The Minispiral in the Galactic Center revisited.

VOLLMER B. and DUSCHL W.J.

Abstract (from CDS):

We present the results of a re-examination of a [Ne II] line emission data cube (lambda 12.8mu-m) and discuss the kinematic structure of the inner ∼ 3 x 4 pc of the Galaxy. The quality of [Ne II] as a tracer of ionized gas is examined by comparing it to radio data. A three-dimensional representation of the data cube allows us to disentangle features which are projected onto the same location on the sky. A model of gas streams in different planes is fitted to the data. We find that most of the material is located in a main plane which itself is defined by the inner edge of the Circum-Nuclear Disk in the Galactic Center. Finally, we present a possible three-dimensional model of the gas streams.
