The angular momentum of disc galaxies at z=1
A. Marasco, F. Fraternali, L. Posti +3
We investigate the relation between stellar mass and specific stellar angular momentum, or `Fall relation', for a sample of 17 isolated, regularly rotating disc galaxies at z=1. Al…
Early Observations of the MHONGOOSE Galaxies: Getting Ready for MeerKAT
A. Sorgho, C. Carignan, D. J. Pisano +9
We present early observations of 20 galaxies in the MHONGOOSE survey galaxies using KAT-7, the GBT, and MeerKAT. We present the best calibrators for five of the MHONGOOSE galaxies…
A GBT Survey of the HALOGAS Galaxies and Their Environments I: Revealing the full extent of HI around NGC891, NGC925, NGC4414 & NGC4565
N. M. Pingel, D. J. Pisano, G. Heald +7
We present initial results from a deep neutral hydrogen (HI) survey of the HALOGAS galaxy sample, which includes the spiral galaxies NGC891, NGC925, NGC4414, and NGC4565, performed…
BST1047+1156: An extremely diffuse and gas-rich object in the Leo I Group
J. Christopher Mihos, Christopher T. Carr, Aaron E. Watkins +2
We report the detection of diffuse starlight in an extragalactic HI cloud in the nearby Leo~I galaxy group. We detect the source, dubbed BST1047+1156, in both broadband optical and…
Young radio jets breaking free: molecular and HI outflows in their centers
Raffaella Morganti, Tom Oosterloo, Robert Schulz +2
Our view of the central regions of AGN has been enriched by the discovery of fast and massive outflows of HI and molecular gas. Here we present a brief summary of results obtained…
The interstellar and circumnuclear medium of active nuclei traced by HI 21-cm absorption
Raffaella Morganti, Tom Oosterloo
This review summarises what we have learnt in the last two decades based on HI 21-cm absorption observations about the cold interstellar medium (ISM) in the central regions of acti…
Probing multi-phase outflows and AGN feedback in compact radio galaxies: the case of PKSB 1934-63
F. Santoro, M. Rose, R. Morganti +3
Young radio AGN are pivotal for our understanding of many of the still-debated aspects of AGN feedback. In this paper we present a study of the interstellar medium in the compact,…
Mapping the neutral atomic hydrogen gas outflow in the restarted radio galaxy 3C 236
R. Schulz, R. Morganti, K. Nyland +3
The energetic feedback that is generated by radio jets in active galactic nuclei (AGNs) has been suggested to be able to produce fast outflows of atomic hydrogen (HI) gas that can…
Galaxy interactions in loose galaxy groups: KAT-7 and VLA HI Observations of the IC 1459 group
T. A. Oosterloo, M. -L. Zhang, D. M. Lucero +1
We report on the results from deep HI observations, performed with the Karoo Array Telescope and with the Karl G. Jansky Very Large Array of the loose galaxy group centred on the e…
The jet-ISM interactions in IC 5063
Dipanjan Mukherjee, Alex Y. Wagner, Geoffrey V. Bicknell +4
The interstellar medium of the radio galaxy IC 5063 is highly perturbed by an AGN jet expanding in the gaseous disc of the galaxy. We model this interaction with relativistic hydro…
ALMA observations of AGN fuelling: the case of PKS B1718-649
F. M. Maccagni, R. Morganti, T. A. Oosterloo +2
We present ALMA observations of the CO (2--1) line of the newly born ( years) active galactic nucleus (AGN), PKS B1718-649. These observations reve…
