Ott et al. (2014) present a large-scale,
interferometric survey of ammonia toward the Galactic center observed with the
Australia Telescope Compact Array (ATCA). The survey covers the region between
the supermassive black hole Sgr A* and the massive star forming region Sgr B2
with a resolution of about 20 arcsec (0.8 pc). Emission at scales larger than
2 arcmin (3.2 pc) is filtered out due to missing short spacings. Consequently,
the data represent the denser, compact clouds and disregard the large-scale,
diffuse gas. - The RGB image shows the temperature map of the Galactic center:
Tkin ~ 30 K (blue), Tkin ~ 50 K (green), lower limit of
80 K (red). Radio continuum emission at 22 GHz (1 cm; white contours) is
overlaid in the bottom panel.
