Abstract We have studied the kinematic properties of the ionized gas outflows and ambient interstellar medium (ISM) in a large and representative sample of local U/LIRGs (58 systems, 75 galaxies) at…
The radio structures of southern 2-Jy radio sources: New ATCA and VLA radio images
- R. Morganti, T. Oosterloo, C. Tadhunter, R. Aiudi, P. Jones, M. Villar-Martin
- Physics
- 15 August 1993
We present new radio images obtained with the Australia Telescope Compact Array (ATCA) and the Very Large Array (VLA) for a group of 14 galaxies belonging to the 2-Jy sample of radio sources. The new…

We present long-slit near-infrared (NIR) spectra, obtained using the Infrared Spectrometer And Array Camera (ISAAC) instrument at the Very Large Telescope, which sample the rest-frame optical…
Revisiting the location and environment of the central engine in NGC 1068

We present spectroscopic and polarimetric observations of a complete, optically unbiased sample of 2-Jy radio galaxies at intermediate redshifts (0.15 10 per cent level. Careful measurement and…
The large-scale distribution of warm ionized gas around nearby radio galaxies with jet-cloud interactions

- 8 February 2000
Deep, narrow-band Hα observations taken with the TAURUS Tunable Filter on the 4.2-m William Herschel Telescope are presented for two nearby radio galaxies with strong jet–cloud interactions. Although…
Molecular gas in the halo fuels the growth of a massive cluster galaxy at high redshift

Using sensitive observations of carbon monoxide, it is shown that the Spiderweb galaxy—a massive galaxy in a distant protocluster—is forming from a large reservoir of molecular gas, supporting the notion that giant galaxies in clusters formed from extended regions of recycled gas at high redshift.
CO(1-0) detection of molecular gas in the massive Spiderweb Galaxy (z = 2)
The high-redshift radio galaxy MRC 1138−262 (‘Spiderweb Galaxy’; z = 2.16) is one of the most massive systems in the early Universe and surrounded by a dense ‘web’ of proto-cluster galaxies. Using…
