redback.transient_models.tde_models.stream_stream_tde(time, redshift, mbh_6, mstar, c1, f, h_r, inc_tcool, del_omega, sigma_t, peak_time, **kwargs)

A TDE model based on stream-stream collisions. The early emission follows a constant temperature gaussian rise.

Parameters:

• time – observer frame time in days

• redshift – redshift

• mbh_6 – black hole mass (10^6 solar masses)

• mstar – mass of the disrupted star (solar masses)

• c1 – characteristic distance scale of the emission region in units of the apocenter distance of the most tightly bound debris

• f – fraction of the bound mass within the semimajor axis of the most tightly bound debris at peak mass return time

• h_r – aspect ratio used to calculate t_cool. This is only used when include_tcool_tdyn_ratio = 1

• inc_tcool – if include_tcool_tdyn_ratio = 1, the luminosity is limited by the Eddington luminosity if t_cool / t_dyn < 1.0

• del_omega – solid angle (in units of pi) of radiation from the emission region

• peak_time – peak time in days

• sigma_t – the sharpness of the Gaussian in 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 - ‘dynamics_output’, ‘flux_density’, or ‘magnitude’
