A deep, multi-epoch X-ray analysis of the unobscured Seyfert 1 galaxy HE 0436-4717

Bonson, Kirsten (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 ...
Deepest serendipitous survey of the intermediate galactic latitude from XMM-Newton

Duelge, Larkin Michelle (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 ...
Exploring various corona geometries and their emissivity profiles

Gonzalez, Adam (Halifax, N.S. : Saint Mary's University, 2017)

The differences in emissivity profiles produced by various corona geometries are explored via general relativistic ray tracing simulations in order to better understand the inner disc region of active galactic nuclei. ...
Investigating X-ray variability of AGN through spectral and temporal analyses : Mrk 530 & Mrk 335

Ehler, Hannah Jae Sariah (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 ...
Strong Fe-L[alpha] fluorescent emission in type-1 Seyfert galaxies

Hurlburt, Sherry (Halifax, N.S. : Saint Mary's University, 2013)

A search for relativistically blurred Fe-L [alpha] is performed on 353 nearby broad and narrow line Type-1 active galactic nuclei (AGN). Simple phenomenological modeling is applied to establish the presence of Fe-L[alpha] ...
Using wavelet analysis to study AGN x-ray variability

Ghosh, Akshay (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 ...
Weird narrow-line seyfert 1s: A multi-epoch, broadband analysis to study the x-ray emission in mrk 1239 and wkk 4438

Buhariwalla, Margaret (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 ...
