Item Massive oscillators as cosmic energy sources(Kluwer Academic Publishers, 1982-01-18) Apparao, K. M. V.; Narlikar, J. V.The usual picture in which a massive object undergoes a gravitational collapse to become a black hole and ultimately end up in space-time singularity, is modified with the introduction of a negative energy force of repulsion effective only at a short range. It is shown that the object executes oscullations between states of high and low densities. From the view point of high energy astrophysics, such a massive oscillator combines some of the attractive features of black holes and white holes. It is suggested that the energy production and spectral features of quasars, BL-Lacs and the active galactic nuclei might be accounted for by postulating the existence of massive oscillators.
