Weak Lensing Effect on CMB in the Presence of a Dipole Anisotropy
Abhineet Agarwal, Naveen K. Singh, Pankaj Jain +1
We investigate weak lensing effect on cosmic microwave background (CMB) in the presence of dipole anisotropy. The approach of flat-sky approximation is considered. We determine the…
Quintessential Inflation and curvaton reheating
Abhineet Agarwal, Sabit Bekov, Kairat Myrzakulov
In this paper, we consider a model of quintessential inflation based upon inverse hyperbolic potential. We employ curvaton mechanism for reheating which is more efficient than grav…
Cosmic acceleration from coupling of baryonic and dark matter components: Analysis and diagnostics
Abhineet Agarwal, R. Myrzakulov, S. K. J. Pacif +1
In this paper, we examine a scenario in which late-time cosmic acceleration might arise due to the coupling between baryonic matter and dark matter without the presence of extra de…
Cosmic acceleration sourced by modification of gravity without extra degrees of freedom
Abhineet Agarwal, R. Myrzakulov, S. K. J. Pacif +2
In this paper, we investigate a scenario in which late time cosmic acceleration might arise due to coupling between dark matter and baryonic matter without resorting to dark energy…
Quintessential Inflation in a thawing realization
Abhineet Agarwal, R. Myrzakulov, M. Sami +1
We study quintessential inflation with an inverse hyperbolic type potential , where , and "n" are parameters of the theory…
diagnostic applied to scalar field models and slowing down of cosmic acceleration
M. Shahalam, Sasha Sami, Abhineet Agarwal
We apply the diagnostic to models for dark energy based on scalar fields. In case of the power law potentials, we demonstrate the possibility of slowing down the expansion of…
Thermal Tachyacoustic Cosmology
Abhineet Agarwal, Niayesh Afshordi
An intriguing possibility that can address pathologies in both early universe cosmology (i.e. the horizon problem) and quantum gravity (i.e. non-renormalizability), is that particl…
