SUNBIRD : a simulation-based model for full-shape density-split clustering
Combining galaxy clustering information from regions of different environmental densities can help break cosmological parameter degeneracies and access non-Gaussian information from the density field that is not readily captured by the standard two-point c ...
2024MeV-scale seesaw and leptogenesis
Marco Drewes, Valerie Fiona Domcke, Michele Lucente
We study the type-I seesaw model with three right-handed neutrinos and Majorana masses below the pion mass. In this mass range, the model parameter space is not only strongly constrained by the requirement to explain the light neutrino masses, but also by ...
SPRINGER2021Constraints on dark matter to dark radiation conversion in the late universe with DES-Y1 and external data
Eduardo Sanchez, Jonathan Andrew Blazek
We study a phenomenological class of models where dark matter converts to dark radiation in the low redshift epoch. This class of models, dubbed DMDR, characterizes the evolution of comoving dark-matter density with two extra parameters, and may be able to ...
