UNDERSTANDING TURBULENCE-POWERED BLAZAR EMISSION

BLAZARS ACTIVE GALACTIC NUCLEI LAUNCHING A JET DIRECTED TOWARDS THE EARTH OFFER A UNIQUE OPPORTUNITY TO STUDY THE RADIATION PRODUCED IN EXTREME ASTROPHYSICAL ENVIRONMENTS. MODELING OF THE SPECTRAL ENERGY DISTRIBUTION (SED) OF BLAZARS HAS THE POTENTIAL TO PROVIDE INVALUABLE INSIGHTS ON THE PHYSICAL PROPERTIES OF RELATIVISTIC JETS. HOWEVER DESPITE THE ENORMOUS OBSERVATIONAL PROGRESS OUR CURRENT UNDERSTANDING IS LIMITED BY THE USE OF AD HOC ASSUMPTIONS FOR THE PARTICLE MOMENTUM DISTRIBUTION IN THE EMISSION REGION. WE WILL MODEL THE PARTICLE MOMENTUM DISTRIBUTION FROM FIRST PRINCIPLES USING FULLY KINETIC LARGE SCALE SIMULATIONS OF MAGNETIZED TURBULENT PLASMAS. WE WILL ADDRESS THE FAR-REACHING IMPLICATIONS OF THE FACT THAT PARTICLES ENERGIZED BY TURBULENCE ARE STRONGLY ANISOTROPIC.
