Relativistic Jets from Compact Binary Mergers as Electromagnetic Counterparts to Gravitational Wave Sources
… astronomy, an understanding of all the potential electromagnetic counterparts to a gravitational wave detected source will help maximise the science returns. Here I present a study of the electromagnetic emission from relativistic jets that accompany the merger of binary neutron stars or black …

From Black Holes to the Big Bang: Astrophysics and Cosmology with Gravitational Waves and their Electromagnetic Counterparts
… mergers can shed light on the properties of the electromagnetic counterparts of these systems, such as short gamma-ray bursts and kilonovae. Finally, observations of the stochastic gravitational-wave background can constrain early-universe physics inaccessible with other means. In this thesis, I …

Optical Spring Stabilization
… star material, rates of black hole inspirals, electromagnetic counterparts, etc. To begin to answer all of the questions aLIGO will bring us we will need even better sensitivity in future gravitational wave detectors.</p> <p>This thesis addresses one aspect that will limit us in the future: …

A matched filter technique for slow radio transient detection and first demonstration with the Murchison Widefield Array
… compact binary coalescence, which are predicted electromagnetic counterparts of gravitational wave (GW) sources and the most promising progenitor of short gamma-ray bursts. While the next generation of GW detectors have come online and detected the first GW event, their ability to localize these …

Simulations and technology development for time-domain astronomy : TESS and InGaAs detectors
… objects out to hundreds of Mpc. Finding the electromagnetic counterparts to gravitational-wave sources, which may appear as kilonovae events, will give far greater insight into these mergers. While the Large Synoptic Survey Telescope will be a capable facility for following up triggers from …

Analytic Modelling of Gravitational-Wave Source in General Relativity and Alternative Theories of Gravity
… using the information of the observation of electromagnetic counterparts of the GW signal GW170817 and improved fits of the threshold mass. The application of the improved fits to the GW170817 signal implies that a significant part of the parameter space is not supported by the observation of …

On the parallels between the Maxwell and Dirac equations
… these electronic fields closely parallel their electromagnetic counterparts. We also make a discussion on wave components we may measure if the matter wave is actually measurable. Likewise, we reformulate Maxwell’s equations into an \emph{exact} form of the Dirac equation, which we term the …

Frequency chirping of energetic particle driven modes in tokamaks; Self-consistent modelling and simulation
… of chirping waves as a 1D paradigm of their electromagnetic counterparts. In order to build more realistic models, nonperturbative theory needs to be extended to electromagnetic waves and also fast particle orbital dynamics should be captured. In this work, a model is developed to investigate …

Novel aspects of the dynamics of binary black-hole mergers
… to analytical tools. We study electro-magnetic counterparts of super-massive binary black-hole mergers with fully 3D general relativistic simulations of binary black-holes immersed both in a uniform magnetic field in vacuum and in a tenuous plasma. We find that while a direct detection of merger …
