Mapping tidal streams in the Galactic halo with Pan-STARRS The Pan-STARRS1 3Pi Survey has observed the whole sky north of Dec=-30 degrees, including the dense inner regions of our Galaxy. With a sky coverage spanning twice that of the SDSS footprint and deeper photometry, it offers the possibility to survey the Milky Way halo for stellar streams over a larger volume. I will give an overview of our ongoing work mapping both known and new streams as seen by Pan-STARRS1.
