    Radiation of microwaves and infrared by slender graphite needles
    (Kluwer Academic Publishers, 1984-03-22) Hoyle, F.; Narlikar, J. V.; Wickramasinghe, N. C.
    It has become clear from sources observed by IRAS that there are many examples which attain maximum emission per unit (frequency) bandwidth longward of 100 μm. Here, we show that a large emissivity at such long wavelengths can be obtained by needle-shaped particles of free carbon. Indeed for needles with a sufficiently high ratio of length to diameter the large emissivity extends from the infrared through the whole microwave region of the spectrum.

    On the behaviour of radiation near massive bodies
    (American Astronomical Society, 1964-04-04) Faulkner, J.; Hoyle, F.; Narlikar, J. V.
    The problem of communication between an observer on the surface of a massive body and an externa 1 Schwarzschild observer is examined. It is shown that when the body is freely imploding a signal from the external observer never reaches the surface provided the Schwarzschild coordinate of the external observer exceeds a critical value depending on the mass and radius of the body. The signals that reach the surface are redshifted. Time reversal of the solution then shows that radiation from an exploding massive body will be blueshifted when it reaches an external observer. This effect may supply the explanation for the origin of high-energy particles and quanta.

    Curriculum for the training of astronomers
    (Cambridge University Press, 1990-07-30) Narlikar, J. V.
    Teaching astronomy depends on deciding what to teach. In addition to a general discussion of desiderata, the papers in this section discuss particular programs in the U. K., China, Portugal, Hungary, and Brazil countries that are broadly representative of world astronomy. Some related papers appear in the chapter on the developing countries.
