We report the detection of two elongated X-ray features, G359.89-0.08 and G359.54+0.18, in the Galactic center (GC) region using the Chandra X-Ray Observatory. G359.89-0.08 is an elongated X-ray feature located ~2' in projection south of the center of the Galaxy, Sgr A*. This X-ray feature source is partially coincident with a slightly curved ("wisplike") nonthermal radio source. The X-ray spectrum of G359.89-0.08 can best be characterized as nonthermal, with a photon index of 2. The morphological and spectral characteristics of the X-ray and radio emission associated with G359.89-0.08 are best interpreted as the synchrotron emission from a ram pressure–confined …
