Molecular gas in distant brightest cluster galaxies
G. Castignani, F. Combes, P. Salomé +1
The stellar mass assembly of brightest cluster galaxies (BCGs) is still debated. We have observed in CO with the IRAM-30m two star forming BCGs belonging to SpARCS clusters, 3C 244…
A CO molecular gas wind 340 pc away from the Seyfert 2 nucleus in ESO 420-G13 probes an elusive radio jet
J. A. Fernández-Ontiveros, K. M. Dasyra, E. Hatziminaoglou +11
A prominent jet-driven outflow of CO(2-1) molecular gas is found along the kinematic minor axis of the Seyfert 2 galaxy ESO 420-G13, at a distance of from the n…
Probing the merger history of red early-type galaxies with their faint stellar substructures
B. Mancillas, P. -A. Duc, F. Combes +4
Several deep observations such as those carried out at the Canada-France-Hawaii Telescope (CFHT) have revealed prominent Low Surface Brightness (LSB) fine structures that change th…
Molecular clouds in the Cosmic Snake normal star-forming galaxy 8 billion years ago
Miroslava Dessauges-Zavadsky, Johan Richard, Françoise Combes +12
The cold molecular gas in contemporary galaxies is structured in discrete cloud complexes. These giant molecular clouds (GMCs), with - solar masses and radii of 5-100 p…
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…
Towards sub-kpc scale kinematics of molecular and ionized gas of star-forming galaxies at
M. Girard, M. Dessauges-Zavadsky, F. Combes +4
We compare the molecular and ionized gas kinematics of two strongly lensed galaxies at based on observations from ALMA and MUSE. We derive the CO and [OII] rotation curves…
