    The Infrared Nuclear Emission of Seyfert Galaxies on Parsec Scales: Testing the Clumpy Torus Models
    We present subarcsecond resolution mid-infrared (mid-IR) photometry in the wavelength range from 8 to 20 μm of 18 Seyfert galaxies, reporting high spatial...

    The Infrared Spectral Energy Distribution of the Seyfert 2 Prototype NGC 5252
    The complete mid- to far-infrared continuum energy distribution collected with the Infrared Space Observatory of the Seyfert 2 prototype NGC 5252 is presented...

    The Inhomogeneous Surface of Centaur 32522 Thereus (2001 PT13)
    Eight low-resolution near-infrared spectra (0.8-2.4 μm) of 32522 Thereus were obtained on 2002 August 28 from 0:30 to 5:30 UT, covering more than half of its...

    The Initial Mass Function of Lens Galaxies from Quasar Microlensing
    We present a new approach to studying the initial mass function (IMF) in external galaxies based on quasar microlensing observations. We use measurements of...

    The Interaction of Asymptotic Giant Branch Stars with the Interstellar Medium
    We study the hydrodynamical behavior of the gas expelled by moving asymptotic giant branch stars interacting with the interstellar medium (ISM). Our models...

    The Intergalactic Stellar Population from Mergers of Elliptical Galaxies with Dark Matter Halos
    We present simulations of dry-merger encounters between pairs of elliptical galaxies with dark matter halos. The aim of these simulations is to study the...

    The Internal Proper Motion Kinematics of NGC 346: Past Formation and Future Evolution
    We investigate the internal kinematics of the young star-forming region NGC 346 in the Small Magellanic Cloud (SMC). We used two epochs of deep F555W and F814W...

    The Interstellar Medium in High-redshift Submillimeter Galaxies as Probed by Infrared Spectroscopy*
    Submillimeter galaxies (SMGs) at z≳ 1 are luminous in the far-infrared, and have star formation rates, SFR, of hundreds to thousands of solar masses per year...

    The Intriguing Stellar Populations in the Globular Clusters NGC 6388 and NGC 6441
    NGC 6388 and NGC 6441 are two massive Galactic bulge globular clusters that share many properties, including the presence of an extended horizontal branch (HB)...
