    A Relaxation Oscillation Maintained by Discharge Corona (1957)
    [s.l.] : Nature Publishing Group
    Nature 179 (1957), S. 707-708 
    Details
    ISSN: 1476-4687
    Source: Nature Archives 1869 - 2009
    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] TRICHEL1 showed in 1938 that corona from a J. negative point consists of pulses of very short duration, which often occur at a well-defined frequency. The pulse frequency is roughly proportional to the corona current, and ranges from a few cycles per second to the radio frequencies. A general ...

    A High-Resolution Survey of the Coma Cluster of Galaxies at 408 Mc./s. (1959)
    [s.l.] : Nature Publishing Group
    Nature 183 (1959), S. 1663-1664 
    Details
    ISSN: 1476-4687

    Notes: [Auszug] These results.confirm the earlier report by Seeger, Westerhout and Conway2 that radiation is detectable from the vicinity of the Coma cluster. The new feature of the present survey is the resolution of this radio emission into at least three distinct sources, A, B and C (see Table 1). Of these ...

    Notes: [Auszug] The system was designed to detect periodic signals in the range of periods 0-2〈P〈3-6s. The outputs of two receivers, each with 4 MHz bandwidth and detecting the two hands of circular polarization, were combined, and the detected signal was sampled digitally every 50 ms over a period of 13m 39 ...

    Notes: [Auszug] Physical parameters of the four pulsars are given in Table 1, together with the details of the pulsar MP 1240 for comparison with MP 1154. The pulsars MP 1706 and MP 1911 are weak and erratic when observed with our 4 MHz bandwidth at 408 MHz. The pulsar MP 0254 has been reasonably strong on the few ...

    Notes: [Auszug] The physical parameters of the three pulsars are given in Table 1. MP 1642 has a small ratio of pulse width to period of 1-3 per cent compared with the average of about 4 per cent1. Only three or four other pulsars have pulse width to period ratios as small as this. In other respects, the values of ...

    Notes: [Auszug] The observations were made at 408 MHz using the fan beam of the east-west arm of the Molonglo Radio Telescope. The bandwidth of the telescope was divided to form two narrower channels separated in frequency. The pulses received in each channel were recorded using a multiple channel ultraviolet ...

    Notes: [Auszug] The search technique of "early" and "late" beams1 was used in the observations. In addition, the centre beam signal was split into two frequency bands centred at 407 MHz and 409 MHz. The recording of the pulse arrival times in the two bands, using a magnetic tape recorder, allows measurement of the ...
