A multiwavelength investigation of blazar-type active galactic nuclei.
(University of Canterbury. Department of Physics and Astronomy, 2013)
A multiwavelength investigation is conducted for nineteen blazar-type active galactic nuclei. Studies of variability timescales and flux duty cycles are performed at x- and gamma-rays for each source, with the relationship ...
Small animal irradiation using the MARS Spectral CT
(University of Canterbury. Physics and Astronomy, 2013)
This thesis reports on a novel use of the Medipix All Resolution System (MARS) Spectral CT scanner as a platform of small animal irradiation. Irradiation from the x-ray source in the scanner was used to inhibit the growth ...
Clinical applications of the Medipix detector
(University of Canterbury. Physics and astronomy, 2012)
In this thesis a recently developed energy resolving x-ray detector (Medipix) is used to investigate potential medical applications of spectral x-ray imaging. Computed Tomography (CT) is one of the most important medical ...
