Holographic hydrodynamics: models and methods

Nabamita Banerjee, Suvankar Dutta

We review recent developments in holographic hydrodynamics. We start from very basic discussion on hydrodynamic systems and motivate why string theory is an essential tool to deal…

Analysis of WMAP 7-year Temperature Data: Astrophysics of the Galactic Haze

Davide Pietrobon, Krzysztof M. Gorski, James Bartlett +10

We analyse WMAP 7-year temperature data, jointly modeling the cosmic microwave background (CMB) and Galactic foreground emission. We use the Commander code based on Gibbs sampling.…

Cosmology of Horava-Lifshitz f(R) Gravity

Sayan K. Chakrabarti, Koushik Dutta, Anjan A. Sen

We discuss the cosmology of recently proposed Horava-Lifshitz f(R) gravity. In particular, we derive the modified Hubble equation that reduces to the standard HL gravity case in ap…

Testing Unimodular Gravity

Pankaj Jain, Purnendu Karmakar, Subhadip Mitra +2

We consider models of gravitation that are based on unimodular general coordinate transformations (GCT). These transformations include only those which do not change the determinan…

Quantum Treatment of the Weyl Vector Meson

Naveen K. Singh, Pankaj Jain, Subhadip Mitra +1

The Weyl meson arises in theories with local scale invariance. It acts as a candidate for dark matter in a generalized Standard Model with local scale invariance. The Higgs particl…

A Foreground Cleaned CMB Map from Non-Gaussianity Measurement

Rajib Saha

In this paper we present a new method to estimate a foreground cleaned Cosmic Microwave Background (CMB) map at a resolution of $1^{\circ}$ by minimizing the non-Gaussian properties…

Analysis of the lepton polarisation asymmetries of $B ˉ \to K ˉ_{2} (1430) ℓ^{+} ℓ^{-}$ decay

S. R. Choudhury, A. S. Cornell, J. D. Roussos

In this work we will study the longitudinal polarisations of both leptons in the decay process $B ˉ \to K ˉ_{2} (1430) ℓ^{+} ℓ^{-}$ . This process has all the features…

Cosmological Perturbation Analysis in a Scale Invariant Model of Gravity

Pankaj Jain, Purnendu Karmakar, Subhadip Mitra +2

We consider a model for gravity that is invariant under global scale transformations. It includes one extra real scalar field coupled non-minimally to the gravity fields. In this m…

Roots of Dehn twists about separating curves

Kashyap Rajeevsarathy

Let $C$ be a curve in a closed orientable surface $F$ of genus $g \geq 2$ that separates $F$ into subsurfaces $F_{i}$ of genera $g_{i}$ , for $i = 1, 2$ . We study the set of…
