'Microlensing: Marching Toward a Complete Census of Cold Exoplanet Population'


Planetary microlensing search is on an accelerating pace. Over the
last five years, thanks to a strategic shift into focusing on
high-magnification events, a couple dozen new planets have been
discovered by a follow-up network of small and medium-size
telescopes. These findings offer us first glimpse at a largely uncharted
territory of exoplanet discovery space -- planets down to Earth mass
beyond the "snow line". I will review these discoveries and discuss
their implications. The field is quickly shifting to forming a global
network of wide-field 1-2m telescopes, expected to enhance the
discovery rate by orders of magnitude. The discovery potential of
microlensing will be fully unleashed by a space-based wide-field
IR telescope, such as WFIRST. I will talk about these future prospects at
the end.
