Gauge Backreaction in Standard Model Warm Inflation
Rafid H. Dejrah, Anish Ghoshal
Standard-Model warm inflation (SMWI) makes QCD the microscopic origin of inflationary dissipation, so the real-time response of the gauge plasma enters the cosmological prediction.…
Induced Multi-phase Inflation with Reheating: Leptogenesis and Dark Matter Production in Metric versus Palatini
Nilay Bostan, Rafid H. Dejrah, Anish Ghoshal +1
We study non-minimally coupled scalar-induced multi-phase inflation in metric and Palatini gravity, considering linear, Brans-Dicke-like, and Higgs-like sectors. The scalar spectra…
WISPedia -- the WISPs Encyclopedia
Conrado Albertus, Francesca Chadha-Day, Arturo de Giorgi +8
The Weakly-Interacting Slim Particle encyclopedia (WISPedia) is a comprehensive reference work dedicated to the systematic compilation of theoretical models, Effective Field Theori…
Natural inflation in Palatini
N. Bostan, R. H. Dejrah, C. Dioguardi +1
Palatini gravity provides a robust framework for constructing viable inflationary potentials. In this study, we examine natural inflation and show that its consistency with…
Grand Unification Higgs- Inflation: Complementarity between Proton Decay and CMB Observables
Nilay Bostan, Rafid H. Dejrah, Anish Ghoshal
We propose a predictive Grand Unified Theory (GUT) framework for cosmic inflation in the Palatini formulation of gravity. In this model, a GUT Higgs field…
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.…
Gravity: Gravitational Waves Tests
Rafid H. Dejrah
This review explores modified theories of gravity, particularly gravity, as extensions to General Relativity (GR) that offer alternatives to dark energy for explaining cosmi…
A New Master Supernovae Ia sample and the investigation of the tension
M. G. Dainotti, B. De Simone, A. Garg +19
Modern cosmological research still thoroughly debates the discrepancy between local probes and the Cosmic Microwave Background observations in the Hubble constant (\texorpdfstring{…
Minimally coupled -exponential inflation with an term in the Palatini formulation
Nilay Bostan, Rafid H. Dejrah
We focus on the inflationary predictions of -exponential potential models, in which the inflaton is a representation of the field delineating the size of extra-dimension. Since…
