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…
Gravitation Wave signal from Asteroid mass Primordial Black Hole Dark Matter
Diptimoy Ghosh, Arvind Kumar Mishra
Primordial Black Holes (PBHs) in the mass range g are currently unconstrained, and can constitute the full Dark Matter (DM) density of the universe. Motivate…
Energizing gamma ray bursts via mediated neutrino heating
Tanmay Kumar Poddar, Srubabati Goswami, Arvind Kumar Mishra
The pair annihilation of neutrinos can energize violent stellar explosions such as gamma ray bursts (GRBs). The energy in this neutrino heating me…
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…
Exploring the Self Interacting Dark Matter Properties From Low Redshift Observations
Arvind Kumar Mishra
The small scale observations indicate that the dark matter may be self-interacting. In this paper, we calculate the shear () and bulk viscosity () of Self Interacting Dark Ma…
Viscous dark matter and 21 cm cosmology
Jitesh R. Bhatt, Arvind Kumar Mishra, Alekha C. Nayak
The EDGES experiment has detected the global absorption signal of 21 cm line at in cosmic dawn era and reported its amplitude larger than the standard cosmological predic…
Viscous Self Interacting Dark Matter Cosmology For Small Redshift
Abhishek Atreya, Jitesh R. Bhatt, Arvind Kumar Mishra
The viscosity of dark matter in cosmological models may cause an accelerated expansion and when this effect is sufficiently large, it can explain the dark energy. In this work, att…
Viscous Self Interacting Dark Matter and Cosmic Acceleration
Abhishek Atreya, Jitesh R. Bhatt, Arvind Mishra
Self interacting dark matter (SIDM) provides us with a consistent solution to certain astrophysical observations in conflict with collision-less cold DM paradigm. In this work we e…
