G-objects

The UCLA Galactic Center Group has been tracking specific stars orbiting the proposed black hole at the center of our Galaxy for 25 years using 2.2 micron images taken at Keck Telescopes on Mauna Kea in Hawaii. These stellar orbits, and a simple application of Kepler’s Laws of motion, provide the best evidence yet for a supermassive black hole, which has a mass 4 million times the mass of the Sun. Particularly important is the short period star S0-2, which has been observed for more than a full orbital period (orbital period ~ 16 years) and puts limits on how massive and far away the supermassive black hole is to Earth.

The center of our Galaxy hosts a supermassive black hole of 4 million times the mass of the Sun. A great number of stars spin around it at very high speed. The UCLA Galactic Center Group discovered another class of objects orbiting the black hole: the G objects. These peculiar objects look like gas clouds but behave like stars. G objects are likely stars that are hidden in a thick envelope of gas and dust. They may have formed as the result of the merger of a pair of stars. This animation is a visualization of the orbital motion of G objects and stars in the Galactic Center. The G objects are shown in magenta, young stars in green and old stars in orange. The orbits are based on the Keck data obtained between 1995 and 2019. The research is published in the journal Nature: https://www.nature.com/articles/s41586-019-1883-y.

Astronomers observed dust clouds lurking around the black hole at our galaxy’s center. They weren’t of that much interest, until they started behaving in unusual ways.
