VaDAR: Varstrometry for Dual AGN using Radio interferometry

Emma Schwartzman, Tracy E. Clarke, Kristina Nyland +5

Binary and dual active galactic nuclei (AGN) are an important observational tool for studying the formation and dynamical evolution of galaxies and supermassive black holes (SMBHs)…

Investigating the Narrow Line Region Dynamics in Nearby Active Galaxies

Beena Meena, D. Michael Crenshaw, Henrique R. Schmitt +7

We present dynamical models of the narrow line region (NLR) outflows in the nearby Seyfert galaxies Mrk 3, Mrk 78, NGC 1068, and NGC 4151 using observations from the Hubble Space T…

Quantifying Feedback from Narrow Line Region Outflows in Nearby Active Galaxies. IV. The Effects of Different Density Estimates on the Ionized Gas Masses and Outflow Rates

Mitchell Revalski, D. Michael Crenshaw, Marc Rafelski +9

Active galactic nuclei (AGN) can launch outflows of ionized gas that may influence galaxy evolution, and quantifying their full impact requires spatially resolved measurements of t…

FRAMEx II: Simultaneous X-ray and Radio Variability in Active Galactic Nuclei The Case of NGC 2992

Luis C. Fernandez, Nathan J. Secrest, Megan C. Johnson +4

Using simultaneous Very Long Baseline Array and Neil Gehrels Swift Observatory X-ray Telescope observations of the active galactic nucleus (AGN) in NGC 2992 over a six-month observ…

Tracking X-ray Outflows with Optical/IR Footprint Lines

Anna Trindade Falcao, S. B. Kraemer, D. M. Crenshaw +5

We use Cloudy photoionisation models to predict the flux profiles for optical/IR emission lines that trace the footprint of X-ray gas, such as [Fe X] 6375A and [Si X] 1.43m. The…

Hubble Space Telescope [O III] Emission-Line Kinematics in Two Nearby QSO2s: A Case for X-ray Feedback

Anna Trindade Falcão, S. B. Kraemer, T. C. Fischer +15

We present a dynamical study of the narrow-line regions in two nearby QSO2s. We construct dynamical models based on detailed photoionization models of the emission-line gas, includ…
