Dark energy, scalar singlet dark matter and the Higgs portal
Ricardo G. Landim
One of the simplest extensions of the Standard Model (SM) comprises the inclusion of a massive real scalar field, neutral under the SM gauge groups, to be a dark matter candidate.…
Cosmic Transients, Einstein's Equivalence Principle and Dark Matter Halos
Orfeu Bertolami, Ricardo G. Landim
Cosmic transients, such as gamma-ray bursts and fast radio bursts, have been used to constrain the Einstein's Equivalence Principle (EEP) through the parametrized-post-Newtonian (P…
Interacting dark energy in the dark model
Ricardo G. Landim, Rafael J. F. Marcondes, Fabrízio F. Bernardi +1
We explore the cosmological implications of the interactions among the dark particles in the dark model. It turns out that the relevant interaction is between dark energy…
Dark Sector Cosmology
Ricardo C. G. Landim
The dark side of the universe is mysterious and its nature is still unknown. In fact, this poses perhaps as the biggest challenge in the modern cosmology. The two components of the…
