Spectral Distortions of the CMB as a Probe of Inflation, Recombination, Structure Formation and Particle Physics
J. Chluba, A. Kogut, S. P. Patil +98
Following the pioneering observations with COBE in the early 1990s, studies of the cosmic microwave background (CMB) have focused on temperature and polarization anisotropies. CMB…
Prior dependence of cosmological constraints on dark matter-radiation interactions
James A. D. Diacoumis, Yvonne. Y. Y. Wong
We explore the issue of prior dependence in the context of one-sided constraints on the dark matter-photon and dark matter-neutrino elastic scattering cross-sections derived from c…
Trading kinetic energy: How late kinetic decoupling of dark matter changes
James A. D. Diacoumis, Yvonne Y. Y. Wong
Elastic scattering between dark matter particles and a relativistic species such as photons or neutrinos leads to a transfer of energy from the latter due to their intrinsically di…
CMB spectral distortions as a novel way to probe the small-scale structure problems
James Diacoumis, Yvonne Wong
In this work we consider CMB spectral distortions as a probe of dark matter microphysics in the early universe. We demonstrate that future experiments such as PRISM have the potent…
Using CMB spectral distortions to distinguish between dark matter solutions to the small-scale crisis
James A. D. Diacoumis, Yvonne Y. Y. Wong
The dissipation of small-scale perturbations in the early universe produces a distortion in the blackbody spectrum of cosmic microwave background photons. In this work, we propose…
