Young Stars and Nonstellar Emission in the Aligned Radio Galaxy 3C 256
We present ground-based images of the z = 1.824 radio galaxy 3C 256 in the standard BVRIJHK filters and an interference filter centered at 8800 A, a Hubble Space Telescope image in a filter dominatedExpand
3C 17: The BCG of a galaxy cluster at z=0.22
Gemini Multi Object Spectrograph medium-resolution spectra and photometric data of 39 objects in the field of the radio galaxy 3C 17 are presented. Based on the new data, a previously uncatalogedExpand
Clustering on very small scales from a large sample of confirmed quasar pairs: does quasar clustering track from Mpc to kpc scales?
We present the most precise estimate to date of the clustering of quasars on very small scales, based on a sample of 47 binary quasars with magnitudes of g < 20.85 and proper transverse separationsExpand
In Pursuit of High Redshift Galaxies
Some contributions in Chap. 1 have highlighted the impact of the discovery in the 1960s of a handful of radio galaxies and Quasars in the redshift range z ∼ 0.2–0.4. About 40 years later, at the endExpand
8.4 GHz High-Resolution Observations of Fanaroff-Riley II 3CR Radio Sources with 0.3 < z < 2.0. II. Ten New Images
VLA observations at 8.4 GHz of two Fanaroff-Riley class II (FR II) radio galaxies (RGs; 3C 265 and 3C 324) and eight FR II quasars (QSRs; 3C 175, 3C 204, 3C 215, 3C 249.1, 3C 263, 3C 336, 3C 351, andExpand
A search for distant radio galaxies from SUMSS and NVSS – III. Radio spectral energy distributions and the z–α correlation
This is the third in a series of papers that present observations and results for a sample of 76 ultrasteep-spectrum radio sources designed to find galaxies at high redshift. Here we presentExpand
Lyman-Break Galaxies
■ Abstract In this paper we review the properties of Lyman-break galaxies, namely starburst galaxies at high redshifts, approximately in the range 2:5 2:5, including1000 spectroscopic redshifts andExpand
The balance between shocks and AGN photoionization in radio sources and its relation to the radio size
We have analyzed the ultraviolet and optical emission line ratios of a large sample of extragalactic radio sources (QSOs and radio galaxies), with the help of models combining AGN photoionization andExpand
A submillimetre survey of the star formation history of radio galaxies
We present the results of the first major systematic submillimetre survey of radio galaxies spanning the redshift range 1 2.5, and the average submillimetre luminosity rises at a rate ∝(1+z)3 out toExpand
A 98 per cent spectroscopically complete sample of the most powerful equatorial radio sources at 408 MHz
A new sample of very powerful radio galaxies is defined from the Molonglo Reference Catalogue, according to the criteria S408 MHz>5 Jy, −30°≤δ≤10° and |b|≥10°. The sample is selected to have similarExpand
