In gravitational-wave astronomy, observations of gravitational waves are used to infer data about the sources of gravitational waves. Sources that can be studied this way include binary star systems composed of white dwarfs , neutron stars , [ 8 ] [ 9 ] and black holes ; events such as supernovae ; and the formation of the early universe ...
The blue lines are gravitational waves, ripples in time and space, which is how astronomers detected the merger, and orange and red areas indicate parts of the neutron star being stripped away.
The first direct observation of gravitational waves was made on 14 September 2015 and was announced by the LIGO and Virgo collaborations on 11 February 2016. [3] [4] [5] Previously, gravitational waves had been inferred only indirectly, via their effect on the timing of pulsars in binary star systems.
In gravitational-wave astronomy, observations of gravitational waves are used to infer data about the sources of gravitational waves. Sources that can be studied this way include binary star systems composed of white dwarfs , neutron stars , and black holes ; events such as supernovae ; and the formation of the early universe shortly after the ...
Scientists on Wednesday unveiled evidence that gravitational waves, the ripples in the fabric of space-time predicted by Albert Einstein more than a century ago, are permeating the universe at low ...
First discovered in 2015 by the Laser Interferometer Gravitational-Wave Observatory, or LIGO, gravitational waves are physical ripples in spacetime caused by objects with mass moving through space ...
Not long after the first suggestions of pulsars being used for gravitational wave detection in the late 1970’s, [11] [12] Donald Backer discovered the first millisecond pulsar in 1982. [13] The following year Ron Hellings and George Downs published the foundations of the Hellings-Downs curve in their 1983 paper "Upper Limits on the Isotropic ...
Moreover, gravitational waves from such a supernova will bring volumes of information about the dynamics of the central engine powering these explosions, something the ORNL-UT supernova group has ...
