dust_sobs

interferopy.tools.dust_sobs(nu_obs, z, mass_dust, temp_dust, beta, cmb_contrast=True, cmb_heating=True)[source]

Compute observed flux density of the dust continuum, assuming a modified black body.

Parameters

  • nu_obs – Observed frame frequency in Hz.

  • z – Redshift of the source.

  • mass_dust – Total dust mass in kg.

  • temp_dust – Intrinsic dust temperature in K (the source would have at z=0).

  • beta – Emissivity coefficient, dimensionless.

  • cmb_contrast – Correct for cosmic microwave background contrast.

  • cmb_heating – Correct for cosmic microwave background heating (important at high z where Tcmb ~ Tdust).

Returns

Observed flux density in W/Hz/m^2.
