Journal ArticleDOI

Freeze-in production of FIMP dark matter

TL;DR: In this paper, the authors propose an alternate, calculable mechanism of dark matter genesis, "thermal freeze-in", involving a Feebly Interacting Massive Particle (FIMP) interacting so feebly with the thermal bath that it never attains thermal equilibrium.
Journal ArticleDOI

Big bang nucleosynthesis constraints on hadronically and electromagnetically decaying relic neutral particles

TL;DR: In this paper, the decay times of decaying relic neutral particles with decay times in the interval 0.01sec and 0.10sec were examined. But the decay time of decaying particle masses was not considered.
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

Evolution of cosmic magnetic fields: From the very early Universe, to recombination, to the present

TL;DR: In this paper, a detailed examination of the evolution of stochastic magnetic fields between high cosmic temperatures and the present epoch is presented, and a simple analytical model matching the results of the 3D MHD simulations allows for the prediction of present day magnetic field correlation lengths and energy.
Journal ArticleDOI

Did something decay, evaporate, or annihilate during Big Bang nucleosynthesis?

TL;DR: In this paper, a detailed examination of the cascade nucleosynthesis resulting from the putative hadronic decay, evaporation, or annihilation of a primordial relic during the big bang nucleosynthetic (BBN) era is presented.
