The hidden past of M92: Detection and characterization of a newly formed
  17{\deg} long stellar stream using the Canada-France Imaging Survey
  We present an analysis of the structure, kinematics and orbit of a newly
found stellar stream emanating from the globular cluster M92 (NGC 6341). This
stream was discovered in an improved matched-filter map of the outer Galaxy,
based on a "color-color-magnitude" diagram, created using photometry from the
Canada-France Imaging Survey (CFIS) and the Pan-STARRS 1 3$\pi$ survey (PS1).
We find the stream to have a length of 17{\deg} (2.5 kpc at the distance of
M92), a width dispersion of $0.29${\deg}(42 pc) and a stellar mass of $[3.17
\pm{0.89}] \times 10^{4} $ M$_\odot$ ($10 \%$ of the stellar mass of the
current main body of M92). We examine the kinematics of main sequence, red
giant and blue horizontal branch stars belonging to the stream and that have
proper motion measurements from the second data release of Gaia. N-body
simulations suggest that the stream was likely formed very recently (during the
last $\sim 500$ Myr) forcing us to question the orbital origin of this ancient,
metal-poor globular cluster.
