However, this central region is veiled by large amounts of dust, and it has been so far unclear which is the true dynamical nucleus. The near infrared spectroscopy could be advantageous in order to shed light on the true nucleus identity. Using Flamingos-2 at Gemini South we have taken deep K-band spectra along the major axis and through the brightest infrared source. We present evidence showing that the brightest near infrared and mid infr","authors_text":"G. Bosch, G.I. G\\\"unthardt, J.A. Camperi, M.P. Ag\\\"uero, M. Schirmer, P.L. Gomez, R.J.
