The Hunt for Red Dual AGNs I: Spatially-Resolved Mid-IR Dual AGNs in the DeCam Legacy Survey

Ryan W. Pfeifle, Kimberly A. Weaver, Barry Rothberg +13

Theoretical studies predict that dual AGNs are a critical stage of galaxy merger-driven supermassive black hole growth. Systematic searches for dual AGNs typically target late-stag…

AGN versus Star-formation: A MUSE Analysis of NGC 1365

Kyla Mullaney, Kelly E. Whalen, Jenna Cann +3

Active galactic nuclei (AGN) and star formation feedback may heat and remove gas from galaxies in a process that quenches ongoing star formation and shapes the evolution of galaxie…

Limitations on Morphological Fitting for JWST "Little Red Dots"

Kelly E. Whalen, Kimberly A. Weaver, Ryan C. Hickox +1

Early results from JWST uncover a peculiar class of objects referred to as ``little red dots'' (LRDs). The extremely compact morphology of LRDs is often invoked to point towards an…

Super-Size Me: The Big Multi-AGN Catalog (The Big MAC), Data Release 1: The Source Catalog

Ryan W. Pfeifle, Kimberly A. Weaver, Nathan J. Secrest +2

Galaxy mergers represent the most transformative and dramatic avenue for galaxy and supermassive black hole (SMBH) evolution. Multi-active galactic nuclei (multi-AGNs) are expected…

Kpc-Scale Neutral Iron K Emission in the Starburst-AGN NGC 4945: a Relic AGN Outflow?

Kimberly A. Weaver, Jenna M. Cann, Lynne Valencic +8

NGC 4945 contains a well-known heavily obscured active galactic nucleus (AGN) at its core, with prior reports of strong nuclear and off-nuclear neutral Fe K emission due to the…
