    Spectra of Extended Extragalactic Radio Sources (1969)
    [s.l.] : Nature Publishing Group
    Nature 224 (1969), S. 889-890 
    Details
    ISSN: 1476-4687

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] Scheuer and Williams5 and Kellermann et al.6 have recently pointed out that the spectra of the total emission from many of these sources do not deviate appreciably from a power law in which the received flux density S(n) varies with observing frequency n as S(n) = Cn-a, where C and a are constants. ...

    New extragalactic variable sources from an 8-GHz survey (1974)
    [s.l.] : Nature Publishing Group

    Details
    ISSN: 1476-4687

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] We observed every 8-GHz survey source less than 1' in diameter that would not be significantly confused using the 4.7' resolution of the 300-foot telescope at 2.7 GHz. A three-feed system was used to determine declination pointing corrections at every source transit, so that flux densities could be ...

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] Observations of the flux density of radiation from the Crab nebula at frequencies below ~40 MHz must be corrected for absorption by free-free transitions of electrons in the intervening interstellar medium to determine the spectrum of the emitted radiation. The interstellar absorption along the ...

    Notes: [Auszug] A giant radio source with an unusual Z-shaped structure extending over nearly one degree on the sky has been detected around the nearby elliptical galaxy NGC315. The source has structure aligned with the minor axis of the optical galaxy on linear scales ranging from a few tens of kpc to ∼ 1.7 ...

    Notes: [Auszug] We have used the 46 m paraboloid at the Algonquin Radio Observatory to search for more sources with opaque microwave spectra within 10 of the galactic equator and between galactic longitudes 15 and 235. Ninety-one sources already catalogued and satisfying one of the following criteria were ...

    Notes: [Auszug] We consider here the 10 MHz observations of galactic sources with known distances, and of sources identified with extragalactic objects at |bII| 〈 20. For these sources the length of the line of sight through the interstellar medium can be estimated, and the observed absorption provides data on ...

    Notes: [Auszug] Since 1965 we have used the 10.03 MHz array2 at the Dominion Radio Astrophysical Observatory for studies of discrete radio sources. Our instrument has an angular resolution and reception bandwidth similar to those of the Ukrainian UTR-1 array3 when this is operated at 10 MHz. The two arrays are at ...
