Do low-redshift observations open the doors to an open universe?
Deng Wang, Olga Mena, Salvatore Capozziello +1
The detection of a significant deviation from a zero curvature would have profound consequences for inflationary theories and fundamental physics. Relative to high-redshift Planck'…
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…
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…
An emulation-based model for the projected correlation function
Vetle A. Vikenes, Cheng-Zong Ruan, David F. Mota
Data from the ongoing \textit{Euclid} survey will map out billions of galaxies in the Universe, covering more than a third of the sky. This data will provide a wealth of informatio…
Generic Predictions for Primordial Perturbations and their implications
Mohit K. Sharma, M. Sami, David F. Mota
We introduce a novel framework for studying small-scale primordial perturbations and their cosmological implications. The framework uses a deep reinforcement learning to generate s…
The slingshot effect as a probe of transverse motions of galaxies
R. Hagala, C. Llinares, D. F. Mota
There are currently no reliable methods to measure transverse velocities of galaxies. This is an important piece of information that could allow us to probe the physics of structur…
Primordial Magnetic Fields via Spontaneous Breaking of Lorentz Invariance
O. Bertolami, D. F. Mota
Spontaneous breaking of Lorentz invariance compatible with observational limits may realistically take place in the context of string theories, possibly endowing the photon with a…
