Single field matter bounce with dark energy era: comparison with CMB Planck 2018 data and best fit parameters
Rodrigo F. Pinheiro, Nelson Pinto-Neto
In this work, we perform Markov Chain Monte Carlo (MCMC) analyses using the Planck 2018 cosmic microwave background (CMB) datasets, including temperature, polarization, and lensing…

Cosmological forecast from the full-sky angular power spectrum and bispectrum of 21cm intensity mapping
Rodrigo F. Pinheiro, André A. Costa, Yu Sang
We compute the full-sky angular power spectrum and bispectrum, along with their Fisher matrices, to forecast constraints on cosmological parameters for the BINGO and SKA1-MID Band…
