Model-independent calibration of Gamma-Ray Bursts with neural networks
Purba Mukherjee, Maria Giovanna Dainotti, Konstantinos F. Dialektopoulos +2
The Cold Dark Matter (CDM) cosmological model has been highly successful in predicting cosmic structure and evolution, yet recent precision measurements have highlighted dis…
A possible late-time transition of inferred via neural networks
Purba Mukherjee, Konstantinos F. Dialektopoulos, Jackson Levi Said +1
The strengthening of tensions in the cosmological parameters has led to a reconsideration of fundamental aspects of standard cosmology. The tension in the Hubble constant can also…
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…
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…
Strengthening extended Gravity constraints with combined systems: bounds from Cosmology and the Galactic Center
D. Benisty, J. Mifsud, J. Levi Said +1
Extended gravity is widely constrained in different astrophysical and astronomical systems. Since these different systems are based on different scales it is not trivial to get a c…
Dark energy by natural evolution: Constraining dark energy using Approximate Bayesian Computation
Reginald Christian Bernardo, Daniela Grandón, Jackson Levi Said +1
We look at dark energy from a biology inspired viewpoint by means of the Approximate Bayesian Computation (ABC) and late time cosmological observations. We find that dynamical dark…
