usd to narrow down the location of the fast radio burst FRB 150418.
The large 8.2m Subaru telescope was used to image the host galaxy of
the fast radio burst. Deep spectroscopy from Keck and Subaru was
used to identify the galaxy distance and propoerties. This is the
first time a host galaxy to a fast radio burst was discovered and
the first confirmation that fast radio bursts originate from great
distances across the Universe.

Artist's impression of our technique used to
detect and measure galaxy-sized gas clouds (called DLAs) in the
early Universe. Light from extended background galaxies is used
to illuminate the foreground gas clouds as the light journeys to
Earth. The technique provides a 100 million-fold increase in the
measurement of DLA sizes as opposed to the typical method using quasars.
