Gas condensation in brightest group galaxies unveiled with MUSE. Morphology and kinematics of the ionized gas

Olivares, V.; Salomé, P.; Hamer, S. L.; Combes, F.; Gaspari, M.; Kolokythas, K.; O'Sullivan, Ewan; Beckmann, R. S.; Babul, A.; Polles, F. L.; Lehnert, M.; Loubser, S. I.; Donahue, M.; Gendron-Marsolais, M. -L; Lagos, P.; Pineau des Forets, G.; Godard, B.; Rose, T.; Tremblay, Grant; Ferland, G.; Guillard, P. (2022)

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 local (z = 0.017) brightest group galaxies ...
Ubiquitous cold and massive filaments in cool core clusters

Olivares, V.; Salome, P.; Combes, F.; Hamer, S.; Guillard, P.; Lehnert, M. D.; Polles, F. L.; Beckmann, R. S.; Dubois, Y.; Donahue, M.; Edge, A.; Fabian, A. C.; McNamara, B.; Rose, T.; Russell, H. R.; Tremblay, Grant; Vantyghem, A.; Canning, R. E. A.; Ferland, G.; Godard, B.; Peirani, S.; Pineau des Forets, G. (2019)

Multi-phase filamentary structures around brightest cluster galaxies (BCG) are likely a key step of AGN-feedback. We observed molecular gas in three cool cluster cores, namely Centaurus, Abell S1101, and RXJ1539.5, and ...
