    Cosmic microwave background spectrum in the Hoyle-Narlikar cosmology
    (Elsevier Science Publishers, 1983-11-21) Narlikar, J. V.; Rana, N. C.
    It is shown that the theoretical curve of relic radiation in the G-varying Hoyle-Narlikar cosmology provides an accep- table fit to the observations at long as well as short wavelengths.

    Cosmic microwave background spectrum and G-varying cosmology
    (Elsevier Science Publishers, 1980-03-19) Narlikar, J. V.; Rana, N. C.
    It is shown that G-varying cosmologies provide a better fit to the observed data on cosmic microwave background, than the standard Friedmann models.

    Hawking process and the cosmic microwave background in a steady state universe
    (Elsevier, 1979-06-25) Narlikar, J. V.; Rana, N. C.
    It is investigated whether a large number of primordial black holes can account for the observed microwave background in a steady state universe.The answer is shown to be negative.

    Education in astronomy and astrophysics: the Indian experience
    (Elsevier Science Publishers, 1997-08-22) Narlikar, J. V.; Rana, N. C.
    In the context of a vast region with one-sixth of the global population, the Indian subcontinent has a very rich tradition of teaching of astronomy as a science. The so called modern astronomy has mostly been developed over the past two centuries whereas the subject of astrophysics is barely a hundred years old. This work reviews briefly the current efforts in India in propagating these subjects not only at the research level but all the way down to the level of school children. With the creation of IUCAA, these efforts have been systematized and the response to them has been very rewarding.
