A century of change: new changing-look event in Mrk 1018's past
Thomas Dunn, Rebecca McElroy, Mirko Krumpe +7
We investigate the long-term variability of the known Changing Look Active Galactic Nuclei (CL AGN) Mrk 1018, whose second change we discovered as part of the Close AGN Reference S…
Gravitational Torques from a Lopsided Young Stellar Component Sustain High Black Hole Accretion Rates in NGC 4593
Nico Winkel, Knud Jahnke, Juan Antonio Fernández-Ontiveros +8
Supermassive black holes (SMBHs) grow primarily through gas accretion, observed as active galactic nuclei (AGNs). While mergers can drive luminous AGN episodes, secular processes m…
The Close AGN Reference Survey (CARS): A comparison between sub-mm and optical AGN diagnostic diagrams
Jacob S. Elford, Timothy A. Davis, Ilaria Ruffa +9
The relation suggests that there is a tight connection between dense gas and star formation. We use data from the Close AGN Reference Survey (CARS) to inve…
Jet-mode feedback in NGC 5972: insights from resolved MUSE, GMRT and VLA observations
Arshi Ali, Biny Sebastian, Darshan Kakkad +10
NGC 5972, a Voorwerp galaxy, features a helical-shaped extended emission-line region (EELR) with a radius > 10 kpc and a S-shaped radio structure spanning about 470 kpc. We use VLT…
The JWST View of Cygnus A: Jet-Driven Coronal Outflow with a Twist
Patrick M. Ogle, B. Sebastian, A. Aravindan +29
We present first results from James Webb Space Telescope (JWST) Near-Infrared Spectrograph (NIRSpec), Mid-Infrared Instrument (MIRI), and Keck Cosmic Webb Imager (KCWI) integral fi…
Cocoon shock, X-ray cavities and extended Inverse Compton emission in Hercules A: clues from Chandra observations
F. Ubertosi, Y. Gong, P. Nulsen +7
We present a detailed analysis of jet activity in the radio galaxy 3C348 at the center of the galaxy cluster Hercules A. We use archival Chandra data to investigate the jet-driven…
The Close AGN Reference Survey (CARS): An interplay between radio jets and AGN radiation in the radio-quiet AGN HE 0040-1105
M. Singha, N. Winkel, S. Vaddi +14
We present a case study of HE 0040-1105, an unobscured radio-quiet AGN at a high accretion rate (Eddington ratio = 0.19+/-0.04). This particular AGN hosts an ionized gas outflow wi…
Still alive and kicking: A significant outburst in changing-look AGN Mrk 1018
R. Brogan, M. Krumpe, D. Homan +13
Changing-look active galactic nuclei (CL-AGN) have been observed to change optical spectral type. Mrk 1018 is unique: first classified as a type 1.9 Seyfert galaxy, it transitioned…
The Close AGN Reference Survey (CARS). A parsec scale multi-phase outflow in the super-Eddington NLS1 Mrk 1044
Nico Winkel, Bernd Husemann, Mainak Singha +8
The interaction between Active Galactic Nuclei (AGN) and their host galaxies is scarcely resolved. Narrow-line Seyfert 1 (NLS1) galaxies are believed to represent AGN at early stag…
The Close AGN Reference Survey (CARS): Tracing the circumnuclear star formation in the super-Eddington NLS1 Mrk 1044
N. Winkel, B. Husemann, T. A. Davis +11
The host galaxy conditions for rapid supermassive black hole growth are poorly understood. Narrow-line Seyfert 1 (NLS1) galaxies often exhibit high accretion rates and are hypothes…
The Close AGN Reference Survey (CARS): IFU survey data and the BH mass dependence of long-term AGN variability
B. Husemann, M. Singha, J. Scharwächter +19
[Abridged] AGN are thought to be intimately connected with their host galaxies through feeding and feedback processes. A spatially resolved multiwavelength survey is required to ma…
The Close AGN Reference Survey (CARS): No obvious signature of AGN feedback on star formation, but subtle trends
I. Smirnova-Pinchukova, B. Husemann, T. A. Davis +17
[Abridged] Active Galactic Nuclei (AGN) are thought to be responsible for the suppression of star formation in massive ~10 M galaxies. While this process is a key fe…
The Close AGN Reference Survey (CARS): Locating the [O III] wing component in luminous local Type 1 AGN
M. Singha, B. Husemann, T. Urrutia +13
[Abridged]The strong asymmetry in the optical [O III]5007 emission line is one of the best signatures of AGN-driven warm (~10 K) ionized gas outflows on host galaxy scales.…
Ionized Gas Outflows in Low Excitation Radio Galaxies Are Radiation Driven
Mainak Singha, Christopher P. O'Dea, Yjan A. Gordon +2
Low excitation radio galaxies (LERGs) are weakly accreting active galactic nuclei (AGN) believed to be fuelled by radiatively inefficient accretion processes. Despite this, recent…
The Close AGN Reference Survey (CARS). A massive multi-phase outflow impacting the edge-on galaxy HE1353-1917
B. Husemann, J. Scharwächter, T. A. Davis +15
[Abridged] We combine extensive spatially-resolved multi-wavelength observations, taken as part of the Close AGN Reference Survey (CARS), for the edge-on disc galaxy HE1353-1917 to…
The Close AGN Reference Survey (CARS). Discovery of a global [CII] 158 m line excess in AGN HE1353-1917
I. Smirnova-Pinchukova, B. Husemann, G. Busch +15
The [CII]158m line is one of the strongest far-infrared (FIR) lines and an important coolant in the interstellar medium of galaxies that is accessible out to high redshifts. The…
