Radio galaxies at z 2.5: Results from Keck spectropolarimetry
In classifying the ensemble of powerful extragalactic radio sources, considerable evidence has accumulated that radio galaxies and quasars are orientation-dependent manifestations of the same parent
Massive Star Formation in a Gravitationally Lensed H II Galaxy at z = 3.357* ** ***
The Lynx arc, with a redshift of 3.357, was discovered during spectroscopic follow-up of the z ¼ 0:570 cluster RX J0848+4456 from the ROSAT Deep Cluster Survey. The arc is characterized by a very red
Deep spectroscopy of the FUV–optical emission lines from a sample of radio galaxies at z∼ 2.5: metallicity and ionization*
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 revisit in this paper the location of the various components observed in the AGN of NGC 1068. Discrepancies between previously published studies are explained, and a new measurement for the
The origin of the UV excess in powerful radio galaxies: spectroscopy and polarimetry of a complete sample of intermediate‐redshift radio galaxies
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
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
The radio structures of southern 2-Jy radio sources: New ATCA and VLA radio images
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
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.
Keck Observations of the Hidden Quasar IRAS P09104+4109
We present imaging and spectropolarimetric observations of the ultraluminous infrared galaxy IRAS P09104+4109 using the Keck 10 m Telescope. We detect the clear presence of broad Hβ, Hγ, and Mg II
Starburst radio galaxies: general properties, evolutionary histories and triggering
In this paper we discuss the results of a programme of spectral synthesis modelling of a sample of starburst radio galaxies in the context of scenarios for the triggering of the activity and the
