Polarised Properties of Magnetised Accretion Onto Black Holes - Alejandra Jiménez-Rosales

Explore the polarised properties of magnetised accretion onto black holes in this 41-minute conference talk by Alejandra Jiménez-Rosales from the Kavli Institute for Theoretical Physics. Delve into the complexities of modeling low luminosity active galactic nuclei, such as Sagittarius A* and M87, using 3D General Relativistic Magnetohydrodynamic simulations and GR radiative transport calculations. Examine the challenges posed by collisionless plasma at event horizon scales, including nonthermal particle acceleration and two-temperature effects. Investigate the impact of initial conditions on horizon scale simulations and their consequences on resulting flows. Cover topics including spatially resolved polarization of M87/Sgr A*, infrared/X-ray flares in Sgr A*, particle heating in collisionless plasmas, black hole spin powered jets, and tests of General Relativity. Gain insights into magnetic field structure, linear polarization, the Gravity Collaboration's findings, forward modeling, and hotspot models. Conclude with a summary of current understanding and explore future observations, including helix motion and nonthermal particle acceleration in black hole accretion.
