redback.transient_models.spectral_models.powerlaw_plus_blackbody_spectrum_at_z(angstroms, redshift, pl_amplitude, pl_slope, pl_evolution_index, temperature_0, radius_0, temp_rise_index, temp_decline_index, temp_peak_time, radius_rise_index, radius_decline_index, radius_peak_time, time, **kwargs)[source]

A powerlaw + blackbody spectrum at a given redshift and time, properly accounting for redshift effects.

Parameters:

  • angstroms – wavelength array in angstroms in obs frame

  • redshift – source redshift

  • pl_amplitude – power law amplitude at reference wavelength at t=1 day (erg/s/cm^2/Angstrom)

  • pl_slope – power law slope (F_lambda ∝ lambda^slope)

  • pl_evolution_index – power law time evolution F_pl(t) ∝ t^(-pl_evolution_index)

  • temperature_0 – initial blackbody temperature in Kelvin at t=1 day (rest frame)

  • radius_0 – initial blackbody radius in cm at t=1 day (rest frame)

  • temp_rise_index – temperature rise T(t) ∝ t^temp_rise_index for t < temp_peak_time

  • temp_decline_index – temperature decline T(t) ∝ t^(-temp_decline_index) for t > temp_peak_time

  • temp_peak_time – time in days when temperature peaks

  • radius_rise_index – radius rise R(t) ∝ t^radius_rise_index for t < radius_peak_time

  • radius_decline_index – radius decline R(t) ∝ t^(-radius_decline_index) for t > radius_peak_time

  • radius_peak_time – time in days when radius peaks

  • time – time in observer frame in days

  • kwargs – Additional parameters

  • reference_wavelength – wavelength for power law amplitude normalization in Angstroms (default 5000)

  • cosmology – Cosmology object for luminosity distance calculation

  • component – ‘combined’ (default), ‘blackbody’, or ‘powerlaw’ to return individual components

Returns:

flux in ergs/s/cm^2/angstrom in obs frame
