School of Physics & Astronomy The relativistic viscous fluid equations describing the outflow of high temperature matter created via Hawking radiation from microscopic black holes are solved numerically for a realistic equation of state. We focus on black holes with initial temperatures greater than 100 GeV and lifetimes less than 6 days. The spectra of direct photons and photons from neutral pion decay are calculated for energies greater than 1 GeV. We calculate the diffuse gamma ray spectrum from black holes distributed in our galactic halo. However, the most promising route for the observation of exploding miscroscopic black holes is to search for point sources emitting gamma rays of ever-increasing energy. We are also calculating high energy neutrinos emitted directly and from pion or muon decays. Most of the initial mass of these black holes eventually ends up in photons and neutrinos.
