A 3-D radiative transfer analysis of AGB winds
(NUI Galway, 2024-04-16)The chemical enrichment of the interstellar medium is driven by stars of low to intermediate masses shedding their external layers through powerful stellar winds. Eventually, after many years in this phase, the core of ... -
Aerosols and the imaging atmospheric Cherenkov technique
(2018-02-22)The ability to extract energetic γ-rays from the overwhelming high energy cosmic ray back- ground has opened up a new window of observation on the non-thermal universe. By utilis- ing an atmospheric technique VERITAS, an ... -
Decoding the kinematic and ionisation structure of axisymmetric nebulae
(NUI Galway, 2021-08-04)The aim of the thesis was to develop a code and pipeline for generating 3D photoionisation models of axisymmetric nebulae to better understand their ob- served structure and composition. This was achieved through a new ... -
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 ... -

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 ... -
Radiative transfer of star formation and destruction regions
(NUI Galway, 2022-12-14)While star formation and destruction may lie at the opposite ends of a star's life cycle, they display remarkable similarities. Both star forming regions and pre-planetary nebulae can be detected by observing molecular ... -
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 ...
