The 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 کاملA 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 Deep, High-resolution Survey at 74 Mhz
We present a 74 MHz survey of a 165 deg2 region located near the north Galactic pole. This survey has an unprecedented combination of both resolution (2500 FWHM) and sensitivity ( as low as 24 mJy beam 1). We detect 949 sources at the 5 level in this region, enough to begin exploring the nature of the 74 MHz source population. We present differential source counts, spectral index measurements, ...
