Ordered magnetic fields around the 3C 84 central black hole

G. F. Paraschos, J. -Y. Kim, M. Wielgus +279

3C84 is a nearby radio source with a complex total intensity structure, showing linear polarisation and spectral patterns. A detailed investigation of the central engine region nec…

Characterization of black hole accretion through image moment invariants

A. Jiménez-Rosales, A. I. Yfantis, M. A. Mościbrodzka +1

We apply image moment invariant analysis to total intensity and polarimetric images calculated from general relativistic magnetohydrodynamic simulations of accreting black holes. W…

Comparison of Polarized Radiative Transfer Codes used by the EHT Collaboration

Cora Prather, Jason Dexter, Monika Moscibrodzka +270

Interpretation of resolved polarized images of black holes by the Event Horizon Telescope (EHT) requires predictions of the polarized emission observable by an Earth-based instrume…

Constraining particle acceleration in Sgr A* with simultaneous GRAVITY, Spitzer, NuSTAR and Chandra observations

R. Abuter, A. Amorim, M. Bauböck +81

We report the time-resolved spectral analysis of a bright near-infrared and moderate X-ray flare of Sgr A*. We obtained light curves in the -, -, and -bands in the mid- an…

The impact of Faraday effects on polarized black hole images of Sagittarius A*

Alejandra Jiménez-Rosales, Jason Dexter

We study model images and polarization maps of Sagittarius A* at 230 GHz. We post-process GRMHD simulations and perform a fully relativistic radiative transfer calculation of the e…
