We present preliminary results of an HST/NICMOS program to image
merger remnants in the J, H and K bands. The nuclear brightness
profiles for most sample galaxies are similar to those typical for
elliptical galaxies, but some (including the well-studied NGC 3921 and
7252) have an unusually high luminosity density at small radii. This
is consistent with the prediction of N-body simulations that gas flows
to the center during a merger and forms new stars.
