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 Correlation Interferometer for 408 MHz
One day in the 1980’s I was helping a visiting scientist get his experiment set up at a remote site to the west of Ottawa. This site contained the decaying remains of decades of radio experiments. Among some trees I found an old shed, crammed to the roof with yagi antennas, combiners, hybrids and many matched lengths of heliax coaxial cable. Many were broken, but mixed in with the debris were s...
متن کاملROSAT all-sky survey map of the Cygnus Loop: Overall structure and comparison with radio map
The Cygnus Loop is one of the largest and nearest supernova remnants. It was observed by the PSPC detector of the Röntgen-Satellite ROSAT during the survey phase of the ROSAT mission. This has resulted in the highest–sensitivity complete x-ray image of the Cygnus Loop. It also has the high spatial resolution of one arcmin and contains spectral information. It is thus the best map of the Cygnus ...
متن کاملThe ROSAT all-sky survey bright source catalogue
We present the ROSAT All-Sky Survey Bright Source Catalogue (RASS-BSC, revision 1RXS) derived from the all-sky survey performed during the first half year (1990/91) of the ROSAT mission. 18,811 sources are catalogued (i) down to a limiting ROSAT PSPC count-rate of 0.05 cts s−1 in the 0.1−2.4 keV energy band, (ii) with a detection likelihood of at least 15 and (iii) at least 15 source counts. Th...
