Stable bouncing solutions in Teleparallel Horndeski gravity: violations of the no-go theorem
Bobomurat Ahmedov, Konstantinos F. Dialektopoulos, Jackson Levi Said +3
In order to have singularity-free solutions at the beginning of the Universe, we need to violate the null energy condition. In the general class of Horndeski gravity, there are hea…
Cosmological singularities in gravity
Oem Trivedi, Maxim Khlopov, Jackson Levi Said +1
The pursuit of understanding the mysteries surrounding dark energy has sparked significant interest within the field of cosmology. While conventional approaches, such as the cosmol…
Growth of structures using redshift space distortion in Cosmology
Rebecca Briffa, Celia Escamilla-Rivera, Jackson Levi Said +1
Cosmology faces a pressing challenge with the Hubble constant () tension, where the locally measured rate of the Universe's expansion does not align with predictions from the…
Neural network reconstruction of scalar-tensor cosmology
Konstantinos F. Dialektopoulos, Purba Mukherjee, Jackson Levi Said +1
Neural networks have shown great promise in providing a data-first approach to exploring new physics. In this work, we use the full implementation of late time cosmological data to…
Exploring the Growth Index : Insights from Different CMB Dataset Combinations and Approaches
Enrico Specogna, Eleonora Di Valentino, Jackson Levi Said +1
In this study we investigate the growth index , which characterizes the growth of linear matter perturbations, while analysing different cosmological datasets. We compare the…
Neural network reconstruction of cosmology using the Pantheon compilation
Konstantinos F. Dialektopoulos, Purba Mukherjee, Jackson Levi Said +1
In this work, we reconstruct the Hubble diagram using various data sets, including correlated ones, in Artificial Neural Networks (ANN). Using ReFANN, that was built for data sets…
