Gauge invariant perturbations of Cosmology
Shivam Kumar Mishra, Jackson Levi Said, B. Mishra
The Gauss-Bonnet invariant connects foundational aspects of geometry with physical phenomena in a variety of ways. Teleparallel gravity offers a novel direction in which to use the…
Hubble Tension and Dark Energy in Teleparallel Gauss-Bonnet Gravity: New Constraints from DESI BAO, Pantheon and Hubble Data
Santosh V. Lohakare, S. K. Maurya, Aaisha Al Qassabi +1
We explore the cosmological dynamics of a teleparallel Gauss-Bonnet gravity model defined by the torsion scalar and the torsion-based Gauss-Bonnet invariant ,…
Propagating Gravitational Waves in Teleparallel Gauss-Bonnet Gravity
Shivam Kumar Mishra, Jackson Levi Said, B. Mishra
Gravitational waves offer a key insight into the viability of classes of gravitational theories beyond general relativity. The observational constraints on their speed of propagati…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
