HIGH ANGULAR RESOLUTION BROAD-BAND IMAGING IN THE MIDINFRARED - THE INFRARED BRIGHT GALAXY NGC-34

We report on a high angular resolution (1") mid-IR image of the IR-bright galaxy NGC 34. The observation shows the mid-IR emission to be very compact, less-than-or-equal-to 2.3" x 1.7" (less-than-or-equal-to 870 x 640 pc, D = 78 Mpc, H0 = 75 km s-1 Mpc-1). This and previous observations indicate sizes smaller than predicted by starburst models for the emission. The achieved sensitivity, 15 mJy minutes-1/2 arcsec-2, (1-sigma NEFD DELTA-lambda = 5-mu-m) is the highest sensitivity ever obtained for any observation with a mid-IR array camera.
