My work involves developing and applying a physically motivated multi-zone jet model to a variety of low luminosity active galactic nuclei, fitting their radio to X-ray spectral energy distributions to constrain and better understand micro/macro jet physics and particle acceleration, and how it might vary between sources. Building on this, a new analysis pipeline is being developed that...
A key open question in astrophysics is how particles are heated and accelerated in accretion flows and how this shapes observed emission. We present a new method for reconstructing the connection between plasma dynamics and particle acceleration in the accretion flow of the LLAGN M87*, using the 2017 Event Horizon Telescope multi-wavelength campaign as a prototype. Our Bayesian framework...
The super-fast (~day), very-high-energy (VHE; >0.1 TeV) photon flares from the nearby active galactic nucleus M87 provide a unique, exciting opportunity to fast-forward our understanding of particle acceleration in jets. Despite 5 detected VHE flares in the last 20 years and extensive multiwavelength (MWL) campaigns, the process and location of these VHE flares in the jet are still not fully...
We investigate the composition and dynamics of black hole accretion jets using novel high-res GRMHD simulations. By deploying Lagrangian composition tracers and adaptive mesh refinement (AMR), we achieve two goals: 1) We precisely track how disk material mixes into the jet and how jet plasma entrains into the surrounding sheath, and 2) We maintain high resolution dynamically within the jet and...
I will review several energy extraction mechanisms (classical and quantum) to facilitate discussions on approaching the Blandford-Znajek process in the future.
