Equipartition Gamma-Ray Blazars and the Location of the Gamma-Ray Emission Site in 3C 279

Understand

Blazar spectral models generally have numerous unconstrained parameters, leading to ambiguous values for physical properties like Doppler factor delta or fluid magnetic field B'.

• To help remedy this problem, a few modifications of the standard leptonic blazar jet scenario are considered.
• First, a log-parabola function for the electron distribution is used.
• Second, analytic expressions relating energy loss and kinematics to blazar luminosity and variability, written in terms of equipartition parameters, imply delta, B', and the principal electron Lorentz factor gamma'_pk.
