    Two-dimensional Spectroscopy in the Circumnuclear Region of the Seyfert 1 Ring Galaxy NGC 985
    We present two-dimensional optical spectroscopy of the central region (9.4"x12.2") of the Seyfert 1 ring galaxy NGC 985 obtained with an optical fiber system...

    Tycho's Supernova: The View from Gaia
    SN 1572 (Tycho Brahe’s supernova) clearly belongs to the Ia (thermonuclear) type. It was produced by the explosion of a white dwarf (WD) in a binary system. Its...

    Ultra-deep Sub-kiloparsec View of nearby Massive Compact Galaxies
    Using Gemini North telescope ultra-deep and high-resolution (sub-kiloparsec) K-band adaptive optics imaging of a sample of four nearby (z ~ 0.15) massive (~1011...

    Ultra-red Galaxies Signpost Candidate Protoclusters at High Redshift
    We present images obtained with LABOCA of a sample of 22 galaxies selected via their red Herschel SPIRE colors. We aim to see if these luminous, rare, and...

    Ultra-short Period Binaries from the Catalina Surveys
    We investigate the properties of 367 ultra-short period binary candidates selected from 31,000 sources recently identified from Catalina Surveys data. Based on...

    Ultramassive Black Holes in the Most Massive Galaxies: M<SUB>BH</SUB>-σ versus M<SUB>BH</SUB>-R<SUB>b</SUB>
    We investigate the nature of the relations between black hole (BH) mass (M BH) and the central velocity dispersion (σ) and, for core-Sérsic galaxies, the size...

    Understanding the Cosmic Mass Function High-Mass Behavior
    We claim that the discrepancy found between the theoretical predictions for the cosmic mass function and those found in numerical simulations is due to the fact...

    Unraveling the Complexity of Dwarf Galaxy Dynamics: A Study of Binary Orbital Motions
    We investigate the impact of binary orbital motions on the dynamical modeling of dwarf galaxies with intrinsic line-of-sight velocity dispersions ( ${\sigma }_{...

    Unveiling the Active Nucleus of Centaurus A
    We report new Hubble Space Telescope WFPC2 and NICMOS observations of the center of the nearest radio galaxy Centaurus A (NGC 5128) and discuss their...
