The Planck data strongly suggest that dust in the Milky Way galaxy might account for the entire signal interpreted as gravitational waves by researchers using BICEP2, the Antarctic telescope responsible for the initial discovery, which was announced in March.

The neutron stars» union also gave researchers the opportunity to gauge the universe's expansion rate, by measuring the distance of the collision using gravitational waves and comparing that to how much the wavelength of light from the galaxy was stretched by the expansion.

Astronomers have uncovered a supermassive black hole that has been propelled out of the center of a distant galaxy by what could be the awesome power of gravitational waves.

Comparing that galaxy's redshift with the distance of the merger as measured by the loudness of the gravitational waves could provide an independent estimate of the rate of cosmic expansion, possibly more accurate than current methods.

We can tell things like which galaxy the waves come from, if there are other stars nearby, and whether or not the gravitational waves are followed by visible radiation after a few hours or days.»

The most plausible explanation for this propulsive energy is that the monster object was given a kick by gravitational waves unleashed by the merger of two hefty black holes at the center of the host galaxy.

By 2018, they should be sensitive enough to detect gravitational waves originating from tens of thousands, if not hundreds of thousands, of galaxies, according to physicist and LIGO spokeswoman Gabriela Gonzalez.

Another experiment there, the South Pole Telescope, reported finding B - mode polarization last year, although the signal it saw was at a different angular scale across the sky and was clearly due to the known process of gravitational lensing (a warping of light caused by massive objects) of the CMB by large galaxies, rather than the primordial gravitational waves seen here.

In fact, the ring - like shape is the result of the gravitational disruption caused by a small intruder galaxy passing through a large one, compressing the interstellar gas and dust, and causing a wave of star formation wave to move out from the impact point like a ripple across the surface of a pond.

The origin of the spiral structure is thought to be in density waves which are triggered by gravitational disturbations, in particular during encounters with neighbor galaxies.

Besides confirming theories about the source of some short - duration gamma - ray bursts and the formation mechanism of many of the heavy elements including platinum, lead, gold, and rare earth elements, the gravitational waves enabled us to get a distance to the galaxy independent of the usual step - by - step procedure called the «distance scale ladder».

In an instant, the equivalent mass twice that of our sun was converted directly into gravitational waves — briefly producing more energy than all the energy that is radiated as light by all the galaxies in the universe at any moment, LIGO scientists say.

Gravitational waves may be produced in the heart of the galaxy, says a new study led by Ph.D..
