Query: Reproducing GW150914: the first observation of gravitational waves from
  a binary black hole merger   In 2016, LIGO and Virgo announced the first observation of gravitational
waves from a binary black hole merger, known as GW150914. To establish the
confidence of this detection, large-scale scientific workflows were used to
measure the event's statistical significance. They used code written by the
LIGO/Virgo and were executed on the LIGO Data Grid. The codes are publicly
available, but there has not yet been an attempt to directly reproduce the
results, although several analyses have replicated the analysis, confirming the
detection. We attempt to reproduce the result presented in the GW150914
discovery paper using publicly available code on the Open Science Grid. We show
that we can reproduce the main result but we cannot exactly reproduce the LIGO
analysis as the original data set used is not public. We discuss the challenges
we encountered and make recommendations for scientists who wish to make their
work reproducible.
