Dear Einstein@Home volunteers,
the five-year upgrade of the LIGO detectors has been completed and we are a large step closer to the first direct detection of gravitational waves, which will mark the beginning of a new era of astronomy. As we are writing this newsletter, Advanced LIGO is beginning its first observation run “O1†after an extensive comissioning phase and a series of “engineering runsâ€. The Einstein@Home team is truly excited and is looking forward to the most sensitive gravitational-wave data ever recorded.
