Query: Hot Molecular Gas in the Central 10 Parsecs of the Galaxy   We present results from observations of NH_3(1,1), (2,2), (3,3), and (6,6)
with the Very Large Array. The data sample the inner 10 pc (4') of the Galaxy
and have a velocity coverage of -140 to +130 km/s. The velocity integrated
NH_3(3,3) image shows that the Sgr A East supernova remnant is impacting the 50
km/s GMC in the northeast, the northern ridge in the north, and the western
streamer in the west. These results imply that the Sgr A East has a large
effect on the molecular environment near Sgr A* and may be pushing much of the
molecular gas away from Sgr A*. The physical properties of the western streamer
and its relation to Sgr A East are discussed in detail. We also summarize the
detection of hot molecular gas less than 2 pc from Sgr A* in projected
distance. This gas is seen only in NH_3(6,6) and has line widths of 75-85 km/s,
indicating that it is physically close to the nucleus.
