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…
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…
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…
