redback.transient_models.supernova_models.homologous_expansion_supernova
- redback.transient_models.supernova_models.homologous_expansion_supernova(time, redshift, mej, ek, **kwargs)[source]
Assumes homologous expansion to transform kinetic energy to ejecta velocity
- Parameters:
time – time in days in observer frame
redshift – source redshift
mej – ejecta mass in solar masses
ek – kinetic energy in ergs
kwargs – Must be all the kwargs required by the specific interaction_process, photosphere, sed methods used e.g., for Diffusion and TemperatureFloor: kappa, kappa_gamma, vej (km/s), temperature_floor ‘base model’ from homologous_expansion_models list
interaction_process – Default is Diffusion. Can also be None in which case the output is just the raw engine luminosity, or another interaction process.
photosphere – Default is TemperatureFloor. kwargs must have vej or relevant parameters if using different photosphere model
sed – Default is blackbody.
frequency – Required if output_format is ‘flux_density’. frequency to calculate - Must be same length as time array or a single number).
bands – Required if output_format is ‘magnitude’ or ‘flux’.
output_format – ‘flux_density’, ‘magnitude’, ‘spectra’, ‘flux’, ‘sncosmo_source’
lambda_array – Optional argument to set your desired wavelength array (in Angstroms) to evaluate the SED on.
cosmology – Cosmology to use for luminosity distance calculation. Defaults to Planck18. Must be a astropy.cosmology object.
- Returns:
set by output format - ‘flux_density’, ‘magnitude’, ‘spectra’, ‘flux’, ‘sncosmo_source’
