Turbulent circumnuclear disc and cold gas outflow in the newborn radio source 4C 31.04
Suma Murthy, Raffaella Morganti, Tom Oosterloo +2
We present deep kpc- and pc-scale neutral atomic hydrogen (HI) absorption observations of a very young radio source (< 5000 yrs), 4C 31.04, using the WSRT and the Global VLBI array…
Cold gas in the heart of Perseus A
Raffaella Morganti, Suma Murthy, Tom Oosterloo +6
We present new JVLA and VLBA observations tracing the HI in the central region of 3C84 (Perseus A). This radio source is hosted by the bright cluster galaxy NGC 1275 in the centre…
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…
PKS 1954-388: RadioAstron Detection on 80,000 km Baselines and Multiwavelength Observations
P. G. Edwards, Y. Y. Kovalev, R. Ojha +24
We present results from a multiwavelength study of the blazar PKS 1954-388 at radio, UV, X-ray, and gamma-ray energies. A RadioAstron observation at 1.66 GHz in June 2012 resulted…
