SFH sampling (sfh)

The sfh module covers classes for a variety of models for the galactic star formation history, each of which inherits from StarFormationHistory class. You can read more about each of these models below.

Classes

StarFormationHistory(**kwargs)	Class for a generic galactic star formation history model from which to sample
CompositeStarFormationHistory(components, ...)	A star formation history that is a combination of multiple other star formation histories.
DistributionFunctionBasedSFH(potential[, df])	A star formation history based on a distribution function.
Wagg2022([tsfr, alpha, Fm, gradient, Rnow, ...])	A semi-empirical model defined in Wagg+2022 (see Figure 1 and Section 2.2.1 for a detailed explanation.), heavily based on Frankel+2018.
Frankel2018SFH([scale_length, scale_height, ...])	A star formation history for a component of the Milky Way, based on Frankel+2018.
LowAlphaDiscWagg2022(**kwargs)	A star formation history for the low-alpha disc of the Milky Way, used in Wagg+2022
HighAlphaDiscWagg2022(**kwargs)	A star formation history for the high-alpha disc of the Milky Way, used in Wagg+2022
BulgeWagg2022(**kwargs)	A star formation history for the bulge of the Milky Way used in Wagg+2022
MilkyWayBarSormani2022(potential[, kappa, ...])	A star formation history for the Milky Way bar, based on Sormani+2022.
BurstUniformDisc([t_burst, z_max, R_max, Z_all])	An extremely simple star formation history, with all stars formed at t_burst in a uniform disc with height z_max and radius R_max disc, all with metallicity Z.
ConstantUniformDisc([t_burst, z_max, R_max, ...])	A simple star formation history, with all stars formed at a constant rate between t_burst and the present day in a uniform disc with height z_max and radius R_max disc, all with metallicity Z.
ConstantPlummerSphere(tau_min, tau_max, ...)	A simple star formation history, with all stars formed at a constant rate between tau_min and tau_max in a Plummer sphere potential, all with metallicity Z.
SandersBinney2015(potential[, time_bins, ...])	Star formation history model based on a Quasi-Isothermal Disc distribution function from Sanders & Binney 2015.
SpheroidalDwarf(J_0_star, alpha, eta, ...[, ...])	An action-based model for dwarf spheroidal galaxies and globular clusters Pascale+2019.
CarinaDwarf(**kwargs)	A model for the Carina dwarf spheroidal galaxy based on Pascale+2019.

Functions

load(file_name[, key])	Load an entire class from storage.
concat(*sfhs)	Concatenate multiple StarFormationHistory objects together.
