Exciting news: Gravitational Waves detected!
We want to share our excitement about the first-ever direct detection of gravitational waves! The event happened right before the beginning of the first observing run of the advanced LIGO detectors, on 14 September 2015. The waves were generated as two black holes merged into a single black hole about 1.3 billion light years from Earth. In astronomy units this is 410 Mpc, approximately 10% of the way across the visible Universe!

Just as exciting: this is also the first-ever observation of binary black holes. In fact, since black holes are black, and emit no light or electromagnetic radiation, this is the only way we can see them.

Did Einstein@Home play any role in this? No, it didn’t. The signal in the instrument lasted only about 1/4 of a second. It’s not a continuous-wave signal like the type that Einstein@Home has been searching for. But since the observing run ended in mid January, we have been preparing the data to start a new low-frequency all-sky search for continuous gravitational waves. We are now starting to run this on Einstein@Home, so please sign up your computers and disable their sleep mode! In the next months we will extend the frequency range of the continuous waves all-sky searches, target interesting point sources and we are also gearing up to perform broader surveys for binary black hole mergers.

Public Update on first Advanced LIGO Observing Run
Dear Einstein@Home Volunteers,

Following the completion of the first Advanced LIGO Observing Run, the LIGO Laboratory and LIGO Scientific Collaboration will give a public update on the status and results on Thursday February 11th at 10:30 US Eastern Time.

Second Einstein@Home newsletter
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 runs”. The Einstein@Home team is truly excited and is looking forward to the most sensitive gravitational-wave data ever recorded.

In the first week of September more than 200 gravitational-wave scientists from the LIGO Virgo Scientific Collaboration gathered in Budapest for their fall meeting. Many Einstein@Home team members were present and reported on their ongoing gravitational-wave searches. During the meeting, the seventh issue of the LIGO Magazine was published, featuring a four page article on Einstein@Home. You can read it for free at [1].

Our second newsletter this year features news from the project administration and updates from our three searches for rapidly rotating neutron stars (through gravitational waves, radio waves, and gamma rays). We are very happy to report three new discoveries! One was made in data from NASA's Fermi Gamma-ray Space Telescope, and three were made in data from the Arecibo Radio Telescope. See below for more details on the discoveries.

Note that we are advertising a position for an Einstein@Home computational scientist at UWM in Milwaukee [2]. If you have the required skills and interest, please apply!

Einstein@Home in latest LIGO Magazine
The new LIGO magazine is out and it features an article about Einstein@Home. You read a pdf file of the article here. The article was written by M. Alessandra Papa, Benjamin Knispel, Holger Pletsch and Bernd Machenschalk from the Einstein@Home team, looking at the project's history, infrastructure, and different searches.

Do have a look at this and the earlier issues of the LIGO Magazine to learn more about the LIGO gravitational detectors.
