Ongoing magnetic monopole searches with IceCube
  The IceCube collaboration has instrumented a cubic kilometer of ice with
$5160$ photo-multipliers. While mainly developed to detect Cherenkov light, any
visible light can be used to detect particles within the ice. Magnetic
monopoles are hypothetical particles predicted by many theories that extend the
Standard model of Particle Physics. They are carriers of a single elementary
magnetic charge. For this particle, different light production mechanisms
dominate from direct Cherenkov light at highly relativistic velocities
$\left(>0.76\,c\right)$, indirect Cherenkov light at mildly relativistic
velocities $\left(\approx 0.5\,c \textrm{ to } 0.76\,c\right)$, luminescence
light at low relativistic velocities $\left( \gtrsim 0.1\,c \textrm{ to }
0.5\,c\right)$, as well as catalysis of proton decay at non relativistic
velocities $\left(\lesssim 0.1\,c\right)$. For each of this speed ranges,
searches for magnetic monopoles at the IceCube experiment are either in
progress or they have already set the world's best limits on the flux of
magnetic monopoles. A summary of these searches will be presented, outlining
already existing results as well as methods used by the currently conducted
searches.
