Constraining the Accretion Flow in Sgr A* by GR Dynamical and Radiative Modeling

Shcherbakov, Roman V., Penna, Robert F.

Understand

We present the combination of dynamical accretion model based on 3D GRMHD simulations and general relativistic (GR) polarized radiative transfer.

  • We write down the formalism of and perform the GR ray-tracing of cyclo-synchrotron radiation through the model of accretion flow in Sagittarius A*.
  • GR polarimetric imaging is presented as well as the results for spectrum for a probable set of spins and orientations.
  • Precise fitting formulae for Faraday rotation and Faraday conversion coefficients are employed for thermal plasma.
