    Stellar Disk Truncations at High z: Probing Inside-Out Galaxy Formation
    We have conducted a systematic search for stellar disk truncations in disklike galaxies at intermediate redshift (z
  • Publication
    Stellar Kinematics and Structural Properties of Virgo Cluster Dwarf Early-type Galaxies from the SMAKCED Project. I. Kinematically Decoupled Cores and Implications for Infallen Groups in Clusters
    We present evidence for kinematically decoupled cores (KDCs) in two dwarf early-type (dE) galaxies in the Virgo cluster, VCC 1183 and VCC 1453, studied as part...

    Stellar Kinematics and Structural Properties of Virgo Cluster Dwarf Early-type Galaxies from the SMAKCED Project. III. Angular Momentum and Constraints on Formation Scenarios
    We analyze the stellar kinematics of 39 dwarf early-type galaxies (dEs) in the Virgo Cluster. Based on the specific stellar angular momentum λRe and the...

    Stellar Kinematics in Double-Barred Galaxies: The σ-Hollows
    We present SAURON integral-field stellar velocity and velocity dispersion maps for four double-barred early-type galaxies: NGC 2859, NGC 3941, NGC 4725, and NGC...

    Stellar Multiplicity Meets Stellar Evolution and Metallicity: The APOGEE View
    We use the multi-epoch radial velocities acquired by the Apache Point Observatory Galactic Evolution Experiment (APOGEE) survey to perform a large-scale...

    Stellar Obliquities of Young Systems, Atmospheres Undergoing Contraction and Escape (SOYSAUCE): A Likely Aligned Orbit for the 3 Myr Planet TIDYE-1 b
    Despite the wide range of planet─star (mis)alignments in the mature population of transiting exoplanets, the small number of known young transiting planets are...

    Stellar Populations and Kinematics of Red Galaxies at z > 2: Implications for the Formation of Massive Galaxies
    We recently identified a substantial population of galaxies at z>2 with comparatively red rest-frame optical colors. These distant red galaxies (DRGs) are...

    Stellar Populations in the Outskirts of the Small Magellanic Cloud: No Outer Edge Yet
    We report the detection of intermediate-age and old stars belonging to the SMC at 6.5 kpc from the SMC center in the southern direction. We show, from the...

    Stellar Populations of Elliptical Galaxies in Virgo Cluster. I. The Data and Stellar Population Analysis
    We have determined spectroscopic ages of elliptical galaxies in the Virgo Cluster using spectra of very high signal-to-noise ratio (S/N>100 Å-1). We observed...
