Primordial Black Holes Dark Matter and Secondary Gravitational Waves from Warm Higgs-G Inflation
Richa Arya, Rajeev Kumar Jain, Arvind Kumar Mishra
We explore the role of dissipative effects during warm inflation leading to the small-scale enhancement of the power spectrum of curvature perturbations. In this paper, we specific…
Scalar Induced Gravitational Waves from Warm Inflation
Richa Arya, Arvind Kumar Mishra
Stochastic gravitational waves can be induced from the primordial curvature perturbations generated during inflation, through scalar-tensor mode coupling at the second order of cos…
Formation of Primordial Black Holes from Warm Inflation
Richa Arya
Primordial Black Holes (PBHs) serve as a unique probe to the physics of the early Universe, particularly inflation. In light of this, we study the formation of PBHs by the collapse…
Study of warm inflationary models and their parameter estimation from CMB
Richa Arya, Raghavan Rangarajan
Observations of the temperature anisotropies in the Cosmic Microwave Background (CMB) radiation show that the models of inflation with the monomial potentials are inconsistent with…
Revisiting CMB constraints on Warm Inflation
Richa Arya, Arnab Dasgupta, Gaurav Goswami +2
We revisit the constraints that Planck 2015 temperature, polarization and lensing data impose on the parameters of warm inflation. To this end, we study warm inflation driven by a…
Gravitino production in a thermal Universe revisited
Richa Arya, Namit Mahajan, Raghavan Rangarajan
We study the production of spin 1/2 gravitinos in a thermal Universe. Taking into account supersymmetry breaking due to the finite thermal energy density of the Universe, there is…
