Publication Info This repository contains a set of specialized mathematical routines that correspond to the publication at https://arxiv.org/abs/2004.07792 Publication Info

Libraries and Routines SSSStateGenerator.py contains the necessary functionality to produce solutions to the spherically symmetric and static Einstein Klein Gordon Equations.
EDIT THIS FILE AT YOUR OWN RISK, the majority of the other routines depend on the format of this file. We STRONGLY SUGGEST read chapter 3 and the appendix of the arxiv publication listed above before making any edits.

SPARCRotationCurves.py and SPARCTullyFisherRelation.py provide a PANDAS dataframe of the relevant observational data from the SPARC survey - further details of SPARC can be found in these files.

DiskFractionSolver.py is a routine that corresponds to Chapter 3 of the arxiv publication.
This will take the dark matter only states from the SSSStateSolver package, and use a continuation method to include the effects of ordinary visible matter.

BoundaryProblemSolver.py will apply a scaling relationship to a family of solutions and output a new set of solutions with a tully-fisher like trend. This corersponds to the Amplitude-Wavelength boundary condtion from the publication.

TullyFisherFittingRoutine.py contains a simplified routine that combines the entirety of this repository to produce a basic fit to the observed BTFR.
Libraries and Routines

RUNTIME NOTICE** The routines contained in this repository can take an extremely long time to resolve and converge to their final results. The runtime will increase quadratically with the total number of static states calculated. Computations of the first 100 states can take upwards of 48 hours RUNTIME NOTICE****
