FIRst Extragalactic Simulation Of Neutrinos and Gamma-rays.
Documentation for the astrophysics and cosmology of neutrino sources can be found on:

FIRESONG depends on cosmolopy, numpy and scipy. Set up the enviromental variable FIRESONG. In bash: export FIRESONG=/location/of/firesong/.
Several scripts are provided:
- Firesong.py - Generates an instance of all neutrino sources in the Universe according to the parameters provided (e.g. local neutrino source density). Both the flux and the redshift of neutrino sources are calculated.
- FluxPDF.py - Generated the flux probability density distribution of a source. It complements FIRESONG.py because is it much faster for large source densities. Only the flux of neutrino sources is calculated.
- Legend.py - Generates an instance of gamma-ray sources in the universe according to a luminosity denpendent density evolution (LDDE). Both the redshift and the gamma-ray flux (without attenuation) are calculated.
Examples:
- A muon neutrino diffuse flux saturation example:
python Firesong.py -d 1e-6 --evolution CC2015SNR --zmax 4.0
--fluxnorm 1.44e-8 --index 2.28 --LF SC
wlll simulate neutrino sources with a local density of 10^-6 Mpc^-3 with a source denstiy evolution that folows the Clash and Candels 2015 Supernova Rate (CC2015SNR). The simulation will be done up to a redshift of 4.0. The neutrino luminosity, because it is not specified as an option, will be calculated internally to saturate a muon neutrino diffuse flux with a normalization, at 100 TeV, of E^2d\phi/dE = 1.44 x 10^-8 GeV.cm^-2.s^-1.sr^-1 and with a spectral index of -2.28. Neutrino luminosoty is distributed as a delta function, i.e., standard candle (SC).
- An exploration of the luminosity vs. local density plane (aka Kowalski plot) example:
python Firesong.py -d 1e-6 --evolution MD2016SFR --zmax 8.0
--index 2.28 --LF SC -L 1e51
wlll simulate neutrino sources with a local density of 10^-6 Mpc^-3 with a source denstiy evolution that folows the Madau and Dickinson 2016 Star Formation Rate History (MD2014SFR). The simulation will be done up to a redshift of 8.0. The neutrino power law spectral index is -2.28. Neutrino luminosoty is distributed as a delta function, i.e., standard candle (SC) and is set to be 10^51 erg/year. Note that muon neutrino diffuse flux normalization is ignored when a luminosity is specified, but the spectral index should still be provided. This mode of operation allows the exploration of the luminosity vs. local density plane (aka Kowalski plot).
All unittest could be run by
