Compact objects in 4D Einstein Gauss Bonnet gravity: A data based perspective

Nuclear Physics B
Cosmic evolution is the most sensational topic among researchers of modern cosmology. This article explores cosmic evolution in 4D Einstein Gauss Bonnet gravity, focusing on mass accretion of compact objects (black holes and wormholes) by dark energy ...

Model-agnostic Cosmological Inference with SDSS-IV eBOSS: Simultaneous Probing for the Background and Perturbed Universe

The Astrophysical Journal
Here, we explore certain subtle features imprinted in data from the completed Sloan Digital Sky Survey IV (SDSS-IV) extended Baryon Oscillation Spectroscopic Survey (eBOSS) as a combined probe for the background and perturbed universe. We reconstruct the

LADDER: Revisiting the Cosmic Distance Ladder with Deep Learning Approaches and Exploring Its Applications

The Astrophysical Journal Supplement Series
We investigate the prospect of reconstructing the “cosmic distance ladder” of the Universe using a novel deep learning framework called LADDER —Learning Algorithm for Deep Distance Estimation and Reconstruction.

Constraining nonminimal fT gravity from Primordial Nucleosynthesis to Late-Universe observations

Results in Physics
We present a multi-epoch test of f(T) gravity with nonminimal torsion–matter coupling, combining early- and late-Universe observations. At the MeV scale, Big-Bang Nucleosynthesis constrains the fractional variation of the weak freeze-out temperature ...
