(Halifax, N.S. : Saint Mary's University, 2017)The field of high-energy AGN astrophysics is about to be transformed as data of unprecedented quality and quantity will be arriving from the next-generation of X-ray observatories. With the advancement of technology, we ...

(Halifax, N.S. : Saint Mary's University, 2013)This work presents a deep analysis of HE 0436-4717: a “bare” Seyfert 1 galaxy with strong variability and moderate soft excess. Data included a 200 ks observation with XMM-Newton EPIC instruments, a Swift BAT detection up ...

(Halifax, N.S. : Saint Mary's University, 2011)The XMM-Newton Observatory has conducted many observations of the type I active galactic nucleus 1H0707-495. The 0.7 deg [superscript 2] field of view around the AGN was observed over the course of ∼10 years with a total ...

(Halifax, N.S. : Saint Mary's University, 2019)X-ray observations of two Seyfert AGN were analysed in an effort to characterise the nature of their variability. A spectral analysis was performed on a Suzaku observation of the Seyfert 1.5 AGN Mrk 530, and a timing ...

(Halifax, N.S. : Saint Mary's University, 2021)High-velocity outflows in active galactic nuclei usually manifest as either a collimated jet or diffuse wind. These outflows carry a significant amount of energy from the central environment surrounding the supermassive ...

(Halifax, N.S. : Saint Mary's University, 2023-08-01)In this work, we examine the application of the wavelet transform to the X-ray timing analyses of active galactic nuclei (AGN) and quasi-periodic eruption sources (QPEs). We find that the power spectral density (PSD) slope ...

(Halifax, N.S. : Saint Mary's University, 2021)X-ray emission from Seyfert 1 galaxies has a debated origin. The primary X-ray source is the compact corona, but the secondary X-ray emission is thought to originate from either a Comptonising layer or blurred reflection ...
