FRAMEx IV: Mechanical Feedback from the Active Galactic Nucleus in NGC 3079

Autor: Fernandez, Luis C., Secrest, Nathan J., Johnson, Megan C., Fischer, Travis C.

Using the Very Long Baseline Array, we observed the active galactic nucleus (AGN) in NGC 3079 over a span of six months to test for variability in the two main parsec-scale radio components, $A$ and $B$, which lie on either side of the AGN. We found

Fundamental Reference AGN Monitoring Experiment (FRAMEx) III: Radio Emission in the Immediate Vicinity of Radio Quiet AGNs

Autor: Shuvo, Onic I., Johnson, Megan C., Secrest, Nathan J., Gliozzi, Mario, Fischer, Travis C., Cigan, Phillip J., Fernandez, Luis C., Dorland, Bryan N.

We present follow-up results from the first Fundamental Reference AGN Monitoring Experiment (FRAMEx) X-ray/radio snapshot program of a volume-complete sample of local hard X-ray-selected active galactic nuclei (AGNs). Here, we added 9 new sources to

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

Autor: Fernandez, Luis C., Secrest, Nathan J., Johnson, Megan C., Schmitt, Henrique R., Fischer, Travis C., Cigan, Phillip J., Dorland, Bryan N.

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 observing campaign, we observed a large drop in core 5 cm radio luminosity,

Fundamental Reference AGN Monitoring Experiment (FRAMEx) I: Jumping Out of the Plane with the VLBA

Autor: Fischer, Travis C., Secrest, Nathan J., Johnson, Megan C., Dorland, Bryan N., Cigan, Phillip J., Fernandez, Luis C., Hunt, Lucas R., Koss, Michael, Schmitt, Henrique R., Zacharias, Norbert

We present the first results from the Fundamental Reference AGN Monitoring Experiment (FRAMEx), an observational campaign dedicated to understanding the physical processes that affect the apparent positions and morphologies of AGNs. In this work, we
