(Halifax, N.S. : Saint Mary's University, 2016)The halo nucleus [superscript 11]Li was explored through elastic and inelastic scattering off protons at the TRIUMF facility in Vancouver using the IRIS facility. IRIS pioneers in using thin windowless solid hydrogen target ...
-
(Halifax, N.S. : Saint Mary's University, 2024-04-22)NGC 6814, a Seyfert 1.5 Active Galactic Nucleus (AGN) at redshift z = 0.00522, is a compelling object to study due to its high X-ray variability and the presence of photoionized gas outflows. In 2016, a rapid occultation ...
-
(Halifax, N.S. : Saint Mary's University, 2023-04-17)The X-ray spectra of active galactic nuclei (AGN) contain many spectral features, such as emission lines, that provide much insight into the inner workings of these objects. In a class of AGN known as Narrow-Line Seyfert ...
-
(Halifax, N.S. : Saint Mary's University, 2013)The ISAC Charged Particle Spectroscopy Station (IRIS) at TRIUMF, Vancouver, Canada uses CsI(Tl)—a 16 component detector array composed of thallium-doped cesium iodide—for high resolution study of nuclear reactions. Each ...
-
(Halifax, N.S. : Saint Mary's University, 2014)The formation of plume structures has long been a consequence of fluid modelling of extragalactic radio jets. Simulations performed to date, which have been executed with and without reflective boundary conditions along ...
-
(Halifax, N.S. : Saint Mary's University, 2020)This thesis documents the development of an Event Display for use in the BigBite calorimeter in the Super BigBite (SBS) ecosystem of detectors in Jefferson Lab’s Hall A. The development of a functional Event Display also ...
-
(Halifax, N.S. : Saint Mary's University, 2013)Structure is found in the Universe on various scales ranging from galaxies to galaxy clusters, super clusters. . .This structure is believed to have formed in a bottom-up hierarchical way. Computational techniques allow ...
-
(Halifax, N.S. : Saint Mary's University, 2022-05-11)Current, state-of-the-art equilibrium mass models of globular clusters assume that all stars are single, making the effects of binary systems an unknown quantity. In this thesis we develop a method to include realistic ...
-
(Halifax, N.S. : Saint Mary's University, 2024-04-19)Using the simulation code GIZMO, two different configurations of dark matter and gas were collided at three different resolutions in order to study the energy transfer between the dark matter and gas. The first configuration ...
-
(Halifax, N.S. : Saint Mary's University, 2013)Epsilon Aurigae is a third magnitude, long-period binary that eclipses every 27.1 years and has been continuously observed for more than 160 years. The observed spectrum is that of an apparently normal F supergiant. The ...
-
(Halifax, N.S. : Saint Mary's University, 2013)Neutron-rich unstable isotopes are critical to our understanding of the origins of the heavy elements found on Earth. Their properties, such as mass and binding energy, enable us to look into the nuclear structure, and ...
-
(Halifax, N.S. : Saint Mary's University, 2017)Markarian 335, a Narrow-Line Seyfert 1 Galaxy, has been one the brightest X-ray sources in the sky until 2007 when its flux dropped to 1/10th of its previous value. Despite this dramatic decrease, Mrk 335 still remains one ...
-
(Halifax, N.S. : Saint Mary's University, 2019)ChromaStarPy is a stellar atmosphere and spectrum modeling code written in python designed to give good approximations of stellar spectra, whilst being easily accessible to students at a wide range of levels. We present ...
-
(Halifax, N.S. : Saint Mary's University, 2023-04-22)The dense environment in the cores of globular clusters enables three-body interactions involving a binary system and a single star to occur frequently, which can eject high-velocity stars from the cluster. The velocities ...
-
(Halifax, N.S. : Saint Mary's University, 2015)The Super BigBite Spectrometer project in Hall A of the Thomas Jefferson National Accelerator Facility (JLab) is finalizing the design of a required radiation detector called the Coordinate Detector (CDet) for use in ...
-
(Halifax, N.S. : Saint Mary's University, 2016)A nuclear halo is a nucleus which has a large extended surface region of either one or two pro-tons or neutrons surrounding a compact core nucleus. A Borromean nucleus is a special case consisting of a core surrounded by ...
-
Investigating the excitation spectrum of [superscript 8]He from inelastic scattering with deuterons (Halifax, N.S. : Saint Mary's University, 2022-04-26)Rare isotopes are nuclei with very short half-lives and can have a large asymmetry of neutrons to protons. These isotopes can have unusual structures such as halos that can exhibit a phenomenon known as a Soft Dipole ...
-
(Halifax, N.S. : Saint Mary's University, 2021)The behavior of neutron and proton rich nuclei that lie far from the region of stability is a matter of great scientific interest. This is because not only do these nuclei play important roles in stellar nucleosynthesis ...
-
(Halifax, N.S. : Saint Mary's University, 2023-04-05)This study aims to investigate the heavy-ion particle identification in an experiment designed to determine the astrophysical rate of the 15O(α,γ)19Ne reaction.
The 15O(&a ...
-
(Halifax, N.S. : Saint Mary's University, 2016)The ISAC charged particle reaction spectroscopy station (IRIS), is an experimental facility stationed at TRIUMF Vancouver. IRIS was developed to study direct reactions with rare isotope beams. It is a tremendous challenge ...
