The signal, GW151226, was observed by the twin detectors of the Laser Interferometer Gravitational-Wave Observatory (LIGO) on December 26, 2015 at 03:38:53 UTC. The signal was initially identified within 70 s by an online matched-filter search targeting binary coalescences. Subsequent off-line analyses recovered GW151226 with a network signal-to-noise ratio of 13 and a significance greater than 5σ. The signal persisted in the LIGO frequency band for approximately 1 s, increasing in frequency and amplitude over about 55 cycles from 35 to 450 Hz, and reached a peak gravitational strain of 3.4_{-0.9}^{+0.7}×10^{-22}. The inferred source-frame initial black hole masses are 14.2_{-3.7}^{+8.3}M_{⊙} and 7.5_{-2.3}^{+2.3}M_{⊙}, and the final black hole mass is 20.8_{-1.7}^{+6.1}M_{⊙}. We find that at least one of the component black holes has spin greater than 0.2. This source is located at a luminosity distance of 440_{-190}^{+180}  Mpc corresponding to a redshift of 0.09_{-0.04}^{+0.03}. All uncertainties define a 90% credible interval. This second gravitational-wave observation provides improved constraints on stellar populations and on deviations from general relativity.","context":{"all":{"count":5406922,"mean":6.3053697795836,"rank":4816,"pct":99,"higher_than":5402108},"journal":{"count":13927,"mean":9.7047847192302,"rank":11,"pct":99,"higher_than":13916},"similar_age_3m":{"count":195243,"mean":10.964772344065,"rank":697,"pct":99,"higher_than":194546},"similar_age_journal_3m":{"count":289,"mean":21.167395833333,"rank":2,"pct":99,"higher_than":287}},"type":"article","altmetric_id":8767198,"schema":"1.5.4","is_oa":false,"publisher_subjects":[{"name":"Physical Sciences","scheme":"era"}],"cited_by_posts_count":306,"cited_by_msm_count":24,"cited_by_feeds_count":13,"cited_by_tweeters_count":193,"cited_by_fbwalls_count":21,"cited_by_wikipedia_count":10,"cited_by_gplus_count":23,"cited_by_qna_count":1,"cited_by_accounts_count":285,"last_updated":1469568032,"score":445.936,"history":{"1y":431.808,"6m":431.808,"3m":431.808,"1m":24.15,"1w":3.35,"6d":3.35,"5d":2.35,"4d":2.35,"3d":2.35,"2d":1.35,"1d":1.35,"at":445.936},"url":"http://dx.doi.org/10.1103/physrevlett.116.241103","added_on":1466011190,"published_on":1465948800,"subjects":["medicine"],"scopus_subjects":["Physics and Astronomy","Physical Sciences"],"readers":{"citeulike":"0","mendeley":"24","connotea":"0"},"readers_count":24,"images":{"small":"https://altmetric-badges.a.ssl.fastly.net/?size=64&score=446&types=qmbttwfg","medium":"https://altmetric-badges.a.ssl.fastly.net/?size=100&score=446&types=qmbttwfg","large":"https://altmetric-badges.a.ssl.fastly.net/?size=180&score=446&types=qmbttwfg"},"details_url":"http://www.altmetric.com/details.php?citation_id=8767198"})
