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…
