Cosmology-informed Neural Networks to infer dark energy equation-of-state
Anshul Verma, Shashwat Sourav, Pavan K. Aluri +1
We present a framework that combines physics-informed neural networks (PINNs) with Markov Chain Monte Carlo (MCMC) inference to constrain dynamical dark energy models using the Pan…
Probing foreground residuals in cleaned CMB temperature maps from Planck
Sanjeet K. Patel, Pavan K. Aluri, Pranati K. Rath +1
Maps of cosmic microwave background (CMB) are extracted from multi-frequency observations using a variety of cleaning procedures. However, in regions of strong microwave emission,…
Examining statistical isotropy of CMB low multipoles from Planck PR4 data
Pavan Kumar Aluri, Sanjeet Kumar Patel
Low multipoles () in cosmic microwave background (CMB) temperature anisotropies have shown some `peculiarities' when examined since the release of the full sky CMB maps, using a…
Cosmographic constraints on a Gödel-type rotating universe
Anshul Verma, Pavan K. Aluri, David F. Mota +1
We investigate the possibility of global cosmic rotation using a Gödel-type rotating cosmological model, constrained through a cosmographic analysis of Type Ia supernovae (SNIa) fr…
