Gravity versus astrophysics in black hole images and photon rings: Equatorial emissions and spherically symmetric space-times
I. Urso, F. H. Vincent, M. Wielgus +2
The EHT collaboration released in 2019 the first horizon-scale images of a black hole accretion flow, opening a novel route for plasma physics comprehension and gravitational tests…
Polarized signatures of orbiting hot spots: special relativity impact and probe of spacetime curvature
F. H. Vincent, M. Wielgus, N. Aimar +2
[Abridged] Context. The Galactic Center supermassive black hole is well known to exhibit transient peaks of flux density on a daily basis across the spectrum. Recent infrared and m…
Magnetic reconnection plasmoid model for Sagittarius A* flares
N. Aimar, A. Dmytriiev, F. H. Vincent +4
Sagittarius A*, the supermassive black hole at the center of our galaxy, exhibits episodic near-infrared flares. The recent monitoring of three such events by the GRAVITY instrumen…
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…
