[14.12] Near-Infrared Integral Field Spectroscopy of Normal Star-Forming Galaxies

The Palomar Integral Field Spectrograph was used to probe a variety of environments in nine nearby galaxies that span a range of morphological types, luminosities, and infrared-to-blue ratios. Near-infrared spectroscopy over two spatial dimensions was obtained for nuclear or bright extranuclear regions in the [FeII]~(1.257\micron), [FeII]~(1.644\micron), Pa\beta~(1.282\micron), H2~(2.122\micron), and Br\gamma~(2.166\micron) transition lines. These data yield constraints on various characteristics of the star-forming episodes in these regions, including their strength, maturity, spatial variability, and extinction.
