Flaremodel: An open-source Python package for one-zone numerical modelling of synchrotron sources
Y. Dallilar, S. von Fellenberg, M. Bauböck +13
Synchrotron processes, the radiative processes associated with the interaction of energetic charged particles with magnetic field, are of interest in many areas in astronomy, from…
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…
Relative depolarization of the black hole photon ring in GRMHD models of Sgr A* and M87*
A. Jiménez-Rosales, J. Dexter, S. M. Ressler +15
Using general relativistic magnetohydrodynamic simulations of accreting black holes, we show that a suitable subtraction of the linear polarization per pixel from total intensity i…
Sgr A* near-infrared flares from reconnection events in a magnetically arrested disc
J. Dexter, A. Tchekhovskoy, A. Jiménez-Rosales +14
Large-amplitude Sgr A* near-infrared flares result from energy injection into electrons near the black hole event horizon. Astrometry data show continuous rotation of the emission…
