Abstract (ScienceDirect, SAO/NASA ADS)
Tachyonic spectral densities of ultrarelativistic electron populations are fitted to the γray spectra of two microquasars, LS 5039 and LSI +61°303. The superluminal spectral maps are obtained from BATSE, COMPTEL, EGRET, HESS, and MAGIC data sets. The spectral averaging is done with exponentially cut powerlaw densities. Estimates of the electron distributions generating the tachyon flux are obtained from the spectral fits, such as powerlaw indices, electron temperature and source counts. The internal energy and heat capacities of the source populations are calculated. An extensive entropy functional is defined for Boltzmann powerlaw densities and its stability is checked. The hightemperature limit of the thermodynamic variables is determined by the powerlaw index of the electron plasma, which enters in the scaling exponents as well as the amplitudes.
