Disentangling the primordial nature of stochastic gravitational wave backgrounds with CMB spectral distortions
Bryce Cyr, Thomas Kite, Jens Chluba +5
The recent detection of a stochastic gravitational wave background (SGWB) at nanohertz frequencies by pulsar timing arrays (PTAs) has sparked a flurry of interest. Beyond the stand…
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…
Bridging the Gap: Spectral Distortions meet Gravitational Waves
Thomas Kite
This talk has the goal of introducing two upcoming exciting avenues of discovery in precision Cosmology: spectral distortions (SDs) and gravitational waves (GWs). The former signal…
Clarifying transfer function approximations for the large-scale gravitational wave background in CDM
Thomas Kite, Jens Chluba, Andrea Ravenni +1
The primordial gravitational wave background (GWB) offers an exciting future avenue of discovery for new physics. Its information content encodes multiple eras in the early Univers…
Bridging the gap: spectral distortions meet gravitational waves
Thomas Kite, Andrea Ravenni, Subodh P. Patil +1
Gravitational waves (GWs) have the potential to probe the entirety of cosmological history due to their nearly perfect decoupling from the thermal bath and any intervening matter a…
