NGC 5850 is a nearby (z=0.0085) early type spiral galaxy classified as LINER. It is considered as a prototype double-barred system. Our optical Integral Field Spectroscopic (IFS) data of the central 21x19 arcsec² of NGC 5850 show extended LINER-like emission which we ascribe to the presence of a hot and evolved stellar population, possibly together with a faint AGN. Additionally NGC 5850 shows extended `composite' ionisation patterns, likely to stem from a mixture of LINER-like ionisation and photoionisation by star formation. The kinematics of the gas deviates strongly from a simple rotational structure.

Title: Optical Integral Field Spectroscopy of NGC 5850
Authors: M. Bremer, J. Scharwächter, A. Eckart, J. Zuther, S. Fischer, M. Valencia-S

Here we present the preliminary results of the analysis of VIMOS observations of the central 4.5 kpc of the double-barred galaxy NGC 5850. We use optical diagnostic diagrams to study the main ionisation mechanism across the field of view confirming the LINER nature in the continuum peak location. Also a star-forming (SF) region is found close to it (0.46 kpc), a second SF region is located east of the center (1.6 kpc). Further the data reveals a complex nuclear gas kinematics which is likely to be dominated by the secondary bar.
