Gravitational waves are minute distortions or ripples in spacetime caused by the acceleration of massive objects. They are produced by cataclysmic events such as the merger of binary black holes , the coalescence of binary neutron stars , supernova explosions and processes including those of the early universe shortly after the Big Bang .
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 adjectival forms of the names of astronomical bodies are not always easily predictable. Attested adjectival forms of the larger bodies are listed below, along with the two small Martian moons; in some cases they are accompanied by their demonymic equivalents, which denote hypothetical inhabitants of these bodies.
The Laser Interferometer Gravitational-Wave Observatory (LIGO) is a large-scale physics experiment and observatory designed to detect cosmic gravitational waves and to develop gravitational-wave observations as an astronomical tool. [1]
In June 2020, astronomers reported details of a compact binary merging, in the "mass gap" of cosmic collisions, of a first-ever 2.50–2.67 M ☉ "mystery object", either an extremely heavy neutron star (that was theorized not to exist) or a too-light black hole, with a 22.2–24.3 M ☉ black hole, that was detected as the gravitational wave GW190814.
A black hole is a region of spacetime wherein gravity is so strong that no matter or electromagnetic energy (e.g. light) can escape it. [2] Albert Einstein's theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.
The E-field of a surface plasmon polariton at a silver–air interface, at a frequency corresponding to a free-space wavelength of 10μm. At this frequency, the silver behaves approximately as a perfect electric conductor, and the SPP is called a Sommerfeld–Zenneck wave, with almost the same wavelength as the free-space wavelength.
