Probing Heavily Obscured AGN in Major Galaxy Mergers Using the mm-X-ray Correlation
M. Droguett-Callejas, E. Treister, L. Barcos-Muñoz +10
The study of heavily obscured supermassive black hole (SMBH) growth in late-stage galaxy mergers is challenging: column densities can bloc…
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…
Molecular Gas in Major Mergers Hosting Dual and Single AGN at <10 kpc Nuclear Separations
Makoto A. Johnstone, Ezequiel Treister, Franz E. Bauer +24
We present high-resolution (50100 pc) Atacama Large Millimeter Array (ALMA) observations of CO(2-1) or CO(1-0) emission in seven local ( 0.05)…
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…
The Arp 240 Galaxy Merger: A Detailed Look at the Molecular Kennicutt-Schmidt Star Formation Law on Sub-kpc Scales
Alejandro Saravia, Eduardo Rodas-Quito, Loreto Barcos-Muñoz +25
The molecular Kennicutt-Schmidt (mK-S) Law has been key for understanding star formation (SF) in galaxies across all redshifts. However, recent sub-kpc observations of nearby galax…
