A Population of Little Red Dot-like Quasars in SDSS
Quinn O. Casey, Ryan C. Hickox, Nikko J. Cleri +6
Compact and red sources in the high redshift () Universe, known as "Little Red Dots" (LRDs), are among JWST's most intriguing discoveries. These sources have broad Balmer e…
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…
The case for super-Eddington accretion in JWST broad-line AGN during the first billion years
Erini Lambrides, Rebecca Larson, Kristen Garofali +23
A multitude of JWST studies reveal a surprising over-abundance of over-massive accreting super-massive black holes (SMBHs) -- leading to a deepening tension between theory and obse…
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…
The Need for Ultra High Resolution X-ray Imaging
Kimberly A. Weaver, Jenna M. Cann, Ryan Pfeifle +20
This paper discusses the broad science case for obtaining milliarcsecond to microarcsecond astronomical imaging resolution in the soft to medium-energy X-ray band (~0.5 to ~8 keV).…
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…
