Extremely Red Galaxies: Old or Dusty ?
Andrea Cimatti, Paola Andreani, Huub Röttgering +1
The nature of the extremely red galaxies is poorly known, the critical issue being whether they are old ellipticals at or distant star-forming galaxies strongly reddened by…
Dust in 3C324
P. N. Best, H. J. A. R"ottgering, M. N. Bremer +6
The results of a deep submillimetre observation using SCUBA of the powerful radio galaxy 3C324, at redshift z=1.206, are presented. At 850 microns, emission from the location of th…
The structure and composition of high redshift radio galaxies
R A E Fosbury, J Vernet, M Villar-Martin +4
Keck spectropolarimetry, giving spectral coverage from Ly- to beyond CIII], and HST imaging of a sample of powerful radio galaxies with \ has been obtained. These data…
Vigorous star formation hidden by dust in a galaxy at
Andrea Cimatti, Paola Andreani, Huub Röttgering +1
Near-infrared surveys have revealed a substantial population of enigmatic faint galaxies with extremely red optical-to-near-infrared colours and with a sky surface density comparab…
The UV radiation from radio galaxies: Keck spectropolarimetry of 4C 23.56 and 4C 00.54
Andrea Cimatti, Sperello di Serego Alighieri, Joël Vernet +2
We present the results of deep spectropolarimetry of two powerful radio galaxies at (4C 00.54 and 4C 23.56) obtained with the W.M. Keck II 10m telescope, aimed at studyi…
BeppoSAX Observations of 2 Jy Lobe-dominated Broad-Line Sources: the Discovery of a Hard X-ray Component
R. Morganti, P. Padovani, J. Siebert +3
We present new BeppoSAX LECS, MECS, and PDS observations of five lobe-dominated, broad-line active galactic nuclei selected from the 2 Jy sample of southern radio sources. These in…
