Multiband Modelling and Radio Observations of Gamma Ray Burst Afterglows
The widely popular and successful standard fireball model for Gamma Ray Burst (GRB) afterglows is based on ultra-relativistic external shocks sweeping up matter around the explosion site to accelerate electrons up to GOV ...
3D Dosimetry using optical tomography and electronic portal images
The primary goal of this thesis is to develop techniques to quantify the radiation
dose distributions used in radiotherapy for cancer treatment. It aims at developing
a physically profound calculation model for the transit ...
Study on optical and electrical transport properties of twisted bilayer transition metal dichalcogenides
Van der Waals (vdW) heterostructures, where dissimilar atomically thin vdW crystals are vertically assembled, have initiated a new paradigm to create flexible multifunctional devices. Despite the weak nature of vdW ...
Quantized heat flow probing thermal equilibration and edge structures of quantum Hall phases in graphene
In condensed matter physics, usually, phases are described using Landau’s approach, which characterizes the phases in terms of underlying symmetries that are spontaneously broken. Over the past few decades, a different ...
Mechanical Properties of Nucleic Acids in Bulk and Under Confinement and Their Interaction with Peptide
Proteins, DNA and RNA are arguably the most studied biological molecules with curiously interconnected relation that appears ubiquitous in all organisms. Almost all nucleoprotein interactions and DNA manipulation events ...
Effect of As and Se substitution on the Phase Change properties of GeTe based alloys
Phase-change memory (PCM) is a key enabling technology for non-volatile electrical data storage at the nanometer scale. A PCM device consists of a small active volume of phase-change material between two electrodes. In ...
On the Nature Of Propagating MHD Waves In The Solar Atmosphere
(2014-10-15)
One of the most persistent problem in solar physics is the identification of the mechanism that heats the solar corona and accelerates the fast solar wind. Magneto-hydrodynamic (MHD)waves play a crucial role in heating of ...
A Radio Study Of Gas Loss Processes In Nearby Galaxies
(2008-10-17)
The work in this thesis involves detailed multi-frequency radio continuum
(from 325 MHz to 15 GHz) and Hi spectroscopic studies of a few represent
tative nearby galaxies which are experiencing gas-loss from their disks ...
Observational Aspects Of Core Collapse Supernovae
(2013-10-17)
The discovery of several bright supernovae (SNe) in recent years has evoked a great deal of interest in these objects. The study of these objects are of importance not only as probes to the end stages of stellar evolution, ...
