A sharper view of the outer Galaxy at 1420 and 408 MHz from the Canadian Galactic Plane Survey II: The catalogue of extended radio sources
A new catalogue of extended radio sources has been prepared based on arcminute-resolution 1420 MHz images from the Canadian Galactic Plane Survey (CGPS). The new catalogue provides both 1420 MHz and 408 MHz flux density measurements on sources found near the Galactic plane in the second quadrant of our Galaxy. In addition cross-identifications are made with other major radio catalogues and info...
متن کاملA 98 % 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 S408MHz > 5 Jy, −30 ◦ ≤ δ ≤ 10◦ and |b| ≥ 10◦. The sample is selected to have similar properties to the northern 3CR revised sample, and to be visible to a combination of existing northern telescopes such as the Very Large Array radio interferometer and the new 8-m class sout...

متن کاملThe 408 MHz B 3 . 2 survey
We present a new 408MHz survey (B3.2) carried out with the “Croce del Nord” radiotelescope in Bologna. The survey coordinates limits are −2◦00′ to +2◦15′ in Dec. and 21h to 24h, 00h to 17h in R.A., equivalent to 0.388 sr. The B3.2 is complete to 0.15 Jy but many sources down to 0.1 Jy are included. Our aim was to select a new and complete sample of Ultra Steep Spectrum (USS) radio sources, as t...
متن کاملThe 408 MHz B 3 . 1 Survey
We present a new 408 MHz survey (B3.1) carried out with the " Croce del Nord " radiotelescope in Bologna. The survey coordinates limits are −2 • 00 ′ to +2 • 15 ′ in Dec. and 21h to 24h, 00h to 17h in R.A., equivalent to 0.388 sr. The B3.1 is complete to 0.15 Jy but many sources down to 0.1 Jy are included. Our aim was to select a new and complete sample of Ultra Steep Spectrum (USS) radio sour...
