micrOMEGAs 7: Beyond standard cosmology
G. Belanger, A. Belyaev, N. Bernal +4
We present micrOMEGAs7, a major upgrade of the micrOMEGAs package for the computation of dark matter observables in generic models. This release introduces a generalized treatment…
From Rags to Jeans: Axion Miniclusters from Early matter domination
Ariel Angulo, Paola Arias, Nicolás Bernal +1
In an early matter-dominated era, density and temperature inhomogeneities of the radiation bath grow more efficiently than in the standard radiation-dominated history. If the axion…
Next-to-Minimal Freeze-in Dark Matter
Nicolás Bernal, Sagnik Mukherjee, James Unwin
If the dark matter mass exceeds the highest temperature of the thermal bath, then dark matter production is Boltzmann suppressed. This opens new possibilities for dark matter model…
Strongly interacting singlet scalar dark matter during reheating
Geneviève Bélanger, Nicolás Bernal, Alexander Pukhov
We revisit the singlet scalar dark matter model in the presence of a non-standard cosmological history prior to radiation domination. We focus on the regime in which the relic abun…
Probing Bose-enhanced Inflaton Decay with Gravitational Waves
Nicolás Bernal, Quan-feng Wu, Xun-Jie Xu +1
We investigate cosmic reheating dynamics in the presence of a transient condensate formed by bosonic decay products of the inflaton. We show that the emergence of such a condensate…
