Polarisation Observations at Jodrell Bank Observatory
Some of the issues concerning polarisation calibration in the context of pulsar observations are outlined along with the existing calibration system in Jodrell Bank Observatory. The principle behind the back-calibration of the Jodrell Bank database of 16 years is presented along with plans for exploiting the database in the future.
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 کاملCMB observations with the Jodrell Bank – IAC interferometer at 33 GHz
The paper presents the first results obtained with the Jodrell Bank – IAC two-element 33 GHz interferometer. The instrument was designed to measure the level of the Cosmic Microwave Background (CMB) fluctuations at angular scales of 1 • − 2 •. The observations analyzed here were taken in a strip of the sky at Dec=+41 • with an element separation of 16.7 λ, which gives a maximum sensitivity to ∼...
متن کاملThe Caltech–Jodrell Bank VLBI Surveys
The Caltech–Jodrell Bank VLBI surveys of bright extragalactic radio sources north of declination 35 were carried out between 1990 and 1995 using the Mark-II system, achieving images with a resolution of about 1 mas at 5 GHz. The CJ1 survey (together with the older ‘PR’ survey) includes 200 objects with 5 GHz flux density greater than 0.7 Jy; the CJ2 survey includes 193 flat-spectrum sources wit...
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...
