摘要：

Near-infrared 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. We find that each hot spot may correspond spatially to a compact radio knot. We discuss several possible origins of these hot spots and suggest observational tests of the possibilities.
