Journal ArticleDOI

Cosmology Intertwined: A Review of the Particle Physics, Astrophysics, and Cosmology Associated with the Cosmological Tensions and Anomalies

Elcio Abdalla, +202 more
TL;DR: In this paper , the authors focus on the 5.0σ tension between the Planck CMB estimate of the Hubble constant H0 and the SH0ES collaboration measurements and discuss the importance of trying to fit a full array of data with a single model.
Journal ArticleDOI

A CMB search for the neutrino mass mechanism and its relation to the Hubble tension

TL;DR: In this article, the authors investigate potential imprints in the cosmic microwave background (CMB) arising from massive majorons, should they thermalize with neutrinos after Big Bang Nucleosynthesis via inverse neutrino decays.
Journal ArticleDOI

A CMB Search for the Neutrino Mass Mechanism and its Relation to the $H_0$ Tension

TL;DR: In this article, the authors investigate potential imprints in the Cosmic Microwave Background (CMB) arising from massive majorons, should they thermalize with neutrinos after Big Bang Nucleosynthesis via inverse neutrino decays.
Journal ArticleDOI

Detecting the stimulated decay of axions at radio frequencies

TL;DR: In this article, it was shown that the presence of an ambient radiation field leads to a stimulated enhancement of the decay rate; depending on the environment and the mass of the axion, the effect of stimulated emission may amplify the photon flux by serval orders of magnitude.
Journal ArticleDOI

Cosmological evolution of light dark photon dark matter

TL;DR: In this paper, the role of nonresonant absorption, which has previously been neglected in cosmological studies of this dark matter candidate, produces strong constraints on dark photon dark matter with mass as low as
