Title: Near-Infrared Integral Field Spectroscopy of an AGN Pair in a Nearby Spiral Galaxy
Abstract:
High spatial resolution Chandra X-ray image has recently revealed that the
central region of the Seyfert 2 galaxy NGC 3393 contains a close pair of
obscured AGNs. However, the host galaxy does not exhibit the disrupted
morphology and vigorous star formation seen in NGC 6240, another double AGN.
NGC 3393 therefore resembles a merging scenario with a smaller companion -
the minor merger evolution that has long been sought for. We propose to
perform spatially resolved, integral field K-band spectroscopic observations
of NGC 3393 with Gemini+NIFS and the laser guide star system. We will measure
the relative velocities and masses of the two nuclei, and the gas/stellar
dynamics in this rare and important merging system, which will provide clues
on the geometry and stage of the merger process.
