One Feature, Three Clocks: Phase-Locked Gravitational Waves, Primordial Black Holes, and Non-Gaussianity from Periodic Warm Inflation
Mayukh R. Gangopadhyay
A shift-symmetric inflaton dissipating into a thermal bath couples to that bath periodically, so its friction oscillates as the field rolls. We follow what this does to warm inflat…
Constraining Quintessential Inflation with ACT: A Gauss-Bonnet Gateway
Yogesh, Imtiyaz Ahmad Bhat, Mayukh R. Gangopadhyay +1
Recent results from the Atacama Cosmology Telescope (ACT), indicating a higher and more tightly constrained scalar spectral index, , place several inflatio…
Warm Inflation Beyond the Markovian Limit
Mayukh R. Gangopadhyay, Nilanjana Kumar
Warm inflation is commonly studied under the assumption that the stochastic force sourcing inflaton fluctuations is Markovian. Realistic thermal systems, however, possess finite re…
Primordial Black Hole Formation in Rastall Gravity: Shifted Collapse Threshold and Exponential Abundance Sensitivity
Mayukh R. Gangopadhyay
Primordial black holes formed in the early universe are compelling candidates for dark matter. We investigate their production in Rastall gravity, a modification of general relativ…
Constraining Anisotropic Universe Through Big Bang Nucleosynthesis: A Case Study of The Bianchi Type-I Universe
Jiwon Park, Sourav Mridha, Dukjae Jang +2
The isotropy and homogeneity of our Universe are the cardinal principles of modern cosmology built on the definition of metric through the prescription by Friedmann-Lematr…
Inflationary Dynamics in Einstein-Gauss-Bonnet Gravity Using New Slow-Roll Approximations considering Generalised Reheating
Yogesh, Imtiyaz Ahmad Bhat, Mayukh R. Gangopadhyay
The Cosmic Microwave Background (CMB) observations results reported by {\it Planck} satellite suggest a plateau characteristic in the flat potential of the inflaton field is favore…
