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…
Testing the theory of gravity with DESI: estimators, predictions and simulation requirements
Shadab Alam, Christian Arnold, Alejandro Aviles +33
Shortly after its discovery, General Relativity (GR) was applied to predict the behavior of our Universe on the largest scales, and later became the foundation of modern cosmology.…
Modeling the Marked Spectrum of Matter and Biased Tracers in Real- and Redshift-Space
Oliver H. E. Philcox, Alejandro Aviles, Elena Massara
We present the one-loop perturbation theory for the power spectrum of the marked density field of matter and biased tracers in real- and redshift-space. The statistic has been show…
Impact of cosmological signatures in two-point statistics beyond the linear regime
Dante V. Gomez-Navarro, Alexander Mead, Alejandro Aviles +1
Some beyond CDM cosmological models have dark-sector energy densities that suffer phase transitions. Fluctuations entering the horizon during such a transition can receive enhan…
Cosmological signatures of a Rapid Diluted Energy Density
Axel de la Macorra, Dante V. Gomez-Navarro, Alejandro Aviles +3
We study the cosmological signatures of having extra energy density, , beyond the CDM model that dilutes rapidly, faster than radiation, at a scale factor with a c…
A Lagrangian Perturbation Theory in the presence of massive neutrinos
Alejandro Aviles, Arka Banerjee
We develop a Lagrangian Perturbation Theory (LPT) framework to study the clustering of cold dark matter (CDM) in cosmologies with massive neutrinos. We follow the trajectories of C…
