多くの銀河の中心には、質量が太陽の一千万倍を超える巨大ブラックホールがあると考えられていますが、確実な証拠はこれまでつかむことができませんでした。このたびVLBI観測によって中心天体のまわりの小さな領域で高速に回転するガスや星のすがたがとらえられました。この回転が太陽系の惑星のようなケプラー運動なら、中心天体の質量は簡単に算出できます。NGC4258(M106) という銀河系の中心近くのガス回転運動の様子をVLBI観測等によって調べたところ、半径0.13 パーセクより小さい領域に太陽の3600万倍の質量が存在することがわかりました。平均密度はこれまでブラックホールの候補と考えられてきた天体の40倍と大きく、NGC4258の中心にブラックホールが存在する有力な証拠と考えられています。

Figure 1: NRAO Very Large Array image of the radio galaxy 3C 403 at a wavelength of 3.6 cm. The intensity range of the colors (in Jansky, Jy, units) is indicated at the right hand side. The red arrow points at the galaxy's nucleus. The spectrum shown in the upper left hand inset was taken with the Effelsberg 100m telescope. The y-axis is flux density in Jy, while the x-axis gives the recession velocity (in km/s), i.e. the speed which with 3C 403 and the Milky Way are moving apart. The green arrow points at the systemic radial velocity of the whole galaxy. Image: National Radio Astronomy Observatory/Rick Perley (NRAO/AUI/NSF)
