We present a high-resolution , multi-wavelength study of the massive protostellar cluster NGC 6334 I ( N ) that combines new spectral line data from the Submillimeter Array ( SMA ) and VLA with a reanalysis of archival VLA continuum data , 2MASS and Spitzer images . As shown previously , the brightest 1.3 mm source SMA1 contains substructure at subarcsecond resolution , and we report the first detection of SMA1b at 3.6 cm along with a new spatial component at 7 mm ( SMA1d ) . We find SMA1 ( aggregate of sources a , b , c , and d ) and SMA4 to be comprised of free-free and dust components , while SMA6 shows only dust emission . Our 1 \farcs 5 resolution 1.3 mm molecular line images reveal substantial hot-core line emission toward SMA1 and to a lesser degree SMA2 . We find CH _ { 3 } OH rotation temperatures of 165 \pm 9 K and 145 \pm 12 K for SMA1 and SMA2 , respectively . We estimate a diameter of 1400 AU for the SMA1 hot core emission , encompassing both SMA1b and SMA1d , and speculate that these sources comprise a \gtrsim 800 AU separation binary that may explain the previously-suggested precession of the outflow emanating from the SMA1 region . Compact line emission from SMA4 is weak , and none is seen toward SMA6 . The LSR velocities of SMA1 , SMA2 , and SMA4 all differ by 1-2 km s ^ { -1 } . Outflow activity from SMA1 , SMA2 , SMA4 , and SMA6 is observed in several molecules including SiO ( 5–4 ) and IRAC 4.5 ~ { } \mu m emission ; 24 \mu m emission from SMA4 is also detected . Eleven water maser groups are detected , eight of which coincide with SMA1 , SMA2 , SMA4 , and SMA6 , while two others are associated with the Sandell et al . ( 2000 ) source SM2 . We also detect a total of 83 Class I CH _ { 3 } OH 44 GHz maser spots which likely result from the combined activity of many outflows . Our observations paint the portrait of multiple young hot cores in a protocluster prior to the stage where its members become visible in the near-infrared .
