Thick disk density profile from Koshimoto et al. (2021)

Attributes

R0float [kpc]

disk scale length

z0float [kpc]

disk scale height

rho0float [M_sum/kpc^3]

mass density at the solar position

Rbreakfloat [kpc]

distance within which surface density is flat

density_unit = 'mass'

rho0 = 2140000.0

z0 = 0.903

R0 = 2.2

Rbreak = 5.3

density(r: numpy.ndarray, phi_rad: numpy.ndarray, z: numpy.ndarray) → numpy.ndarray

Estimates the density at the given position

Parameters

rndarray [‘kpc’]

Distance to z axis

phi_radndarray [‘rad’]

azimuth angle of the stars. phi_rad = 0 is pointing towards sun.

z : height above the galactic plane (corrected for warp of the galaxy)

Returns

rhondarray [M_sun/kpc^3 or #/kpc^3]

density at the given location, either in number density evolved mass density or initial mass density should be specified in density_unit.
