  • The Kinematics and X-ray Emission Mechanism of the Large-Scale Jet of 3C 111 

    Clautice, Devon (2016-12)
    Relativistic jets are the most energetic manifestation of the active galactic nucleus (AGN) phenomenon. AGN jets are observed from the radio through gamma rays and carry copious amounts of matter and energy from the ...

    One aspect of the quantum nature of spacetime is its “foaminess” at very small scales. Many models for spacetime foam are defined by the accumulation power α, which parameterizes the rate at which Planck-scale ...
