Stimulated Black Hole Evaporation


الملخص بالإنكليزية

Black holes are extreme expressions of gravity. Their existence is predicted by Einsteins theory of general relativity and is supported by observations. Black holes obey quantum mechanics and evaporate spontaneously. Here it is shown that a mass rate $R_fsim 3times 10^{-8} (M_0/M)^{1/2}$ $M_0$ yr$^{-1}$ onto the horizon of a black hole with mass $M$ (in units of solar mass $M_0$) stimulates a black hole into rapid evaporation. Specifically, $sim 3 M_0$ black holes can emit a large fraction of their mass, and explode, in $M/R_f sim 3times 10^7 (M/M_0)^{3/2}$ yr. These stimulated black holes radiate a spectral line power $P sim 2times 10^{39} (M_0/M)^{1/2}$ erg s$^{-1}$, at a wavelength $lambda sim 3times 10^5 (M/M_0)$ cm. This prediction can be observationally verified.
