Non-Markovian Cosmology with Causal Memory Kernels
Aritra Sanyal, Prabir Rudra
We investigate a non-Markovian extension of Friedmann cosmology in which the present expansion rate retains information about the past cosmic evolution through a causal memory kern…
Evolving wormhole cosmology: modified Friedmann dynamics and observational constraints
Aritra Sanyal, Kazuharu Bamba, Prabir Rudra
We construct an evolving wormhole cosmological model from a Morris--Thorne metric with a separable, time-dependent shape function in a spatially flat Friedmann--Lemaitre--Robertson…
Interplay of Holographic and New Agegraphic Dark Energy in Cosmology: A hybrid dark energy model from a generalized length-time cut-off
Sayani Maity, Aritra Sanyal, Prabir Rudra
The spatial and temporal infrared cutoffs are the source of the Holographic dark energy (HDE) and New Agegraphic dark energy (NADE) models, respectively. Inspired by the spacetime…
Ricci-Cubic Holographic Dark Energy: Confronting Observations, Stability and the Cosmic Coincidence Problem
Aritra Sanyal, Prabir Rudra
In this work, we constrain the parameter space of the Ricci-Cubic Holographic Dark Energy (RCHDE) model using several observational datasets, including Hubble parameter measurement…
Gravitational waves driven by Holographic dark energy
Sayani Maity, Prabir Rudra
In this paper, we have studied the effects of holographic dark energy on the evolution of gravitational waves. The background evolution of gravitational waves in a flat FRW univers…
Gravitational Collapse of Bose-Einstein condensate dark matter in Generalized Vaidya spacetime
Prabir Rudra
In this work, we study the gravitational collapse procedure in generalized Vaidya spacetime with Bose-Einstein condensate dark matter density profile. We use the generalized Vaidya…
A Cosmological Holographic Reconstruction of f(Q) Theory
Pameli Saha, Prabir Rudra
This paper explores a cosmological reconstruction scheme in the background of f(Q) gravity theory from a Holographic perspective. The basic motivation for this work is that the rec…
Warm Inflation with Barrow Holographic Dark Energy
Moli Ghosh, Prabir Rudra, Surajit Chattopadhyay +1
In this work, we study the warm inflation mechanism in the presence of the Barrow holographic dark energy model. Warm inflation differs from other forms of inflation primarily in t…
The effects of the pole dark energy on gravitational waves
Homa Shababi, Sayani Maity, Prabir Rudra +1
In this paper, we have studied the effects of pole dark energy on the evolution of gravitational waves. The background evolution of gravitational waves in a flat FRW universe is co…
Gravitational Collapse in Energy-momentum squared gravity: Nature of singularities
Prabir Rudra
In this paper, we explore a collapsing scenario in the background of energy-momentum squared gravity (EMSG). EMSG claims to have terms that originate from the quantum gravity effec…
