Globular clusters in NGC 5907's stellar stream

We study the globular clusters (GCs) in the spiral galaxy NGC 5907 well-known for its spectacular stellar stream - to better understand its origin. Using wide-field Subaru/Suprime-Cam gri images and deep Keck/DEIMOS multi-object spectroscopy, we identify and obtain the kinematics of several GCs superimposed on the stellar stream and the galaxy disc. We estimate the total number of GCs in NGC 5907 to be 154+/-44, with a specific frequency of 0.73+/-0.21. Our analysis also reveals a significant, new population of young star cluster candidates found mostly along the outskirts of the stellar disc. Using the properties of the stream GCs, we estimate that the disrupted galaxy has a stellar mass similar to the Sagittarius dwarf galaxy accreted by the Milky Way, i.e. ~10^8^M_{sun}_.
