Abstract

We investigate the physical properties of Fermi TeV BL Lac objects' jets by modelling the quasi-simultaneous spectral energy distribution of 29 Fermi TeV BL Lacs in the frame of a one-zone leptonic synchrotron self-Compton model. Our main results are the following. (i) There is a negative correlation between B and delta in our sample, which suggests that B and delta are dependent on each other mainly in the Thomson regime. (ii) There are negative correlations between nu(sy) and r, the nu(IC) and r, which is a signature of the energy-dependent statistical acceleration or the stochastic acceleration. There is a significant correlation between r and s, which suggests that the curvature of the electron energy distribution is attributed to the energy-dependent statistical acceleration mechanism. (iii) By assuming one proton per relativistic electron, we estimate the jet power and radiative power. A size relation P-e similar to P-p > P-r greater than or similar to P-B is found in our sample. The P-e > P-B suggests that the jets are particle dominated, and the P-e similar to P-p means that the mean energy of relativistic electrons approaches m(p)/m(e). There are not significant correlations between P-jet and black hole mass in high or low state with a subsample of 18 sources, which suggests that the jet power weakly depends on the black hole mass. (iv) There is a correlation between the changes in the flux density at 1 TeV and the changes in the gamma(peak), which suggests that the change/evolution of electron energy distribution may be mainly responsible for the flux variation.
