Examining the supermassive black hole in our galaxy
The supermassive black hole (SMBH) at our galaxy's core, Sagittarius A*, is modest in size with only 4.15 million solar-masses
The Event Horizon Telescope (EHT) recently released a dramatic submillimeter image of it as seen illuminated by its glowing environment.
As gas and dust slowly accrete onto a black hole's surrounding hot, disk-like environment they radiate across the electromagnetic spectrum

The scientists consider three scenarios: the infrared and X-ray emission in these flares arose from charged particles spiraling in powerful magnetic fields;
the X-ray emission was produced when infrared photons collided with charged particles moving near the speed of light;
one consistent picture in which the infrared and X-rays originate via the second process
