HCN−0.009−0.044
HCN−0.009−0.044 is an interstellar gas cloud near the centre of the Milky Way. The cloud is only 25 light-years from Sagittarius A*. It likely hosts an intermediate-mass black hole with a mass of 32,000 times that of the Sun. HCN−0.009−0.044 has a diameter of about 3 light years, and has relative gas movements of 40 km/s, with a kinematic energy of over 1047 ergs. The HCN in the name indicates the presence of hydrogen cyanide. HCN radiation at 354.6 GHz in the submillimeter was detected from the cloud.
