Exploring the spectroscopic properties of relic radiogalaxies
Alessandro Capetti, Andrew Robinson, Ranieri D. Baldi +4
From an optical spectroscopic survey of 3CR radiogalaxies (RGs) with z<0.3, we discovered three objects characterized by an extremely low level of gas excitation and a large defici…
Extended soft X-ray emission in 3CR radio galaxies at z < 0.3: High Excitation and Broad Line Galaxies
B. Balmaverde, A. Capetti, P. Grandi +11
We analyze Chandra observations of diffuse soft X-ray emission associated with a complete sample of 3CR radio galaxies at z < 0.3. In this paper we focus on the properties of the s…
An optical spectroscopic survey of the 3CR sample of radio galaxies with z<0.3. IV. Discovery of the new spectroscopic class of relic radio galaxies
Alessandro Capetti, Sara Buttiglione, David J. Axon +6
From an optical spectroscopic survey of 3CR radio galaxies with z<0.3, we discovered a new spectroscopic class of powerful radio-loud AGN. The defining characteristics of these gal…
The 1.6 micron near infrared nuclei of 3C radio galaxies: Jets, thermal emission or scattered light?
R. D. Baldi, M. Chiaberge, A. Capetti +6
Using HST NICMOS 2 observations we have measured 1.6-micron near infrared nuclear luminosities of 100 3CR radio galaxies with z<0.3, by modeling and subtracting the extended emissi…
An optical spectroscopic survey of the 3CR sample of radio galaxies with z<0.3. III. Completing the sample
Sara Buttiglione, Alessandro Capetti, Annalisa Celotti +4
We present optical nuclear spectra for nine 3CR radio sources obtained with the Telescopio Nazionale Galileo, that complete our spectroscopic observations of the sample up to redsh…
Three candidate clusters of galaxies at redshift ~1.8: the "missing link" between protoclusters and local clusters?
M. Chiaberge, A. Capetti, F. D. Macchetto +3
We present three candidate clusters of galaxies at redshifts most likely between 1.7 and 2.0, which corresponds to a fundamentally unexplored epoch of clusters evolution. The candi…
