A multi-axion model of inflation and dark matter
Marcos A. G. Garcia, Hansel Gordillo-Ruiz, Raul Henriquez-Ortiz +1
Models with extra dimensions include a tower of massive states that unavoidably contribute to cosmological dynamics. In particular, after compactification, a higher-dimensional axi…
Spectral distortions in the decaying QCD dark matter scenario
Jorge Mastache, Raúl Henriquez-Ortiz
We study the QCD--DM scenario by analyzing the imprint of energy injection from decaying dark-sector particles on the spectral distortions (SDs) of the Cosmic Microwave Background…
Spectral Distortion Signatures of Step-like Inflationary Potential
Jorge Mastache, Wilson Barrera, Raúl Henríquez-Ortiz
In this work, we analyze a power-law inflationary potential enhanced with a step that can introduce features in the primordial power spectrum. We focus on the computation of the Sp…
Spectral distortions from promising single and multifield inflationary models
Alexander Baur, Marcos A. G. Garcia, Raul Henriquez-Ortiz +2
Forthcoming missions probing the absolute intensity of the CMB are expected to be able to measure spectral distortions, which are deviations from its blackbody distribution. As cos…
