Abstract (from CDS):

Sub-arcsec images in the J,H,K and H2 and nearby continuum of the bipolar outflow NGC 6334 I are presented. Three knots of H2 emission are found which coincide with recently discovered NH3(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 H2 emission knot and associated ammonia maser.
