Spectro-spatial evolution of the CMB III: transfer functions, power spectra and Fisher forecasts
Thomas Kite, Andrea Ravenni, Jens Chluba
In this paper, we provide the first computations for the distortion transfer functions of the cosmic microwave background (CMB) in the perturbed Universe, following up on paper I a…

Spectro-spatial evolution of the CMB II: generalised Boltzmann hierarchy
Jens Chluba, Andrea Ravenni, Thomas Kite
In this paper, we formulate a generalised photon Boltzmann hierarchy that allows us to model the evolution and creation of spectral distortion anisotropies in the early Universe. W…

Spectro-spatial evolution of the CMB I: discretisation of the thermalisation Green's function
Jens Chluba, Thomas Kite, Andrea Ravenni
Spectral distortions of the cosmic microwave background (CMB) have been recognized as an important future probe of the early Universe. Existing theoretical studies primarily focuse…
