    Indirect Evidence of an Active Radio Pulsar in the Quiescent State of the Transient Millisecond Pulsar SAX J1808.4-3658
    Millisecond radio pulsars are neutron stars that have been spun up by the transfer of angular momentum during the low-mass X-ray binary phase. The transition...

    Individual Estimates of the Virial Factor in 10 Quasars: Implications on the Kinematics of the Broad-line Region
    Assuming a gravitational origin for the Fe iiiλλ2039-2113 redshift and using microlensing based estimates of the size of the region emitting this feature, we...

    Inferring the 3D Shapes of Extremely Metal-poor Galaxies from Sets of Projected Shapes
    The three-dimensional (3D) shape of a galaxy inevitably is tied to how it has formed and evolved and to its dark matter halo. Local extremely metal-poor...

    Inflow of Gas to the Solar Neighborhood during Evolution of the Galactic Disk
    We discuss several lines of evidence indicating that gas is flowing into the solar neighborhood and go on to offer a theoretical framework to explain this...

    Influence of Atomic Polarization and Horizontal Illumination on the Stokes Profiles of the He I 10830 Å Multiplet
    The polarization observed in the spectral lines of the He I 10830 Å multiplet carries valuable information on the dynamical and magnetic properties of plasma...

    Influence of Thomson Electron Scattering Redistribution on Spectral Line Polarization Formed in Spherically Symmetric Extended and Expanding Atmospheres
    Scattering of line photons by ambient electrons in thermal motion in the stellar atmosphere modifies the wings of both intensity and linear polarization...

    Infrared and Kinematic Properties of the Substellar Object G 196-3 B
    We report unusual near- and mid-infrared photometric properties of G 196-3 B, the young substellar companion at 16'' from the active M2.5-type star G 196-3 A...

    Infrared Extinction in the Inner Milky Way through Red Clump Giants
    While the shape of the extinction curve in the infrared is considered to be set and the extinction ratios between infrared bands are usually taken to be...

    Infrared High-resolution Integrated Light Spectral Analyses of M31 Globular Clusters from APOGEE
    Chemical abundances are presented for 25 M31 globular clusters (GCs), based on moderately high resolution (R = 22,500) H-band integrated light (IL) spectra from...
