An External Perspective of a Stellar Tidal Stream: Fossils of the Hierarchical Formation of the Nearby Spiral Galaxy NGC~5907
We present with outstanding detail 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 scale complex of arcing loops that is an excellent example of how a low-mass satellite accretion can produce a interweaved, rosette-like structure
