• Dwarfs Gobbling Dwarfs: A Stellar Tidal Stream Around NGC 4449 and Hierarchical Galaxy Formation on Small Scales 

      Martinez-Delgado, David; Romanowsky, Aaron J.; Gabany, R. Jay; Annibali, Francesca; Arnold, Jacob A.; Fliri, Jurgen; Zibetti, Stefano; van der Marel, Roeland P.; Rix, Hans-Walter; Chonis, Taylor S.; Carballo-Bello, Julio A.; Aloisi, Alessandra; Maccio, Andrea V.; Gallego-Laborda, J.; Brodie, Jean P.; Merrifield, Michael R. (2012-04)
      A candidate diffuse stellar substructure was previously reported in the halo of the nearby dwarf starburst galaxy NGC 4449 by Karachentsev et al. We map and analyze this feature using a unique combination of deep ...
    • A Petal Of The Sunflower: Photometry Of The Stellar Tidal Stream In The Halo Of Messier 63 (NGC 5055) 

      Chonis, Taylor S.; Martinez-Delgado, David; Gabany, R. Jay; Majewski, Steven R.; Hill, Gary J.; Gralak, Ray; Trujillo, Ignacio (2011-11)
      We present deep surface photometry of a very faint, giant arc-loop feature in the halo of the nearby spiral galaxy NGC 5055 (M63) that is consistent with being a part of a stellar stream resulting from the disruption of a ...
    • Stellar Tidal Streams In Spiral Galaxies Of The Local Volume: A Pilot Survey With Modest Aperture Telescopes 

      Martinez-Delgado, David; Gabany, R. Jay; Crawford, Ken; Zibetti, Stefano; Majewski, Steven R.; Rix, Hans-Walter; Fliri, Jurgen; Carballo-Bello, Julio A.; Bardalez-Gagliuffi, Daniella C.; Penarrubia, Jorge; Chonis, Taylor S.; Madore, Barry; Trujillo, Ignacio; Schirmer, Mischa; McDavid, David A. (2010-10)
      Within the hierarchical framework for galaxy formation, minor merging and tidal interactions are expected to shape all large galaxies to the present day. As a consequence, most seemingly normal disk galaxies should be ...
