Gas condensation in Brightest Group Galaxies unveiled with MUSE
V. Olivares, P. Salome, S. L. Hamer +18
The origin of the cold gas in central galaxies in groups is still a matter of debate. We present Multi-Unit Spectroscopic Explorer (MUSE) observations of 18 optically selected loca…
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…
Ubiquitous cold and massive filaments in cool core clusters
V. Olivares, P. Salomé, F. Combes +20
Multi-phase filamentary structures around Brightest Cluster Galaxies are likely a key step of AGN-feedback. We observed molecular gas in 3 cool cluster cores: Centaurus, Abell S110…
Weak Lensing analysis of Abell 2390 using short exposures
A. Dutta, J. R. Peterson, T. Rose +4
We present a weak lensing analysis of the galaxy cluster Abell 2390 at z = 0.23 using second moment shape measurements made in 411 short 60s exposures. The exposures are obtained i…
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.…
Gas Motions in Hydra-A: XRISM Constraints on ICM Kinematics Across Jet-Inflated Cavities
Anwesh Majumder, B. R. McNamara, P. E. J. Nulsen +8
We report on two deep XRISM observations of the central and northern regions of Hydra-A's X-ray atmosphere covering the bubbles inflated by jets from the central galaxy's active ga…
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…
