Luminosity-Dependent Variations in the Secondary Maximum of Type Ia Supernovae and Their Connection to Host Galaxy Morphology
Jagriti Gaba, Rahul Kumar Thakur, Dinkar Verma +2
Type Ia supernovae (SNe Ia) are considered standardizable candles and are therefore important probes of the universe's expansion history and cosmic distances. In comparison to the…
Investigating The Hubble Tension Through Hubble Parameter Data
Rahul Kumar Thakur, Shashikant Gupta, Rahul Nigam +1
The Hubble constant (), which represents the expansion rate of the Universe, is one of the most important cosmological parameters. The recent measurements of using the d…
Constant-Roll Inflation in modified gravity model using Palatini Formalism
Sukanta Panda, Arun Rana, Rahul Thakur
In this work, we study a constant-roll inflationary model in the Palatini formalism using modified gravity. Here our action consists a non-minimal coupling of a scalar field wi…
Investigating the Hubble Tension: Effect of Cepheid Calibration
Rahul Kumar Thakur, Harish Kumar, Shashikant Gupta +2
Recent observations of Type Ia supernovae (SNe) by SH0ES collaboration (R11 and R16) diverge from the value reported by recent CMBR observations utilising the Planck satellite and…
Inflation with antisymmetric tensor field: new candidates
Sandeep Aashish, Abhijith Ajith, Sukanta Panda +1
We study classes of inflation models driven by antisymmetric tensor field, with minimal and nonminimal couplings to gravity, that address known issues of such models considered in…
Cosmological Analysis using Panstarrs data: Hubble Constant and Direction Dependence
Rahul Kumar Thakur, Meghendra Singh, Shashikant Gupta +1
Hubble tension and the search for preferred direction are two crucial unresolved issues in modern cosmology. Different measurements of the Hubble constant provide significantly dif…
