A CO Detection in a Massive Molecular Gas Flow in Abell 1795's Central Galaxy
J. A. Gray, H. R. Russell, F. Combes +6
We present new ALMA CO(2-1) observations of the central galaxy in the cool-core cluster Abell 1795, targeting the origin of extended molecular filaments. The filaments ext…
A XRISM Observation of the Archetypal Radio-Mode Feedback System Hydra-A: Measurements of Atmospheric Motion and Constraints on Turbulent Dissipation
Tom Rose, B. R. McNamara, Julian Meunier +14
We present XRISM Resolve observations centered on Hydra-A, a redshift z = 0.054 brightest cluster galaxy which hosts one of the largest and most powerful FR-I radio sources in the…
Two distinct molecular cloud populations detected in massive galaxies
Tom Rose, B. R. McNamara, F. Combes +8
We present new ALMA observations of CO, CN, CS, HCN and HCO absorption seen against the bright and compact radio continuum sources of eight massive galaxies. Combined with ar…
A massive multiphase plume of gas in Abell 2390's brightest cluster galaxy
Tom Rose, B. R. McNamara, F. Combes +6
We present new ALMA CO(2-1) observations tracing solar masses of molecular gas in Abell 2390's brightest cluster galaxy, where half the gas is located in a one…
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…
Does absorption against AGN reveal supermassive black hole accretion?
Tom Rose, B. R. McNamara, F. Combes +7
Galaxies often contain large reservoirs of molecular gas which shape their evolution. This can be through cooling of the gas -- which leads to star formation, or accretion onto the…
Circumnuclear Medium around the Central AGN in a Cool-Core Cluster, Abell 1644-South
Junhyun Baek, Aeree Chung, Alastair Edge +3
We present the circumnuclear multi-phase gas properties of the brightest cluster galaxy (BCG) in the center of Abell 1644-South. A1644-S is the main cluster in a merging system, wh…
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…
Illuminating Galaxy Evolution at Cosmic Noon with ISCEA: the Infrared Satellite for Cosmic Evolution Astrophysics
Yun Wang, Lee Armus, Andrew Benson +18
ISCEA (Infrared Satellite for Cosmic Evolution Astrophysics) is a small astrophysics mission whose Science Goal is to discover how galaxies evolved in the cosmic web of dark matter…
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 variability of brightest cluster galaxies at high radio frequencies
Tom Rose, Alastair Edge, Sebastian Kiehlmann +6
Variability of a galaxy's core radio source can be a significant consequence of AGN accretion. However, this variability has not been well studied, particularly at high radio frequ…

Tom Rose, A. C. Edge, F. Combes +16
We present Atacama Large Millimeter/submillimeter Array observations of the brightest cluster galaxy Hydra-A, a nearby () giant elliptical galaxy with powerful and extende…
Constraining cold accretion onto supermassive black holes: molecular gas in the cores of eight brightest cluster galaxies revealed by joint CO and CN absorption
Tom Rose, A. C. Edge, F. Combes +18
To advance our understanding of the fuelling and feedback processes which power the Universe's most massive black holes, we require a significant increase in our knowledge of the m…
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…
Deep and narrow CO absorption revealing molecular clouds in the Hydra-A brightest cluster galaxy
Tom Rose, A. C. Edge, F. Combes +20
Active galactic nuclei play a crucial role in the accretion and ejection of gas in galaxies. Although their outflows are well studied, finding direct evidence of accretion has prov…
