redback.transient_models.tde_models.fitted_pl_decay(time, redshift, log_mh, a_bh, m_disc, r0, tvi, t_form, incl, log_L, t_decay, p, log_T, sigma_t, t_peak, **kwargs)[source]

An import of FitTeD to model the plateau phase, with a gaussian rise and power-law decay

Parameters:

  • time – observer frame time in days

  • redshift – redshift

  • log_mh – log of the black hole mass (solar masses)

  • a_bh – black hole spin parameter (dimensionless)

  • m_disc – initial mass of disc ring (solar masses)

  • r0 – initial radius of disc ring (gravitational radii)

  • tvi – viscous timescale of disc evolution (days)

  • t_form – time of ring formation prior to t = 0 (days)

  • incl – disc-observer inclination angle (radians)

  • log_L – single temperature blackbody amplitude for decay model (log_10 erg/s)

  • t_decay – fallback timescale (days)

  • p – power-law decay index

  • log_T – single temperature blackbody temperature for decay model (log_10 Kelvin)

  • sigma_t – gaussian rise timescale (days)

  • t_peak – time of light curve peak (days)

  • kwargs – Must be all the kwargs required by the specific output_format

  • output_format – ‘flux_density’, ‘magnitude’, ‘spectra’, ‘flux’, ‘sncosmo_source’

  • 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’.

  • 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’
