    The Orbit and Origin of the Ultra-faint Dwarf Galaxy Segue 1
    We present the first proper motion measurement for an ultra-faint dwarf spheroidal galaxy, Segue 1, using data from the Sloan Digital Sky Survey (SDSS) and the...

    The Orientation of Disk Galaxies around Large Cosmic Voids
    Using a large sample of galaxies from the the seventh data release of the Sloan Digital Sky Survey (SDSS-DR7), we have analyzed the alignment of disk galaxies...

    The orientation of galaxy dark matter haloes around cosmic voids
    Using the Millennium N-body Simulation we explore how the shape and angular momentum of galaxy dark matter haloes surrounding the largest cosmological voids are...

    The orientation of WARPS in the Local Group.
    The three major spiral galaxies in the Local Group are known to be warped. The question is investigated of whether or not these three warps are aligned. Using...

    The origin of bulges and discs in the CALIFA survey - I. Morphological evolution
    This series of papers aims at understanding the formation and evolution of non-barred disc galaxies. We use the new spectro-photometric decomposition code, C2D...

    The origin of extended disc galaxies at z = 2
    Galaxy formation models typically assume that the size and rotation speed of galaxy discs are largely dictated by the mass, concentration and spin of their...

    The origin of stars in the inner 500 parsecs in TNG50 galaxies
    We investigate the origin of stars in the innermost 500 pc of galaxies spanning stellar masses of $5\times 10^{8-12}\, \mathrm{M}_{\odot }$ at z = 0 using the...

    The Origin of the 300 km s‑1 Stream near Segue 1
    We present a search for new members of the 300 km s‑1 stream (300S) near the dwarf galaxy Segue 1 using wide-field survey data. We identify 11 previously...
