Extended Dark Energy analysis using DESI DR2 BAO measurements
K. Lodha, R. Calderon, W. L. Matthewson +122
We conduct an extended analysis of dark energy constraints, in support of the findings of the DESI DR2 cosmology key paper, including DESI data, Planck CMB observations, and three…
Snowmass2021 Cosmic Frontier White Paper: Prospects for obtaining Dark Matter Constraints with DESI
Monica Valluri, Solene Chabanier, Vid Irsic +29
Despite efforts over several decades, direct-detection experiments have not yet led to the discovery of the dark matter (DM) particle. This has led to increasing interest in altern…
One-parametric description for scalar field dark matter potentials
Francisco X. Linares Cedeño, L. Arturo Ureña-López
We study the cosmological evolution for a scalar field dark matter model, by considering a parameterization of the evolution equations that allow us to unify in a single parameter…
Nonlinear cosmological structure with ultralight bosons via modified gravity
Stefany G. Medellin-Gonzalez, L. Arturo Urena-Lopez, Alma X. Gonzalez-Morales
Ultra-light bosons as dark matter has become a model of major interest in Cosmology, due to the possible imprint of a distinct signature in the cosmic structure both at the linear…
Scalar field dark matter with a cosh potential, revisited
L. Arturo Ureña-López
Dark matter models in which the constituent particle is an ultra-light boson have become part of the mainstream discussion in cosmology and astrophysics. At the classical level, th…
Unbiased constraints on ultralight axion mass from dwarf spheroidal galaxies
Alma X. Gonzalez-Morales, David J. E. Marsh, Jorge Peñarrubia +1
It has been suggested that the internal dynamics of dwarf spheroidal galaxies (dSphs) can be used to test whether or not ultralight axions with are a pr…
Formation of subhorizon black holes from preheating
E. Torres-Lomas, Juan Carlos Hidalgo, Karim A. Malik +1
We study the production of primordial black holes (PBHs) during the preheating stage that follows a chaotic inflationary phase. The scalar fields present in the process are evolved…
Non-relativistic approach for cosmological Scalar Field Dark Matter
L. Arturo Urena-Lopez
We derive non-relativistic equations of motion for the formation of cosmological structure in a Scalar Field Dark Matter (SFDM) model corresponding to a complex scalar field endowe…
Primordial black hole production during preheating in a chaotic inflationary model
E. Torres-Lomas, L. Arturo Urena-Lopez
In this paper we review the production of primordial black holes (PBHs) during preheating after a chaotic inflationary model. All relevant equations of motion are solved numericall…
Interacting viscous dark fluids
Arturo Avelino, Yoelsy Leyva, L. Arturo Urena-Lopez
We revise the conditions for the physical viability of a cosmological model in which dark matter has bulk viscosity and also interacts with dark energy. We have also included radia…
Hints on halo evolution in SFDM models with galaxy observations
Alma X. Gonzalez-Morales, Alberto Diez-Tejedor, L. Arturo Urena-Lopez +1
A massive, self-interacting scalar field has been considered as a possible candidate for the dark matter in the universe. We present an observational constraint to the model arisin…
Unified description of the dynamics of quintessential scalar fields
L. Arturo Urena-Lopez
Using the dynamical system approach, we describe the general dynamics of cosmological scalar fields in terms of critical points and heteroclinic lines. It is found that critical po…
Unification models with reheating via primordial black holes
J. C. Hidalgo, L. Arturo Urena-Lopez, Andrew R. Liddle
We study the possibility of reheating the universe through the evaporation of primordial black holes created at the end of inflation. This is shown to allow for the unification of…
Dynamics of Scalar Field Dark Matter With a Cosh-like Potential
Tonatiuh Matos, Jose-Ruben Luevano, Israel Quiros +2
The dynamics of a cosmological model fueled by scalar field dark matter with a cosh-like potential plus a cosmological constant is investigated in detail. It is revealed that the l…
