A pilot survey of stellar tidal streams in nearby spiral galaxies
David Martinez-Delgado, R. Jay Gabany, Jorge Penarrubia +4
Within the hierarchical framework for galaxy formation, merging and tidal interactions are expected to shape large galaxies to this day. While major mergers are quite rare at prese…
The Seventh Data Release of the Sloan Digital Sky Survey
K. Abazajian
This paper describes the Seventh Data Release of the Sloan Digital Sky Survey (SDSS), marking the completion of the original goals of the SDSS and the end of the phase known as SDS…
The ghost of a dwarf galaxy: fossils of the hierarchical formation of the nearby spiral galaxy NGC 5907
David Martinez-Delgado, Jorge Penarrubia, R. Jay Gabany +3
We present an extragalactic perspective of an extended stellar tidal stream wrapping around the edge-on, spiral galaxy NGC 5907. Our deep images reveal for the first time a large s…
Discovery of a Giant Stellar Tidal Stream Around the Disk Galaxy NGC 4013
David Martinez-Delgado, Michael Pohlen, R. Jay Gabany +3
We report the discovery of a giant, loop-like stellar structure around the edge-on spiral galaxy NGC 4013. This arcing feature extends 6 arcmin (~26 kpc in projected distance) nort…
