Benchmarking Exact, GP-Emulated, and Simulation-Based Inference for Late-Time Cosmology
Sai Swagat Mishra
Forthcoming cosmological surveys require inference pipelines that are both statistically reliable and computationally scalable. In this work, we perform a systematic comparison of…
Kinematic Probes of Type-II MMG: Padé Cosmographic Analysis of VCDM
Soumya Kanta Bhoi, Sai Swagat Mishra, P. K. Sahoo
We study the late-time expansion history of the Universe within the VCDM model, a Type-II MMG realization that preserves the successes of General Relativity while extending beyond…
Exploring Late-Time Cosmic Acceleration in VCDM Cosmology
Sai Swagat Mishra, Soumya Kanta Bhoi, P. K. Sahoo
In this work, we have considered a minimally modified gravity theory that effectively reproduces VCDM-like behavior to investigate its cosmological implications. The model paramete…
BBN to Late-Time Acceleration in Gravity
Sai Swagat Mishra, Suchita Patel, P. K. Sahoo
We present, to our knowledge, the first systematic study of early-late cosmic evolution and acceleration in the framework of gravity, an extension of teleparal…
Cosmological Evolution of the Universe in Torsion-based Modified Gravity
Sai Swagat Mishra
General Relativity, despite its century-long success, faces conceptual and observational challenges, including singularities, incompatibility with quantum mechanics, and the need t…
Observational constraints on viscous free- fluid in gravity
Simran Arora, Sai Swagat Mishra, P. K. Sahoo
We study the late-time cosmological dynamics of a spatially flat FLRW universe in the framework of gravity, where denotes the nonmetricity scalar. The matter sector is m…
