Gemini North Adaptive Optics (GNAO) facility overview and status updates
Gaetano Sivo, Julia Scharwächter, Manuel Lazo +54
The Gemini North Adaptive Optics (GNAO) facility is the upcoming AO facility for Gemini North providing a state-of-the-art AO system for surveys and time domain science in the era…
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…
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…
Dissecting Galaxies: Spatial and Spectral Separation of Emission Excited by Star Formation and AGN Activity
Rebecca L. Davies, Brent Groves, Lisa J. Kewley +13
The optical spectra of Seyfert galaxies are often dominated by emission lines excited by both star formation and AGN activity. Standard calibrations (such as for the star formation…
Large-scale outflows in luminous QSOs revisited: The impact of beam smearing on AGN feedback efficiencies
B. Husemann, J. Scharwächter, V. N. Bennert +3
[Abridged] Enormous observational efforts have been made to constrain the energetics of AGN feedback by mapping the kinematics of the ionized gas on kpc scale. We study how the obs…
