The geometry of the gas surrounding the Central Molecular Zone: on the origin of localised molecular clouds with extreme velocity dispersions

Mattia C. Sormani, Robin G. Tress, Simon C. O. Glover +6

Observations of molecular gas near the Galactic centre ($|l|<10^{\circ }$, $|b|<1^{\circ }$) reveal the presence of a distinct population of enigmatic compact clouds which are ch…
