Checking the second law at cosmic scales
Narayan Banerjee, Purba Mukherjee, Diego Pavón
Based on recent data about the history of the Hubble factor, it is argued that the second law of thermodynamics holds at the largest scales accessible to observation. This is consi…
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…
Role of Future SNIa Data from Rubin LSST in Reinvestigating Cosmological Models
Rahul Shah, Ayan Mitra, Purba Mukherjee +2
We study how future Type-Ia supernovae (SNIa) standard candles detected by the Vera C. Rubin Observatory (LSST) can constrain some cosmological models. We use a realistic three-yea…
Reconstructing the Hubble parameter with future Gravitational Wave missions using Machine Learning
Purba Mukherjee, Rahul Shah, Arko Bhaumik +1
We study the prospects of Gaussian processes (GP), a machine learning (ML) algorithm, as a tool to reconstruct the Hubble parameter with two upcoming gravitational wave miss…
Examining the validity of the minimal varying speed of light model through cosmological observations: relaxing the null curvature constraint
Purba Mukherjee, Gabriel Rodrigues, Carlos Bengaly
We revisit a consistency test for the speed of light variability, using the latest cosmological observations. This exercise can serve as a new diagnostics for the standard cosmolog…
A thorough investigation of the prospects of eLISA in addressing the Hubble tension: Fisher Forecast, MCMC and Machine Learning
Rahul Shah, Arko Bhaumik, Purba Mukherjee +1
We carry out an in-depth analysis of the capability of the upcoming space-based gravitational wave mission eLISA in addressing the Hubble tension, with a primary focus on observati…
Spatial Curvature and Thermodynamics
Narayan Banerjee, Purba Mukherjee, Diego Pavón
Reasonable parametrizations of the current Hubble data set of the expansion rate of our homogeneous and isotropic universe, after suitable smoothing of these data, strongly suggest…
