Scientific paper

Near-IR observations of the starburst galaxy NGC 253 using a large-format array and high spatial sampling show four knots of enhanced emission (hot spots) in the nuclear region. Each hot spot may correspond spatially to a compact radio knot. Several possible origins of these hot spots are discussed and suggestions are given for observational tests of the possibilities.
