    Cold, Supersonic Evershed Downflows in a Sunspot
    We report here on the discovery of supersonic Evershed downflows in the penumbra of a sunspot. These flows are shown to occur along spatially unresolved, very...

    COLDz: A High Space Density of Massive Dusty Starburst Galaxies ∼1 Billion Years after the Big Bang
    We report the detection of CO(J = 2 → 1) emission from three massive dusty starburst galaxies at z > 5 through molecular line scans in the NSF's Karl G. Jansky...

    Color Profiles of Disk Galaxies since z ~ 1: Probing Outer Disk Formation Scenarios
    We present deep color profiles for a sample of 415 disk galaxies within the redshift range 0.1

    Color Profiles of Spiral Galaxies: Clues on Outer-Disk Formation Scenarios
    We have explored radial color and stellar surface mass density profiles for a sample of 85 late-type spiral galaxies with deep (down to ~27 mag arcsec-2) SDSS g...

    Color Transformations and Bolometric Corrections for Galactic Halo Stars: α-Enhanced versus Scaled-Solar Results
    We have performed the first extensive analysis of the impact of an [α/Fe]>0 metal distribution on broadband colors in the parameter space (surface gravity...

    Compact Optical Counterparts of Ultraluminous X-Ray Sources
    Using archival Hubble Space Telescope (HST) imaging data, we report the multiband photometric properties of 13 ultraluminous X-ray sources (ULXs) that have a...

    Company for the Ultra-high Density, Ultra-short Period Sub-Earth GJ 367 b: Discovery of Two Additional Low-mass Planets at 11.5 and 34 Days
    GJ 367 is a bright (V ≈ 10.2) M1 V star that has been recently found to host a transiting ultra-short period sub-Earth on a 7.7 hr orbit. With the aim of...

    Comparing M31 and Milky Way Satellites: The Extended Star Formation Histories of Andromeda II and Andromeda XVI
    We present the first comparison between the lifetime star formation histories (SFHs) of M31 and Milky Way (MW) satellites. Using the Advanced Camera for Surveys...

    Comparing Observed with Simulated Solar-disk-center Scattering Polarization in the Sr I 4607 Å Line
    Solar magnetic fields alter scattering polarization in spectral lines like Sr I at 4607 Å via the Hanle effect, making it a potential diagnostic for small-scale...
