NGC1614. Nuclear star-formation or an X-ray weak AGN?
Abstract
NGC1614 is one of the most luminous galaxies in the nearby Universe. It an ongoing minor merger hosting an extremely bright star-forming circumnuclear ring (diameter 600 pc, SFR~40 M(sun)/yr). The nature of the nuclear (central 150 pc) activity is unclear, although, so far, there is no evidence of an AGN. Here we present new sub-arcsec mid-IR GTC/CanariCam imaging and spectroscopy of this object, which in combination with previous data, allowed us to constrain the properties of a possible AGN (or nuclear star- formation) as first step towards understanding the physical conditions and evolutionary state of the central kpc of NGC1614.
