redback.sed.CutoffBlackbody

class redback.sed.CutoffBlackbody(time: ndarray, temperature: ndarray, luminosity: ndarray, r_photosphere: ndarray, frequency: float | ndarray, luminosity_distance: float, cutoff_wavelength: float, absorption_index: float = 1.0, **kwargs: None)[source]

Bases: _SED

__init__(time: ndarray, temperature: ndarray, luminosity: ndarray, r_photosphere: ndarray, frequency: float | ndarray, luminosity_distance: float, cutoff_wavelength: float, absorption_index: float = 1.0, **kwargs: None) → None[source]

Blackbody SED with a cutoff

Parameters:

  • time – time in source frame

  • temperature – temperature in kelvin

  • luminosity – luminosity in cgs

  • r_photosphere – photosphere radius in cm

  • frequency – frequency in Hz - must be a single number or same length as time array

  • luminosity_distance – dl in cm

  • cutoff_wavelength – cutoff wavelength in Angstrom

  • absorption_index – power-law index for UV suppression below cutoff_wavelength. Flux below cutoff scales as (cutoff_wavelength/wavelength)^absorption_index relative to a blackbody. Default is 1.0 (Nicholl+2017 nominal value for SLSNe).

  • kwargs – None

__call__(**kwargs)

Call self as a function.
