Dense gas formation and destruction in a simulated Perseus-like galaxy cluster with spin-driven black hole feedback
R. S. Beckmann, Y. Dubois, P. Guillard +8
Extended filamentary H emission nebulae are a striking feature of nearby galaxy clusters but the formation mechanism of the filaments, and the processes which shape their morpho…
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…
Driving massive molecular gas flows in central cluster galaxies with AGN feedback
H. R. Russell, B. R. McNamara, A. C. Fabian +7
We present an analysis of new and archival ALMA observations of molecular gas in twelve central cluster galaxies. We examine emerging trends in molecular filament morphology and ga…
Cold gas in a complete sample of group-dominant early-type galaxies
E. O'Sullivan, F. Combes, P. Salomé +7
We present IRAM 30m and APEX telescope observations of CO(1-0) and CO(2-1) lines in 36 group-dominant early-type galaxies, completing our molecular gas survey of dominant galaxies…
Discovery of a diffuse optical line emitting halo in the core of the Centaurus cluster of galaxies: Line emission outside the protection of the filaments
S. L. Hamer, A. C. Fabian, H. R. Russell +6
We present the discovery of diffuse optical line emission in the Centaurus cluster seen with the MUSE IFU. The unparalleled sensitivity of MUSE allows us to detect the faint emissi…
