cTreeBalls: a fast 3-point correlation function code for clustering measurements
Mario A. Rodriguez-Meza, Eladio Moreno, Alejandro Aviles +1
cTreeBalls (cBalls for short) is a Python/C package useful to measure (2,3)-point clustering statistics. cBalls can efficiently calculate 3-point correlations of more than 200 mill…
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…
