Recent star formation in nearby 3CR radio-galaxies from UV HST observations
Ranieri D. Baldi, Alessandro Capetti
We analyzed HST images of 31 nearby (z <~ 0.1) 3CR radio-galaxies. We compared their UV and optical images to detect evidence of recent star formation. Six objects were excluded be…
Optical spectroscopy of 3CR sample of radio sources at z<0.3
Sara Buttiglione, Alessandro Capetti, Annalisa Celotti
We are carrying out a program of optical spectroscopy of the complete subsample of the 3CR catalog of radio sources at redshift z < 0.3. The sample consists of 113 3CR sources, com…
BeppoSax Spectral Survey of soft X-ray selected BL Lacs
A. Wolter, A. Comastri, G. Ghisellini +10
We present X-ray spectra obtained with BeppoSAX (Satellite per Astronomia X) of 10 BL Lac objects, selected from the Einstein Medium Sensitivity and Slew Surveys. We find that in a…
Hipparcos Positioning of Geminga : How and Why
P. A. Caraveo, M. G. Lattanzi, G. Massone +4
Accuracy in the absolute position in the sky is one of the limiting factors for pulsar timing, and timing parameters have a direct impact on the understanding of the physics of Iso…
