Primordial Black Hole Formation in Dust-Radiation Bouncing Cosmologies
Xuan Ye, Luiz Felipe Demetrio, Eduardo Jose Barroso +2
Primordial black holes (PBHs) provide a unique probe of the early Universe and may have an enhanced abundance in bouncing cosmologies, where a long contracting phase can amplify pe…
Weak lensing mass-richness relation of redMaPPer clusters in the LSST DESC DC2 simulations
Constantin Payerne, Zhuowen Zhang, Michel Aguena +13
Cluster scaling relations are key ingredients in cluster abundance-based cosmological studies. In optical cluster cosmology, where clusters are detected through their richness, clu…
AutoKnots: Adaptive Knot Allocation for Spline Interpolation
Sandro D. P. Vitenti, Fernando de Simoni, Mariana Penna-Lima +1
In astrophysical and cosmological analyses, the increasing quality and volume of astronomical data demand efficient and precise computational tools. This work introduces a novel ad…
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…
