    Spider-webb: Spatially Resolved Evidence of Inside-out Quenching in the Spiderweb Protocluster at z ∼ 2
    We present a spatially resolved analysis of galaxy quenching within the Spiderweb Protocluster at z ∼ 2.16, combining deep imaging from the James Webb Space...

    Spinning up the Surface: Evidence for Planetary Engulfment or Unexpected Angular Momentum Transport?
    In this paper, we report the potential detection of a nonmonotonic radial rotation profile in a low-mass lower-luminosity giant star. For most low- and...

    Spitzer Microlensing of MOA-2016-BLG-231L: A Counter-rotating Brown Dwarf Binary in the Galactic Disk
    We analyze the binary microlensing event MOA-2016-BLG-231, which was observed from the ground and from Spitzer. The lens is composed of very-low-mass brown...

    Spitzer Mid-IR Spectroscopy of Powerful 2 Jy and 3CRR Radio Galaxies. I. Evidence against a Strong Starburst-AGN Connection in Radio-loud AGN
    We present deep Spitzer/Infrared Spectrograph (IRS) spectra for complete samples of 46 2 Jy radio galaxies (0.05 z 0.7) and 19 3CRR FRII radio galaxies (z 0...

    Spitzer Reveals Infrared Optically Thin Synchrotron Emission from the Compact Jet of the Neutron Star X-Ray Binary 4U 0614+091
    Spitzer observations of the neutron star (ultracompact) X-ray binary (XRB) 4U 0614+091 with the Infrared Array Camera reveal emission of nonthermal origin in...
