Particle Dark Matter constraints: The effect of Galactic uncertainties
(2017-02-02)
Collider, space, and Earth based experiments are now able to probe several extensions of the Standard Model of particle physics which provide viable dark matter candidates. Direct and indirect dark matter searches rely on ...
Can dark matter be a scalar field?
(Iop Publishing Ltd, 2016-08-01)
In this paper we study a real scalar field as a possible candidate to explain the dark matter in the universe. In the context of a free scalar field with quadratic potential, we have used Union 2.1 SN Ia observational data ...
Structure formation in inhomogeneous Early Dark Energy models
(IOP Publishing, 2020)
Search for dark sector by repurposing the UVX Brazilian synchrotron
(Institute for Ionics, 2023-06)
We propose the first Search for Dark Sector at the Brazilian Synchrotron Light Laboratory, site of Sirius, a fourth-generation storage ring. We show that UVX, Sirius predecessor, can be a promising dark sector detector, ...
Clustering dark energy and halo abundances

Relic abundance of mass-varying cold dark matter particles
(Elsevier B.V., 2005-09-29)
In models of coupled dark energy and dark matter the mass of the dark matter particle depends on the cosmological evolution of the dark energy field. In this Letter we exemplify in a simple model the effects of this mass ...
Signature of the interaction between dark energy and dark matter in observations
(AMER PHYSICAL SOC, 2010)
We investigate the effect of an interaction between dark energy and dark matter upon the dynamics of galaxy clusters. This effect is computed through the Layser-Irvine equation, which describes how an astrophysical system ...
Holographic field theory models of dark energy in interaction with dark matter
(AMER PHYSICAL SOCCOLLEGE PK, 2012)
We discuss two Lagrangian interacting dark energy models in the context of the holographic principle. The potentials of the interacting fields are constructed. The models are compared with CMB distance information, baryonic ...
THE ROLE OF DARK MATTER INTERACTION IN GALAXY CLUSTERS
(WORLD SCIENTIFIC PUBL CO PTE LTDSINGAPORE, 2012)
We consider a toy del to analyze the consequences of dark matter interaction with a dark energy background on the overall rotation of galaxy clusters and the misalignment between their dark matter and baryon distributions ...
Self-interacting holographic dark energy
(World Scientific, 2013-01)
We investigate a spatially flat Friedmann–Robertson–Walker (FRW) universe where dark matter exchanges energy with a self-interacting holographic dark energy (SIHDE). Using the χ 2 -statistical method on the Hubble function, ...
