Paper: OH and H_2O Maser Distribution in Orion KL

Abstract: In order to study the powering source behind KL nebula, we made a map of OH and H_2O masers from VLA observations of this region, and compared their spatial distribution and velocity structure with that of the SiO masers. The distribution of the OH masers consists of a multi-stream structure and seems to be related to the Hot Core molecular emission. The low velocity H_2O masers may be classified as two groups: i) an inner clump of maser spots surrounding the SiO maser disc and continuum source ``I'', and ii) component associated with the Hot Core represented by HDO emission peaks.
