Fabry-Perot Images of Ionised and Molecular Hydrogen in Sgr A Academic Article

abstract

• Images of the central 36 arcseconds of the Galaxy in the Brackett gamma line of atomic hydrogen (2.17m) at a spatial resolution of 0.6 arcsec and a velocity resolution of 110 km/sec were obtained using UKIRT. The velocity separation between adjacent frames is 55 km/sec; 17 different velocities channels were imaged. Several distinct kinematic components are evident within the clumpy distribution of the ionised gas. An image in the v=1-0 S(1) line of molecular hydrogen (2.12m) clearly resolves the structure of the molecular ring.
