Modeling the 3-point correlation function of projected scalar fields on the sphere
Abraham Arvizu, Alejandro Aviles, Juan Carlos Hidalgo +5
One of the main obstacles for the signal extraction of the three point correlation function using photometric surveys, such as the Rubin Observatory Legacy Survey of Space and Time…
fkPT: Constraining scale-dependent modified gravity with the full-shape galaxy power spectrum
Mario A. Rodriguez-Meza, Alejandro Aviles, Hernan E. Noriega +4
Modified gravity models with scale-dependent linear growth typically exhibit an enhancement in the power spectrum beyond a certain scale. The conventional methods for extracting co…
A hybrid model of viscous and Chaplygin gas to tackle the Universe acceleration
A. Hernández-Almada, Miguel A. García-Aspeitia, M. A. Rodrírgues-Meza +1
Motivated by two seminal models proposed to explain the Universe acceleration, this paper is devoted to study a hybrid model which is constructed through a generalized Chaplygin ga…
Redshift space power spectrum beyond Einstein-de Sitter kernels
Alejandro Aviles, Georgios Valogiannis, Mario A. Rodriguez-Meza +3
We develop a framework to compute the redshift space power spectrum (PS), with kernels beyond Einstein-de Sitter (EdS), that can be applied to a wide variety of generalized cosmolo…
Nonlinear evolution of initially biased tracers in modified gravity
Alejandro Aviles, Mario Alberto Rodriguez-Meza, Josue De-Santiago +1
In this work we extend the perturbation theory for modified gravity (MG) in two main aspects. First, the construction of matter overdensities from Lagrangian displacement fields is…
A scalar field dark matter model and its role in the large scale structure formation in the Universe
Mario A. Rodriguez-Meza
In this work we present a model of dark matter based on scalar-tensor theory of gravity. With this scalar field dark matter model we study the non-linear evolution of the large sca…
Power spectrum of large-scale structure cosmological models in the framework of scalar-tensor theories
M. A. Rodriguez-Meza
We study the large-scale structure formation in the Universe in the frame of scalar-tensor theories as an alternative to general relativity. We review briefly the Newtonian limit o…
Cosmological simulations: the role of scalar fields
M. A. Rodriguez-Meza
We present numerical -body simulation studies of large-scale structure formation. The main purpose of these studies is to analyze the several models of dark matter and the role…
The influence of scalar fields in protogalactic interactions
M. A. Rodriguez-Meza, J. Klapp, J. L. Cervantes-Cota +1
We present simulations within the framework of scalar-tensor theories, in the Newtonian limit, to investigate the influence of massive scalar fields on the dynamics of the collisio…
