The relationship between warm and hot gas-phase metallicity in massive elliptical galaxies and the influence of AGN feedback

Valeria Olivares, Yuanyuan Su, Pasquale Temi +10

Warm ionized gas is ubiquitous at the centers of X-ray bright elliptical galaxies. While it is believed to play a key role in the feeding and feedback processes of supermassive bla…

1321+045: a Compact Steep Spectrum radio source in a cool-core galaxy cluster

Ewan O'Sullivan, Magdalena Kunert-Bajraszewska, Aneta Siemiginowska +4

Cluster-central gigahertz peak and compact steep spectrum (CSS) sources offer an opportunity to study the earliest phases of AGN feedback, but few have yet been examined in detail.…

Molecular gas along the old radio jets of the cluster-central type 2 quasar IRAS 09104+4109

Ewan O'Sullivan, Françoise Combes, Arif Babul +4

We present Northern Extended Millimeter Array (NOEMA) CO(2-1) maps of the z=0.4418 cluster-central QSO IRAS 09104+4109, which trace ~4.5x10^10 Msol of molecular gas in and around t…

Atacama Compact Array Measurements of the Molecular Mass in the NGC 5044 Cooling Flow Group

Gerrit Schellenberger, Laurence P. David, Jan Vrtilek +13

The fate of cooling gas in the centers of galaxy clusters and groups is still not well understood, as is also the case for the complex processes of triggering star formation in cen…

Environmental processing in cluster core galaxies at z=1.7

G. Castignani, F. Combes, P. Salomé

Today, the brightest cluster galaxies (BCGs) are passive and very massive galaxies at the center of their clusters, and they still accrete mass through swallowing companions and ga…

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…
