Non-parametric reconstruction of cosmological observables using Gaussian Processes Regression
José de Jesús Velázquez, Luis A. Escamilla, Purba Mukherjee +1
The current accelerated expansion of the Universe remains ones of the most intriguing topics in modern cosmology, driving the search for innovative statistical techniques. Recent a…
Do we need wavelets in the late Universe?
Luis A. Escamilla, Emre Özülker, Özgür Akarsu +2
We parameterize the Hubble function by adding Hermitian wavelets to the Hubble radius of CDM. This allows us to build Hubble functions that oscillate around CDM at late times…
Cosmology on a Gravitational Wave Background
Tonatiuh Matos, Luis A. Escamilla, Maribel Hernández +1
It is a fact that the universe lives on a Gravitational Wave Background (GWB), which it may be in the form of extra energy, which is not contained in Einstein's field equations. In…
Classification algorithms applied to structure formation simulations
Jazhiel Chacón, J. Alberto Vázquez, Erick Almaraz
Throughout cosmological simulations, the properties of the matter density field in the initial conditions have a decisive impact on the features of the structures formed today. In…
Core-Halo Mass Relation in Scalar Field Dark Matter Models and its Consequences for the Formation of Supermassive Black Holes
Luis E. Padilla, Tanja Rindler-Daller, Paul R. Shapiro +2
Scalar-field dark matter (SFDM) halos exhibit a core-envelope structure with soliton-like cores and CDM-like envelopes. Simulations without self-interaction (free-field case) repor…
Bayesian model selection on Scalar -Field Dark Energy
J. Alberto Vázquez, David Tamayo, Anjan A. Sen +1
The main aim of this paper is to analyse minimally-coupled scalar-fields -- quintessence and phantom -- as the main candidates to explain the accelerated expansion of the universe…
A simple estimation of the size of the molecules using a pencil lead
Ricardo Medel-Esquivel, Isidro Gómez-Vargas, J. Alberto Vázquez +1
The main aim of this article is that students, at the basic level of education, gain a quantitative understanding of the size of molecules by performing a simple experiment easily…
Constraining the dark energy equation of state using Bayes theorem and the Kullback-Leibler divergence
S. Hee, J. A. Vázquez, W. J. Handley +2
Data-driven model-independent reconstructions of the dark energy equation of state are presented using Planck 2015 era CMB, BAO, SNIa and Lyman- data. These reconstructio…
