    An Imperfectly Passive Nature: Bright Submillimeter Emission from Dust-obscured Star Formation in the z = 3.717 “Passive” System, ZF 20115
    The identification of high-redshift, massive galaxies with old stellar populations may pose challenges to some models of galaxy formation. However, to securely...

    An improved method for statistical studies of the internal kinematics of HII regions: the case of M83
    We present the integrated Hα emission line profile for 157 HII regions in the central 3.4 × 3.4 arcmin2 of the galaxy M83 (NGC 5236). Using the Fabry-Perot...

    An Infrared Census of DUST in Nearby Galaxies with Spitzer (DUSTiNGS). IV. Discovery of High-redshift AGB Analogs
    The survey for DUST in Nearby Galaxies with Spitzer (DUSTiNGS) identified several candidate Asymptotic Giant Branch (AGB) stars in nearby dwarf galaxies and...

    An infrared view of AGN feedback in a type-2 quasar: the case of the Teacup galaxy
    We present near-infrared integral field spectroscopy data obtained with Very Large Telescope/Spectrograph for INtegral Field Observations in the Near Infrared...

    An intermittent extreme BL Lac: MWL study of 1ES 2344+514 in an enhanced state
    Extreme high-frequency BL Lacs (EHBL) feature their synchrotron peak of the broad-band spectral energy distribution (SED) at ν s ≥ 10 17 Hz. The BL Lac object...

    An Investigation into the Prominence of Spiral Galaxy Bulges
    From a diameter-limited sample of 86 low-inclination (face-on) spiral galaxies, the bulge-to-disk size and luminosity ratios and other quantitative measurements...

    An ionized superbubble powered by a protocluster at z = 6.5
    We show herein that a proto-cluster of Ly α emitting galaxies, spectroscopically confirmed at redshift 6.5, produces a remarkable number of ionizing continuum...

    An old, metal-poor globular cluster in Sextans A and the metallicity floor of globular cluster systems
    We report the confirmation of an old, metal-poor globular cluster (GC) in the nearby dwarf irregular galaxy Sextans A, the first GC known in this galaxy. The...
