(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 ...

Missing stellar mass in SED fitting: spatially unresolved photometry can underestimate galaxy masses (Oxford University PressRoyal Astronomical Society, 2015)We fit model spectral energy distributions (SEDs) to each pixel in 67 nearby (= 0.0057) galaxies using broad-band photometry from the Sloan Digital Sky Survey and GALEX. For each galaxy, we compare the stellar mass ...

(American Astronomical SocietyIOP Publishing, 2002-03-10)We report the results of experiments aimed at reducing the major problem with cooling flow models of rich cluster X-ray sources, i.e., the fact that most of the cooled gas or its products have not been found. Here we show ...

(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, 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] ...

(American Astronomical Society, 2008-07)We report the discovery of strong soft X-ray emission lines and a hard continuum above 2 keV in the narrow-line Seyfert 1 galaxy Mrk 335 during an extremely low X-ray flux state. Mrk 335 was observed for 22 ks by XMM-Newton ...
