Polarisation of synchrotron radiation from isolated neutron stars
(2016-03-10)
Pulsars are enigmatic neutron stars which have defied efforts to understand them for over 40 years. POREC (Pulsar Optical Reverse Engineering Code) was first written to constrain pulsar emission theories through constraining ...
Star formation in extreme environments
(2015-12-22)
The study of star formation bridges many vastly disparate scales. From the small, nearby, quiescent cores of low mass star formation, to the highly turbulent conditions in which the most massive stars form, to the extreme ...
Development of a high time resolution optical polarimeter for astronomy
(NUI Galway, 2018-12-17)
This work started in September, 2014 and initially started as an investigation of
the characterisation issues associated with using Electron Multiplying Charge-
Coupled Devices (EMCCDs) in a two beam polarimeter. It was ...
Planet engulfment and the planetary nebula morphology mystery
(NUI Galway, 2018-04-13)
This thesis presents an investigation into the galactic population of planetary nebulae (PNe) whose progenitors have evolved through the engulfment of massive planets during the asymptotic giant branch (AGB) phase of their ...
A morpho-kinematic and spectroscopic study of bipolar planetary nebulae
(2015-09-28)
In this thesis, studies of the kinematic properties for a sample of Galactic bipolar planetary nebulae, based on optical and infrared observations, were performed us- ing a morpho–kinematic code, optical and NIR diagnostic ...
Structure and evolution of classical Nova Shells
(2017-09-22)
This thesis focuses on shells ejected during classical nova events. Novae are due to thermonuclear runaway on the surface of a white dwarf in a binary system. The work herein concentrates on nova shells individually to ...
IMPAIR: Massively parallel regularised Richardson-Lucy deconvolution on heterogeneous hardware
(2017-10-27)
This thesis investigates the comparative performance of multicore CPU and general purpose GPU on a commodity desktop computer. To investigate this, an image deconvolution software package (IMPAIR) was updated from its ...
A study of turbulence and infall over multiple scales of star formation
(2014-09-28)
The understanding of the processes of star formation informs the understanding and investigation of questions of galactic dynamics and the formation of stellar systems of exoplanets and so sits between the galactic and ...
Multi-wavelength and Polarisation Studies of Pulsars: the Crab, Vela, and PSR J0205+6449
(2014-12-11)
This thesis outlines the findings of a multi-wavelength and polarimetric study of
a number of rotation-powered pulsars. Polarisation studies of pulsars are just one
example of obtaining insight into the geometry of their ...
Development and Implementation of an Ultra High Speed Astronomical Polarimeter: The Galway Astronomical Stokes Polarimeter (GASP)
(2013-05-12)
Optical polarization is a powerful diagnostic tool in astrophysics, allowing the
investigation of asymmetries in source regions of astronomical objects, magnetic
field configurations, and magnetic field strengths. Polarized ...
