Title: The Active Nucleus in NGC 4579
Authors: Roberto B. Menezes, Joćo E. Steiner, Tiago V. Ricci, Alexandre S. Oliveira

In this work, we present an analysis of a data cube obtained with the instrument IFU/GMOS Gemini North telescope centred on the nuclear region of the LINER galaxy NGC 4579. This galaxy is known to have a type 1 AGN (see Eracleous et al. 2002 for a review). The methodology used for the analysis of the data cube was PCA tomography (Steiner et al. 2009), which consists of applying the statistical tool known as principal component analysis (PCA) to extract information from data cubes.
