Restoration of dark-soliton pulses
(John Wiley & Sons IncNew York, 1996)
Can dark matter–dark energy interaction alleviate the cosmic coincidence problem?
(2022-03-01)
In this paper we study a model of interacting dark energy–dark matter where the ratio between these components is not constant, changing from early to late times in such a way that the model can solve or alleviate the ...
Search for sharp and smooth spectral signatures of μν SSM gravitino dark matter with Fermi-LAT
(IOP Publishing, 2017-03)
The μνSSM solves the μ problem of supersymmetric models and reproduces neutrino data, simply using couplings with right-handed neutrinos ν's. Given that these couplings break explicitly R parity, the gravitino is a natural ...
Properties of subhalos in the interacting dark matter scenario
(Multidisciplinary Digital Publishing Institute, 2019-09-21)
One possible and natural derivation fromthe collisionless cold dark matter (CDM) standard cosmological framework is the assumption of the existence of interactions between dark matter (DM) and photons or neutrinos. Such a ...
New geometries for the characterization of dark matter phenomena
(2014)
We present some new geometries with spheroidal symmetry, with and without mass, that involve new kind of energy momentum tensors, and which are suitable for the description of dark matter phenomena.
Scaling attractors in interacting teleparallel dark energy
(2013-07-01)
It has been proposed recently the existence of a non-minimal coupling between a canonical scalar field (quintessence) and gravity in the framework of teleparallel gravity, motivated by similar constructions in the context ...

Entropy and creation cold dark matter models
(2019-01-01)
Entropy is a fundamental concept from thermodynamics, and it can be used to study models in the context of the creation cold dark matter. A general feature of these models is that thermodynamic equilibrium is reached at ...
Forecasts for warm dark matter from photometric galaxy surveys
(2018-11-01)
We present a Fisher matrix forecast for the sensitivity on the mass of a thermal warm dark matter (WDM) particle from current (DES-like) and future (LSST-like) photometric galaxy surveys using the galaxy angular power ...
