Uncovering New Ionized Winds and Relativistic Hot Outflows in MCG-6-30-15 with \emph{Chandra} HETG and a Bayesian Framework

Erika B. Hoffman, Anna Ogorzałek, Christopher S. Reynolds +1

Active Galactic Nuclei (AGN) feedback plays a key role in galaxy evolution. Highly ionized outflows, detected in X-ray absorption, are a promising candidate for quasar-mode feedbac…

A new 2D stochastic methodology for simulating variable accretion discs: propagating fluctuations and epicyclic motion

Samuel G. D. Turner, Christopher S. Reynolds

Accretion occurs across a large range of scales and physical regimes. Despite this diversity in the physics, the observed properties show remarkably similarity. The theory of propa…

An XMM-Newton Study of Six Narrow-Line Seyfert 1 Galaxies at z = 0.35--0.92

Zhibo Yu, Jiachen Jiang, Cosimo Bambi +5

We report a detailed analysis of the XMM-Newton spectra of six Narrow-Line Seyfert 1 (NLS1) galaxies at redshift z = 0.35--0.92. Compared with the NLS1s at lower redshift in the pr…

Current and Future constraints on Very-Light Axion-Like Particles from X-ray observations of cluster-hosted Active Galaxies

Julia M. Sisk-Reynes, Christopher S. Reynolds, James H. Matthews

We discuss our recent constraints on the coupling of Very-Light Axion-Like Particles (of masses ) to electromagnetism from observations of the…

UV/Optical disk reverberation lags despite a faint X-ray corona in the AGN Mrk 335

Erin Kara, Aaron J. Barth, Edward M. Cackett +37

We present the first results from a 100-day Swift, NICER and ground-based X-ray/UV/optical reverberation mapping campaign of the Narrow-Line Seyfert 1 Mrk 335, when it was in an un…

Line Driven Winds from Variable Accretion Discs

Anthony Kirilov, Sergei Dyda, Christopher S. Reynolds

We use numerical hydrodynamics simulations to study line driven winds launched from an accreting alpha-disc. Building on previous work where the driving radiation field is static,…
