    Infrared Laboratory Oscillator Strengths of Fe I in the H-band
    We report experimental oscillator strengths for 28 infrared Fe I transitions, for which no previous experimental values exist. These transitions were selected...

    Infrared Photometric Variability of GX 13+1 and GX 17+2
    We present infrared photometry of the Galactic bulge X-ray binary systems GX 13+1 and GX 17+2 obtained in 1997 July and August using OSIRIS on the 1.8 m Perkins...

    Infrared Photometry of Solar Photospheric Structures. I. Active Regions at the Center of the Disk
    Simultaneous time series of broadband images of two active regions close to the disk center were acquired at the Swedish Vacuum Solar Telescope, La Palma, in...

    Infrared Photometry of Solar Photospheric Structures. II. Center-to-Limb Variation of Active Regions
    Simultaneous broadband single images and time series of images have been obtained at λ0.8 and λ1.55 μm, which are at the extremes of the continuum absorption...

    Infrared Space Observatory Investigates the Nature of Extremely Red Hard X-Ray Sources Responsible for the X-Ray Background
    We analyze very deep X-ray and mid-IR surveys in common areas of the Lockman Hole and the Hubble Deep Field-North (HDF-N) to study the sources of the X-ray...

    Infrared Space Observatory Observations of IRAS 16594-4656: A New Proto-Planetary Nebula with a Strong 21 Micron Dust Feature
    Based on ISO short-wavelength spectrograph (SWS)+long-wavelength spectrograph (LWS) observations, IRAS 16594-4656 is identified as a new member of the rare...

    Infrared Study of Fullerene Planetary Nebulae
    We present a study of 16 planetary nebulae (PNe) where fullerenes have been detected in their Spitzer Space Telescope spectra. This large sample of objects...

    Insight into the Formation of the Milky Way Through Cold Halo Substructure. I. The ECHOS of Milky Way Formation
    We identify 10—seven for the first time—elements of cold halo substructure (ECHOS) in the volume within 17.5 kpc of the Sun in the inner halo of the Milky Way...

    Insight into the Formation of the Milky Way through Cold Halo Substructure. II. The Elemental Abundances of ECHOS
    We determine the average metallicities of the elements of cold halo substructure (ECHOS) that we previously identified in the inner halo of the Milky Way within...
