Metallicity Gradients in Modern Cosmological Simulations II: The Role of Bursty Versus Smooth Feedback at High-Redshift
Alex M. Garcia, Paul Torrey, Aniket Bhagwat +22
The distribution of gas-phase metals within galaxies encodes the impact of stellar feedback on galactic evolution. At high-redshift, when galaxies are rapidly assembling, feedback-…
Radio-Near Infrared Imaging of Dual Active Galactic Nuclei Candidates
Makoto A. Johnstone, Ilsang Yoon, Emmanuel Momjian +13
We report the results of a pilot study that searched for dual active galactic nuclei (AGN) in local (0.25) galaxies hosting double-peaked narrow emission lines in their optical…
The Relationship Between Eddington Ratio and Column Density in U/LIRG AGN
Jaya Nagarajan-Swenson, George C. Privon, Aaron S. Evans +8
The local X-ray AGN population appears to follow a growth cycle regulated by the AGN's own radiation, marked by changes in their obscuration and Eddington ratio during accretion ev…
Searching for Compact Obscured Nuclei in Compton Thick AGN
Makoto A. Johnstone, George C. Privon, Loreto Barcos-Munoz +16
Compact Obscured Nuclei (CONs) are heavily obscured infrared cores that have been found in local (ultra)luminous infrared galaxies (U/LIRGs). They show bright emission from vibrati…
