Primordial Black Hole Formation in a Dust Bouncing Model
E. J. Barroso, L. F. Demétrio, S. D. P. Vitenti +1
Linear scalar cosmological perturbations have increasing spectra in the contracting phase of bouncing models. We study the conditions for which these perturbations may collapse int…
APES: Approximate Posterior Ensemble Sampler
Sandro Dias Pinto Vitenti, Eduardo J. Barroso
This paper proposes a novel approach to generate samples from target distributions that are difficult to sample from using Markov Chain Monte Carlo (MCMC) methods. Traditional MCMC…
The catalog-to-cosmology framework for weak lensing and galaxy clustering for LSST
J. Prat, J. Zuntz, Y. Omori +20
We present TXPipe, a modular, automated and reproducible pipeline for ingesting catalog data and performing all the calculations required to obtain quality-assured two-point measur…
CLMM: a LSST-DESC Cluster weak Lensing Mass Modeling library for cosmology
M. Aguena, C. Avestruz, C. Combet +22
We present the v1.0 release of CLMM, an open source Python library for the estimation of the weak lensing masses of clusters of galaxies. CLMM is designed as a standalone toolkit o…
Cosmological constant constraints from observation-derived energy condition bounds and their application to bimetric massive gravity
M. E. S. Alves, F. C. Carvalho, J. C. N. de Araujo +2
Among the various possibilities to probe the theory behind the recent accelerated expansion of the universe, the energy conditions (ECs) are of particular interest, since it is pos…
A general reconstruction of the recent expansion history of the universe
S. D. P. Vitenti, M. Penna-Lima
Distance measurements are currently the most powerful tool to study the expansion history of the universe without specifying its matter content nor any theory of gravitation. Assum…
