Journal ArticleDOI

Observation of Gravitational Waves from a Binary Black Hole Merger

B. P. Abbott, +1011 more
TL;DR: This is the first direct detection of gravitational waves and the first observation of a binary black hole merger, and these observations demonstrate the existence of binary stellar-mass black hole systems.
Journal ArticleDOI

Tests of general relativity with GW150914

B. P. Abbott, +979 more
TL;DR: It is found that the final remnant's mass and spin, as determined from the low-frequency and high-frequency phases of the signal, are mutually consistent with the binary black-hole solution in general relativity.
Journal ArticleDOI

Astrophysical implications of the binary black hole merger gw150914

B. P. Abbott, +964 more
TL;DR: The discovery of the GW150914 with the Advanced LIGO detectors provides the first observational evidence for the existence of binary black-hole systems that inspiral and merge within the age of the Universe as mentioned in this paper.
Journal ArticleDOI

GW150914: The Advanced LIGO Detectors in the Era of First Discoveries

B. P. Abbott, +958 more
TL;DR: Following a major upgrade, the two advanced detectors of the Laser Interferometer Gravitational-wave Observatory (LIGO) held their first observation run between September 2015 and January 2016, and observed a transient gravitational-wave signal determined to be the coalescence of two black holes.
Journal ArticleDOI

Fugitive Methane Emissions from Indian Coal Mining and Handling Activities: Estimates, Mitigation and Opportunities for its Utilization to Generate Clean Energy☆

TL;DR: In this article, a time series data of coal production and associated fugitive methane emissions from coal mining and handling activities have been presented up to the year 2012, where it has been shown that utilization of VAM at Moonidih Mine of BCCL can lead to a net emission reduction of 0.62 million tonnes of CO 2 equivalent per year.
