NGC4388
High resolution spectroscopy with Resolve will enable us to perform unprecedented studies of the circumnuclear structure of AGN using the detailed velocity structure of the narrow Fe-Ka fluorescence line. Here we propose to observe NGC 4388, which exhibits the brightest narrow Fe-Ka emission line among Compton-thin Seyfert 2 galaxies. The bright narrow Fe-K line, Compton-thin absorption, and high inclination make it the best target for studying the ``torus'' and inner region. With Resolve, we can for the first time measure the detailed line profile itself, leading to unbiased determination of matter distribution profile around the nucleus.
