Shocked molecular hydrogen emission in the bipolar outflow NGC 6334 I.
Abstract
Sub-arcsec images in the J,H,K and H_2_ and nearby continuum of the bipolar outflow NGC 6334 I are presented. Three knots of H_2_ emission are found which coincide with recently discovered NH_3_(3,3) masers. Two of these are aligned along the CO bipolar outflow, indicating that the hydrogen molecular emission is shock excited. We have also detected a loop-shaped infrared nebula extending to the east of the massive mid-infrared source IRS1 which illuminates the reflection nebula. IRS1 consists of at least four components in the near-infrared. The interaction of the stellar wind from these young stellar objects with the surrounding medium could excite the third H_2_ emission knot and associated ammonia maser.
