Both foreground stars and dSph stars are generated by instantiating a class object of GenerateDSPH and GenerateForeground, both of which are contained for reference in dSph_Model.py. Testing_Script.py is included to show what the foreground stars look like, along with some important distributions, and dSph data maybe be generated using Generate_Galaxies.py. dSph generation maybe be used with multi-threading but is unimplemented as of yet for foreground stars. Best of luck with all your astrophysical endeavors.
There are two versions of the simulation software Genesis.py and Genesis Burkert.py. Genesis.py produces a database of simulated dSph galaxies with a random selection of Burkert DM density profiles of NFW DM density profiles. The manipulation of the underlying parameters can be done in the if name ==’ main ’ section, begin- ning at line 318, of the software, where the variable num galaxy (line 321) determines the number of galaxies that will be produced and can be set to the desired num- ber. The Burkert profile parameters are governed by the arrays r core array (line 326) and rho central array (line 327) which determine the core radius and central halo density distributions respectively. The NFW profile parameter distributions are defined by c param array (line 330) and M 200 array (line 331) which determine the concentration parameter and the virial mass distributions respectively. These free parameters can be adjusted to produce the galaxy profiles desired. The anisotropy of the galaxies is controlled by the variable beta array (line 334), and the distance to the galaxy is defined by the distribution contained in the variable D array (line 335), all of which can be adjusted to suit the needs of the simulation. Moving into the for loop on line 337, the various parameters are for the stellar density, luminosity, anisotropy, and distance to the star are defined in the first lines of the loop and can be adjusted appropriately. The variable N on line 344 defines the number of stars that are produced in each galaxy and can be set to the desired number. Lines 353-358 randomly choose either a Burkert DM density profile or an NFW DM density profile, and the following if statements after the profile is selected are where the functions to generate the galaxies are called. The variable save path on line 397 establishes the path to the folder where the .csv files containing the galaxies will be stored and can be adjusted accordingly. The variable save location on line 403 creates the .csv files where the data will be saved and the filepath should be adjusted similarly to the save path filepath. The lines following write the data to the .csv file and save the data. To run the simulation software simply adjust the above parameters to the desired values or ranges and run the software in an IDE or from the command line.
