“…We found that, in addition to the highly perturbed gas, all objects are embedded in giant (often ≥100 kpc), low surface brightness nebulae of metal rich, ionized gas with quiescent kinematics, with FWHM and velocity shifts of ∼several hundred km s −1 (Villar-Martín et al 2002, 2003. With the goal of investigating the kinematic, ionizaton and morphological properties of the nebulae in two spatial dimensions, we started an observational program of 3D integral field spectroscopy with the fiber-fed integral field spectrographs Vimos on VLT and PMAS/PPAK on the 3.5m telescope in Calar Alto.…”

High redshift radio galaxies (z ≥2) are believed to be progenitors of the giant ellipticals of today. They are often associated with giant Lyα nebulae (sometimes >100 kpc), which have been for more than two decades valuable sources of information about the evolutionary status of the host galaxy and its chemical enrichment and star formation histories.I present in this paper a summary of the most relevant results about the giant nebulae obtained in the last ∼10 years and the implications on our understanding of the early phases of evolution of massive elliptical galaxies. An interesting earlier review can be found in McCarthy (1993).

Aims. To investigate the impact of radio jets during the formation epoch of their massive host galaxies, we present an analysis of two massive, log M stellar /M ∼ 10.6 and 11.3, compact radio galaxies at z = 3.5, TNJ0205+2242 and TNJ0121+1320. Their small radio sizes (R ≤ 10 kpc) are most likely a sign of youth. In particular, we compare their radio properties and gas dynamics with those in well extended radio galaxies at high redshift, which show strong evidence for powerful, jet-driven outflows of significant gas masses (M ∼ 10 9−10 M ). Methods. Our analysis combines rest-frame optical integral-field spectroscopy obtained with SINFONI on the VLT with existing radio imaging, CO(4-3) emission line spectra, and rest-frame UV longslit spectroscopy. Results.[OIII]λ5007 line emission is compact in both galaxies and lies within the region defined by the radio lobes. For TNJ0205+2242, the Lyα profile narrows significantly outside the jet radius, indicating the presence of a quiescent halo. TNJ0121+1320 has two components at a projected relative distance of ∼10 kpc and a velocity offset of ∼300 km s −1 , measured from the [OIII]λ5007 velocity map. This suggests that the fainter component is orbiting around the more massive, radio-loud galaxy. If motions are gravitational, this implies a dynamical mass of 2 × 10 11 M for the radio-loud component. Conclusions. The dynamical mass, molecular gas mass measured from the CO line emission, and radio luminosity of these two compact radio galaxies imply that compact radio sources may well develop large-scale, energetic outflows as observed in extended radio galaxies, with the potential of removing significant fractions of the ISM from the host galaxy. The absence of luminous emission line gas extending beyond the radio emission in these sources agrees with the observed timescales and outflow rates in extended radio galaxies, and adds further evidence that the energetic, large-scale outflows observed in extended radio sources (Nesvadba et al. 2006, ApJ, 650, 693) are indeed the result of influence of the radio jet.

Abstract. We present results of a comprehensive multi-frequency study of the radio galaxy B3 J2330+3927. The 1. 9 wide radio source, consisting of 3 components, is bracketed by 2 objects in our Keck K-band image. Optical and near-IR Keck spectroscopy of these two objects yield z = 3.087 ± 0.004. The brightest (K = 18.8) object has a standard type II AGN spectrum, and is the most likely location of the AGN, which implies a one-sided jet radio morphology. Deep 113 GHz observations with the IRAM Plateau de Bure Interferometer reveal CO J = 4−3 emission, which peaks at the position of the AGN. The CO line is offset by 500 km s −1 from the systemic redshift of the AGN, but corresponds very closely to the velocity shift of an associated H I absorber seen in Lyα. This strongly suggests that both originate from the same gas reservoir surrounding the AGN host galaxy. Simultaneous 230 GHz interferometer observations find a ∼3× lower integrated flux density when compared to single dish 250 GHz observations with MAMBO at the IRAM 30 m telescope. This can be interpreted as spatially resolved thermal dust emission at scales of 0. 5 to 6 . Finally, we present a τ < 1.3% limit to the H I 21 cm absorption against the radio source, which represents the seventh nondetection out of 8 z > 2 radio galaxies observed to date with the WSRT. We present mass estimates for the atomic, neutral, and ionized hydrogen, and for the dust, ranging from M(H I) = 2 × 10 7 M derived from the associated H I absorber in Lyα up to M(H 2 ) = 7 × 10 10 M derived from the CO emission. This indicates that the host galaxy is surrounded by a massive reservoir of gas and dust. The K-band companion objects may be concentrations within this reservoir, which will eventually merge with the central galaxy hosting the AGN.
