  • We mapped the high-velocity compact cloud CO-0.40-0.22 in 21 molecular lines in the 3 mm band using the Nobeyama Radio Observatory 45 m radio telescope. Eighteen lines were detected from CO-0.40-0.22. The map of each detected line shows that this cloud has a compact appearance (d=~3 pc) and extremely broad velocity width (DV=~100 km/s). The mass and kinetic energy of CO-0.40-0.22 are estimated to be 10^{3.6} M_sun and 10^{49.7} erg, respectively. The representative position-velocity map along… CONTINUE READING
