redback.transient_models.supernova_models.csm_nickel(time, redshift, mej, f_nickel, csm_mass, ek, eta, rho, kappa, r0, **kwargs)[source]

Assumes csm and nickel engine with homologous expansion

Parameters:

  • time – time in days in observer frame

  • redshift – source redshift

  • mej – ejecta mass in solar masses

  • csm_mass – csm mass in solar masses

  • ek – kinetic energy in ergs

  • eta – csm density profile exponent

  • rho – csm density profile amplitude

  • kappa – opacity

  • r0 – radius of csm shell in AU

  • kwargs – kappa_gamma, temperature_floor, and any kwarg to change any other input physics/parameters from default.

  • 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’
