Cosmological implications of f(T, B) gravity: constraints from recent observations
Laxmipriya Pati, Santosh V. Lohakare, S. K. Maurya
In this work, we examine the theoretical framework of modified teleparallel gravity with the inclusion of the boundary term in the action and investigate its cosmological implicati…
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.…
Exploring the stability of cosmology near general relativity limit with different connections
María-José Guzmán, Laur Järv, Laxmipriya Pati
In this work, we study cosmological spacetime configurations in gravity with nonvanishing symmetric teleparallel connections. It is known that the spatially flat, homogeneou…
Stability of symmetric teleparallel scalar-tensor cosmologies with alternative connections
Laur Jarv, Laxmipriya Pati
In symmetric teleparallel geometry the curvature and torsion tensors are assumed to vanish identically, while the dynamics of gravity is encoded by nonmetricity. Here the spatially…
Hamilton's equations in the covariant teleparallel equivalent of general relativity
Laxmipriya Pati, Daniel Blixt, Maria-Jose Guzman
We present Hamilton's equations for the teleparallel equivalent of general relativity (TEGR), which is a reformulation of general relativity based on a curvatureless, metric compat…
Evolutionary behaviour of cosmological parameters with dynamical system analysis in f (Q, T) gravity
Laxmipriya Pati, S. A. Narawade, S. K. Tripathy +1
We have investigated the accelerating behaviour of the universe in gravity in an isotropic and homogeneous space-time. We have initially derive the dynamical parameters in…
Dynamical system analysis for accelerating models in non-metricity gravity
S. A. Narawade, Laxmipriya Pati, B. Mishra +1
Two accelerating cosmological models are presented in symmetric teleparallel gravity, be the non-metricity. The models are constructed based on the assumptions of two di…
Electromagnetic neural source imaging under sparsity constraints with SURE-based hyperparameter tuning
Pierre-Antoine Bannier, Quentin Bertrand, Joseph Salmon +1
Estimators based on non-convex sparsity-promoting penalties were shown to yield state-of-the-art solutions to the magneto-/electroencephalography (M/EEG) brain source localization…
Matter Bounce Scenario and the Dynamical aspects in f(Q,T) Gravity
A. S. Agrawal, Laxmipriya Pati, S. K. Tripathy +1
In the context of the late time cosmic acceleration phenomenon, many geometrically modified theories of gravity have been proposed in recent times. In this paper, we have investiga…
Model parameters in the context of late time cosmic acceleration in gravity
Laxmipriya Pati, B. Mishra, S. K. Tripathy
The dynamical aspects of some accelerating models are investigated in the framework of an extension of symmetric teleparllel gravity dubbed as f(Q,T) gravity. In this gravity theor…
