Published in 2020 at "Astrophysics and Space Science"

DOI: 10.1007/s10509-020-03766-w

Abstract: Extended Red Emission (ERE) is a widely observed optical emission process, present in a wide range of circumstellar and interstellar environments in the Milky Way galaxy as well as other galaxies. Definitive identifications of the… read more here.

Published in 2017 at "Surveys in Geophysics"

DOI: 10.1007/s10712-017-9452-0

Abstract: Cloud profiling from active lidar and radar in the A-train satellite constellation has significantly advanced our understanding of clouds and their role in the climate system. Nevertheless, the response of clouds to a warming climate… read more here.

Published in 2018 at "Indian Journal of Physics"

DOI: 10.1007/s12648-017-1126-8

Abstract: Cosmological model with viscous generalized Chaplygin gas (in short, VGCG) is considered here to determine observational constraints on its equation of state parameters (in short, EoS) from background data. These data consists of $$H(z)-z$$H(z)-z (OHD)… read more here.

Published in 2021 at "Geophysical Research Letters"

DOI: 10.1029/2020gl092309

Abstract: Uncertainty in climate feedbacks is the primary source of the spread in projected surface temperature responses to anthropogenic forcing. Cloud feedback persistently appears as the main source of disagreement in future projections while the combined… read more here.

Published in 2020 at "Physical Review D"

DOI: 10.1103/physrevd.102.084005

Abstract: In this paper we study the observational constraints that can be imposed on the coupling parameter, $\hat \alpha$, of the recently proposed 4-dimensional Einstein-Gauss-Bonnet theory of gravity. We consider the field equations that can be… read more here.

Published in 2018 at "Physical Review D"

DOI: 10.1103/physrevd.97.043503

Abstract: The recent GW170817 measurement favors the simplest dark energy models, such as a single scalar field. Quintessence models can be classified in two classes, freezing and thawing, depending on whether the equation of state decreases… read more here.

Published in 2018 at "Physical Review D"

DOI: 10.1103/physrevd.98.063510

Abstract: We perform a detailed confrontation of various oscillating dark-energy parame-trizations with the latest sets of observational data. In particular, we use data from Joint Light Curve analysis (JLA) sample from Supernoave Type Ia, Baryon Acoustic… read more here.

Published in 2018 at "International Journal of Modern Physics D"

DOI: 10.1142/s021827181850058x

Abstract: We study the generalized α attractor model in the context of the late time cosmic acceleration. The model interpolates between the scaling freezing and thawing dark energy models. In the slow roll region, the original… read more here.
