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…
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…
Constraints on Cosmology with Pantheon+
Rebecca Briffa, Celia Escamilla-Rivera, Jackson Levi Said +1
cosmology has shown promise in explaining aspects of cosmic evolution. In this work, we analyze constraints on leading models of gravity in the context of the recentl…
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…
