Synchrotron-limited Particle Acceleration in Relativistic Shearing Flows

Frank M. Rieger, Peter Duffy

Fermi-type shear particle acceleration is a promising mechanism for sustaining ultra-relativistic particles along the kilo-parsec scale jets in Active Galactic Nuclei (AGNs). We ex…

Particle Acceleration in Relativistic Shearing Flows: Energy Spectrum

Frank M. Rieger, Peter Duffy

We consider the acceleration of charged particles in relativistic shearing flows, with Lorentz factor up to . We present numerical solutions to the particle transport…

Progenitor, environment, and modelling of the interacting transient, AT 2016jbu (Gaia16cfr)

S. J. Brennan, M. Fraser, J. Johansson +67

We present the bolometric lightcurve, identification and analysis of the progenitor candidate, and preliminary modelling of AT2016jbu (Gaia16cfr). We find a progenitor consistent w…

Photometric and spectroscopic evolution of the interacting transient AT 2016jbu (Gaia16cfr)

S. J. Brennan, M. Fraser, J. Johansson +68

We present the results from a high cadence, multi-wavelength observation campaign of AT 2016jbu (aka Gaia16cfr), an interacting transient. This dataset complements the current lite…

Turbulence and Particle Acceleration in Shearing Flows

Frank M. Rieger, Peter Duffy

We explore constraints imposed by shear-driven instabilities on the acceleration of energetic particles in relativistic shearing flows. We show that shearing layers in large-scale…

Particle Acceleration in Shearing Flows: Efficiencies and Limits

Frank M. Rieger, Peter Duffy

We examine limits to the efficiency for particles acceleration in shearing flows, showing that relativistic flow speeds are required for efficient gradual shear acceleration. We es…
