    Shadows in the Dark: Low-surface-brightness Galaxies Discovered in the Dark Energy Survey
    We present a catalog of 23,790 extended low-surface-brightness galaxies (LSBGs) identified in $\sim 5000\,{\deg }^{2}$ from the first three years of imaging...

    The Importance of Having an Extended Point-spread Function in Low Surface-brightness Science
    Obtaining and characterizing the extended point-spread function (PSF) is essential to extract accurate photometric information from deep imaging surveys. In...

    The Undiscovered Ultradiffuse Galaxies of the Local Group
    Ultradiffuse galaxies (UDGs) are attractive candidates to probe cosmological models and test theories of galaxy formation at low masses; however, they are...

    Young, Blue, and Isolated Stellar Systems in the Virgo Cluster. II. A New Class of Stellar System
    We discuss five blue stellar systems in the direction of the Virgo cluster, analogous to the enigmatic object SECCO 1 (AGC 226067). These objects were...
