The NuSTAR, XMM-Newton, and Suzaku view of A3395 at the intercluster filament interface
Aysegul Tumer, Daniel R. Wik, Massimo Gaspari +4
Galaxy clusters are the largest virialized objects in the universe. Their merger dynamics and their interactions with the cosmic filaments that connect them are important for our u…
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.…
The deepest view of RBS 797: evidence for two pairs of equidistant X-ray cavities
Francesco Ubertosi, Myriam Gitti, Fabrizio Brighenti +14
We present the first results of a deep observation of the galaxy cluster RBS 797, whose previous X-ray studies revealed two pronounced X-ray cavities in the east-west (E-…
Multi-scale feedback and feeding in the closest radio galaxy Centaurus A
B. McKinley, S. J. Tingay, M. Gaspari +12
Supermassive black holes and supernovae explosions at the centres of active galaxies power cycles of outflowing and inflowing gas that affect galactic evolution and the overall str…
AGN feeding and feedback in Fornax A: kinematical analysis of the multi-phase ISM
F. M. Maccagni, P. Serra, M. Gaspari +10
We present a multi-wavelength study of the gaseous medium surrounding the nearby active galactic nucleus (AGN) Fornax A. Using MeerKAT, ALMA and MUSE observations we reveal a compl…
Multiphase Powerful Outflows Detected in High-z Quasars
George Chartas, Massimo Cappi, Cristian Vignali +7
We present results from a comprehensive study of ultrafast outflows (UFOs) detected in a sample of fourteen quasars, twelve of which are gravitationally lensed, in a redshift range…
Feedback from Active Galactic Nuclei in Galaxy Groups
Dominique Eckert, Massimo Gaspari, Fabio Gastaldello +2
The co-evolution between supermassive black holes and their environment is most directly traced by the hot atmospheres of dark matter halos. Cooling of the hot atmosphere supplies…
The metal content of the hot atmospheres of galaxy groups
Fabio Gastaldello, Aurora Simionescu, Francois Mernier +4
Galaxy groups host the majority of matter and more than half of all the galaxies in the Universe. Their hot ( K), X-ray emitting intra-group medium (IGrM) reveals emission li…
Scaling Properties of Galaxy Groups
Lorenzo Lovisari, Stefano Ettori, Massimo Gaspari +1
Galaxy groups and poor clusters are more common than rich clusters, and host the largest fraction of matter content in the Universe. Hence, their studies are key to understand the…
Radio galaxies in galaxy groups: kinematics, scaling relations and AGN feedback
T. Pasini, A. Finoguenov, M. Brüggen +3
We investigate the kinematic properties of a large (N=998) sample of COSMOS spectroscopic galaxy members distributed among 79 groups. We identify the Brightest Group Galaxies (BGGs…
An H/X-ray orphan cloud as a signpost of the intracluster medium clumping
Chong Ge, Rongxin Luo, Ming Sun +12
Recent studies have highlighted the potential significance of intracluster medium (ICM) clumping and its important implications for cluster cosmology and baryon physics. Many of th…
WISDOM project -- VIII. Multi-scale feedback cycles in the brightest cluster galaxy NGC 0708
Eve V. North, Timothy A. Davis, Martin Bureau +8
We present high-resolution (synthesised beam size 0."088x0."083 or 25x23 pc) Atacama Large Millimetre/submillimetre Array (ALMA) CO(2-1) line and 236 GHz continuum obser…
The Clusters Hiding in Plain Sight (CHiPS) survey: CHIPS1911+4455, a Rapidly-Cooling Core in a Merging Cluster
Taweewat Somboonpanyakul, Michael McDonald, Matthew Bayliss +6
We present high-resolution optical images from the Hubble Space Telescope, X-ray images from the Chandra X-ray Observatory, and optical spectra from the Nordic Optical Telescope fo…
The Clusters Hiding in Plain Sight (CHiPS) survey: Complete sample of extreme BCG clusters
Taweewat Somboonpanyakul, Michael McDonald, Massimo Gaspari +2
We present optical follow-up observations for candidate clusters in the Clusters Hiding in Plain Sight (CHiPS) survey, which is designed to find new galaxy clusters with extreme ce…
