Rapid growth in a dual AGN during a gas-rich merger at z~4.5
Hyewon Suh, Roberto Decarli, Emanuele Paolo Farina +15
The late stages of galaxy mergers - when two supermassive black holes (SMBHs) reach kiloparsec-scale separations - represent a critical phase for understanding SMBH growth, galaxy…
The Central Kinematics and Black Hole Mass of 4C+37.11
Tirth Surti, Roger W. Romani, Julia Scharwächter +2
We report on IFU measurements of the host of the radio source 4C+37.11. This massive elliptical contains the only resolved double compact nucleus at pc-scale separation, likely a b…
Jet-driven galaxy-scale gas outflows in the hyper-luminous quasar 3C273
B. Husemann, V. N. Bennert, K. Jahnke +6
We present an unprecedented view on the morphology and kinematics of the extended narrow-line region (ENLR) and molecular gas around the prototypical hyper-luminous quasar 3C273 ($…
The Close AGN Reference Survey (CARS): Mrk 1018 halts dimming and experiences strong short-term variability
M. Krumpe, B. Husemann, G. R. Tremblay +12
After changing optical AGN type from 1.9 to 1 in 1984, the AGN Mrk 1018 recently reverted back to its type 1.9 state. Our ongoing monitoring now reveals that the AGN has halted its…
The Close AGN Reference Survey (CARS) - What is causing Mrk1018's return to the shadows after 30 years?
B. Husemann, T. Urrutia, G. R. Tremblay +11
We recently discovered that the active galactic nucleus (AGN) of Mrk 1018 has changed optical type again after 30 years as a type 1 AGN. Here we combine Chandra, NuStar, Swift, Hub…
The Close AGN Reference Survey (CARS) - Mrk 1018 returns to the shadows after 30 years as a Seyfert 1
R. E. McElroy, B. Husemann, S. M. Croom +10
We report the discovery that the known `changing look' AGN Mrk 1018 has changed spectral type for a second time. New VLT-MUSE data taken in 2015 as part of the Close AGN Reference…
