Spacetime Tomography Using The Event Horizon Telescope

Understand

We have now entered the new era of high-resolution imaging astronomy with the beginning of the Event Horizon Telescope (EHT).

• The EHT can resolve the dynamics of matter in the immediate vicinity around black holes at and below the horizon scale.
• One of the candidate black holes, Sagittarius A* flares 1\-4 times a day depending on the wavelength.
• A possible interpretation of these flares could be hotspots generated through magnetic reconnection events in the accretion flow.
