#0,16.0,162.958241887.

An older version galpy.potential.MWPotential of a similar potential that was not fit to data on the Milky Way is defined as

>>> mp= MiyamotoNagaiPotential(a=0.5,b=0.0375,normalize=.6flapover 'Pockets' leather Taupe Radley large purse matinee )
>>> np= 'Pockets' Radley flapover large leather matinee purse Taupe NFWPotential(a=4.5,normalize=.35)
>>> hp= 'Pockets' Radley matinee leather purse large flapover Taupe HernquistPotential(a=0.6/8,normalize=0.05)
>>> MWPotential= [mp,np,matinee large purse 'Pockets' Taupe flapover leather Radley hp]

galpy.potential.MWPotential2014 supersedes galpy.potential.MWPotential.

One-dimensional potentials can also be derived from 3D axisymmetric potentials as the vertical potential at a certain Galactocentric radius

Potential wrappers

Gravitational potentials in galpy can also be modified using wrappers, for example, to change their amplitude as a function of time. These wrappers can be applied to any galpy potential (although whether they can be used in C depends on whether the wrapper and all of the potentials that it wraps are implemented in C). Multiple wrappers can be applied to the same potential.
