The origin of the X-ray, radio and HI structures in the NGC 5903 galaxy group
Ewan O'Sullivan, Konstantinos Kolokythas, Nimisha G. Kantharia +3
The NGC 5903 galaxy group is a nearby (~30 Mpc) system of ~30 members, dominated by the giant ellipticals NGC 5903 and NGC 5898. The group contains two unusual structures, a ~110 k…
ALMA observations of molecular clouds in three group centered elliptical galaxies: NGC 5846, NGC 4636, and NGC 5044
Pasquale Temi, Alexandre Amblard, Myriam Gitti +4
We present new ALMA CO(2--1) observations of two well studied group-centered elliptical galaxies: NGC~4636 and NGC~5846. In addition, we include a revised analysis of Cycle 0 ALMA…
Role of Electon Excitation and Nature of Molecular Gas in Cluster Central Elliptical Galaxies
Jeremy Lim, Dinh-V-Trung, Jan Vrtilek +2
We present observations in CO(3-2) that, combined with previous observations in CO(2-1), constrain the physical properties of the filamentary molecular gas in the central 6.5…
The Complete Local Volume Groups Sample - I. Sample Selection and X-ray Properties of the High-Richness Subsample
Ewan O'Sullivan, Trevor J. Ponman, Konstantinos Kolokythas +7
We present the Complete Local-Volume Groups Sample (CLoGS), a statistically complete optically-selected sample of 53 groups within 80 Mpc. Our goal is to combine X-ray, radio and o…
NGC 741 - Mergers and AGN feedback on galaxy group scale
G. Schellenberger, J. M. Vrtilek, L. David +5
Low mass galaxy cluster systems and groups play an essential role in upcoming cosmological studies such as those to be carried out with eROSITA. Though the effects of active galact…
The Presence of Thermally Unstable X-ray Filaments and the Production of Cold Gas in the NGC 5044 Group
Laurence P. David, Jan Vrtilek, Ewan O'Sullivan +3
We present the results of a deep Chandra observation of the X-ray bright, moderate cooling flow group NGC 5044 along with the observed correlations between the ionized, atomic, and…
