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…
Correlations between Supermassive Black Holes and their Hosts in Active Galaxies
Gerold Busch
In the last decades several correlations between the mass of the central supermassive black hole (BH) and properties of the host galaxy - such as bulge luminosity and mass, central…
Star formation and gas flows in the centre of the NUGA galaxy NGC 1808 observed with SINFONI
Gerold Busch, Andreas Eckart, Mónica Valencia-S. +4
NGC 1808 is a nearby barred spiral galaxy which hosts young stellar clusters in a patchy circumnuclear ring with a radius of . In order to study the gaseous…
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…
A low-luminosity type-1 QSO sample: II. Tracing circumnuclear star formation in HE 1029-1831 with SINFONI
Gerold Busch, Semir Smajić, Julia Scharwächter +6
Circumnuclear star formation and AGN feedback is believed to play a critical role in the context of galaxy evolution. The low-luminosity QSO (LLQSO) sample that contains 99 of the…
