Astronomers Use G1 and G2 to Probe the Accretion Flow Feeding Sgr A*

New research uses the G1 and G2 gas clouds to probe the accretion flow feeding Sgr A∗. The center of our Milky Way galaxy, about twenty-five thousand light years from Earth, is invisible to us in optical light because of the extensive amounts of absorbing, intervening dust. Radiation at many other wavelengths, however, including the […]
