The PHANGS-Hα survey. Ground-based narrow-band imaging of nearby star-forming galaxies
Alessandro Razza, Guillermo A. Blanc, Brent Groves +36
We present PHANGS-Hα, a narrow-band imaging survey that maps Hα emission over a sample of 65 nearby massive star-forming galaxies. The data were obtained using the MPG-ESO 2.2-mete…
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…
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…
The Close AGN Reference Survey (CARS). Long-term spectral variability study of the changing look AGN Mrk 1018
T. Saha, M. Krumpe, A. Markowitz +9
Changing-look AGNs (CLAGN) are accreting supermassive black hole systems that undergo variations in optical spectral type, driven by major changes in accretion rate. Mrk 1018 has u…
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…
