Scientific paper

We have imaged the central regions of eight luminous infrared galaxies at 3.4 microns. In most cases complementary images at J (1.25 micron), H (1.65 micron), and K (2.2 microns) were obtained. The nuclei of all eight sources were detected at 3.4 microns. Several of the galaxies in our sample show significantly smaller image sizes at 3.4 microns than at K. We attribute these differences either to the presence of a compact infrared nucleus or to color differences among multiple nuclei. A very red compact infrared source is detected at the location of the radio source C-double prime in Arp 299.
