Inflationary models in a minimally coupled gravity: Constraints from , BICEP/, and ACT
Biswajit Deb, Atri Deshamukhya
The advent of high-precision cosmological observations has challenged many traditional inflationary models. Data from 2018 along with the BICEP/ 2018 result have alr…
Warm Inflation in a Braneworld Scenario
Sabina Yeasmin, Atri Deshamukhya
In the literature, many warm inflationary models are formulated. In this piece of work, a warm inflationary model in the braneworld scenario is studied, considering constant and va…
Inflation in f(R,T) gravity with Double-Well potential
Biswajit Deb, Atri Deshamukhya
In this piece of work, we studied the inflation in the context of theory of gravity. We assumed the functional form of to be , where R is the R…
Slow-roll Natural & Hilltop Inflation in Rastall Gravity
Isaac M. Vitohekpon, Biswajit Deb, Ines G. Salako +2
This study provides a concise analysis of inflation under Rastall gravity by examining three types of potential such as the power law, natural, and hilltop potentials. Choosing a m…
Quasinormal Modes, Grebody Factors, and Hawking Radiation Sparsity of Black Holes Influenced by a Global Monopole Charge in Kalb-Ramond Gravity
Anshuman Baruah, Yassine Sekhmani, Sunil Kumar Maurya +2
Kalb-Ramond (KR) gravity is an intriguing model incorporating local Lorentz violation, and black hole (BH) solutions are known to exist. In this study, we investigate some crucial…
Constraining logarithmic model using Dark Energy density parameter and Hubble parameter
Biswajit Deb, Atri Deshamukhya
Of many extended theories of gravity, gravity has gained reasonable interest in recent times as it provides interesting results in cosmology. Logarithmic corrections in mo…
