Sensitivity of the Fermi Detectors to Gamma-Ray Bursts from Evaporating Primordial Black Holes (PBHs) |
|
Abstract |
Primordial Black Holes (PBHs), which may have been created in the early Universe, are predicted to be detectable by their Hawking radiation. PBHs with an initial mass of ~ 5 x 10^14 g should be expiring today with a burst of high energy particles including gamma-rays. Evaporating PBHs are candidate progenitors of unidentified non-repeating Gamma-Ray Bursts (GRBs). We propose spectral lag, which is the temporal delay between the high and low energy pulses, as a possible method to identify PBH evaporation events with the Fermi Gamma-ray Space Telescope Observatory detectors. |
