Investigating the Periodic X-ray Behaviour in the Eclipsing AGN NGC 6814
T. O. Hodd, L. C. Gallo, A. G. Gonzalez +2
The paper analyzes a ~45‑50 µHz periodic X‑ray signal observed before an eclipse in the Seyfert galaxy NGC 6814, using timing and spectral methods to explore its origin, suggesting…

On the Fe xxii Emission in the X-ray spectrum of NGC 1068
M. Z. Buhariwalla, J. M. Miller, L. C. Gallo +3
The Fe xxii doublet has been previously used to determine the density of collisionally ionized emission from magnetic cataclysmic variable stars. We test how this diagnostic double…

A Spectral Energy Distribution Variability Study of the Eclipsing AGN NGC 6814
L. K. Pothier-Bogoslowski, L. C. Gallo, A. G. Gonzalez +2
The local Seyfert 1.5 active galactic nucleus (AGN), NGC 6814, is known to exhibit complex variability, eclipses, and even changing-look behaviour. In this work, we utilize optical…
