We present spatially resolved integral field spectroscopic K-band data at a resolution of 0.13" (60 pc) and interferometric CO(2-1) line observations of the prototypical merging system NGC 6240. Despite the clear rotational signature, the stellar kinematics in the two nuclei are dominated by dispersion. We use Jeans modelling to derive the masses and the mass-to-light ratios of the nuclei. Combining the luminosities with the spatially resolved Brγ equivalent width shows that only 1/3 of the...[Show more]
