Molecular Gas in the Halo Fuels the Growth of a Massive Cluster Galaxy at High Redshift
B. H. C. Emonts, M. D. Lehnert, M. Villar-Martin +19
The largest galaxies in the Universe reside in galaxy clusters. Using sensitive observations of carbon-monoxide, we show that the Spiderweb Galaxy -a massive galaxy in a distant pr…
A CO-rich merger shaping a powerful and hyper-luminous infrared radio galaxy at z=2: the Dragonfly Galaxy
B. H. C. Emonts, M. Y. Mao, A. Stroe +17
In the low-redshift Universe, the most powerful radio sources are often associated with gas-rich galaxy mergers or interactions. We here present evidence for an advanced, gas-rich…
The Discovery of Radio Stars within 10 arcseconds of Sgr A* at 7mm
F. Yusef-Zadeh, D. A. Roberts, H. Bushouse +4
Very Large Array observations of the Galactic Center at 7 mm have produced an image of the 30 arcseconds surrounding Sgr A* with a resolution of 82x42 milliarcseconds (mas). A comp…
A relation between circumnuclear HI, dust, and optical cores in low-power radio galaxies
Ilse M. van Bemmel, Raffaella Morganti, Tom Oosterloo +1
From new observations and literature data we investigate the presence of HI, dust, and optical cores in the central kiloparsec of low-power radio galaxies. The goal of this pilot s…
Large-scale HI in nearby radio galaxies (II): the nature of classical low-power radio sources
B. H. C. Emonts, R. Morganti, C. Struve +7
An important aspect of solving the long-standing question as to what triggers various types of Active Galactic Nuclei involves a thorough understanding of the overall properties an…
Is cold gas fuelling the radio galaxy NGC 315?
R. Morganti, A. B. Peck, T. A. Oosterloo +5
We present WSRT, VLA and VLBI observations of the HI absorption in the radio galaxy NGC 315. The main result is that two HI absorbing systems are detected against the central regio…
The disc-dominated host galaxy of FR-I radio source B2 0722+30
B. H. C. Emonts, C. N. Tadhunter, R. Morganti +4
We present new observational results that conclude that the nearby radio galaxy B2 0722+30 is one of the very few known disc galaxies in the low-redshift Universe that host a class…
Deep H I Survey of the Spiral Galaxy NGC 2403
Filippo Fraternali, Gustaaf van Moorsel, Renzo Sancisi +1
High sensitivity H I observations of the nearby spiral galaxy NGC 2403 obtained with the VLA are presented and discussed. The properties of the extended, differentially rotating H…
Large-scale gas disk around the radio galaxy Coma A
R. Morganti, T. A. Oosterloo, S. Tinti +3
We present WSRT and VLA radio observations of the neutral hydrogen in the radio galaxy Coma A. We detect extended HI absorption against both radio lobes of Coma A, at distances of…
A new, kinematically anomalous HI component in the spiral galaxy NGC 2403
Filippo Fraternali, Tom Oosterloo, Renzo Sancisi +1
We discuss new, high sensitivity HI observations of the spiral galaxy NGC2403 which show extended emission at anomalous velocities with respect to the `cold' disk. This `anomalous'…
Stars & Gas in the Galaxy Pair II Zw 70/71
A. L. Cox, L. S. Sparke, A. M. Watson +1
II Zw 71 (UGC 9562) was classified as a ``probable'' polar-ring galaxy in the Polar-Ring Catalog, based upon its optical appearance. We present 21 cm and optical observations of th…
HI absorption in radio galaxies: effect of orientation or interstellar medium?
R. Morganti, T. A. Oosterloo, C. N. Tadhunter +3
A search for HI absorption has been made in 23 radio galaxies using the ATCA, the VLA and the WSRT. In five galaxies HI absorption was detected. We investigate how the detection ra…
