Sentences with phrase «as galaxy mergers»

This meant that objects that look similar to lenses, such as galaxy mergers, tidal tails and spiral arms, pairs of blue stars and so on, were specifically excluded from the training set, and therefore we expect some of those types of object to appear in the stage 1 candidate list.

Conroy suspects that violent conditions in the early universe — such as galaxy mergers — shocked and compressed gas and dust in particular areas, creating agglomerations of thousands of stars in particular areas.

Many other potential applications of this dataset are explored in the series of papers, and they include studying the role of faint galaxies during cosmic reionisation (starting just 380,000 years after the Big Bang), galaxy merger rates when the Universe was young, galactic winds, star formation as well as mapping the motions of stars in the early Universe.

A black hole merger in a massive galaxy like M87 would yield detectable gravitational waves for 4 million years, for instance, while a more modest galaxy such as the Sombrero Galaxy would offer a 160 - million - year window.

«Galaxies are shaped by collisions and mergers, as well as this sweeping of their gas from cosmic winds.

Each time a merger occurred, material from the new galaxy got incorporated into the accretion disk around the black hole, spinning in the same direction as the black hole and eventually contributing to its growth.

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.

Perhaps, after all, a relatively recent galactic merger is responsible for Andromeda's structure — and the structure of countless other galaxies — as well.

A new study has come to the startling conclusion that as many as half of all stars in the universe may be rogue, having been ejected from their birthplaces by galaxy collisions or mergers.

One scenario involves the gradual disturbance of a well - ordered disk of stars as a result of mergers with small satellite galaxies.

«Beads on a string» is a telltale sign of something known as a wet merger, which occurs when at least one galaxy in a collision between galaxies is gas rich, and this gas is converted quickly into new stars.

«We were looking for orbiting pairs of supermassive black holes, with one offset from the center of a galaxy, as telltale evidence of a previous galaxy merger.

Cosmological events such as mergers between galaxies can also boost the star - formation rate.

Black holes in the centers of galaxies could accelerate mergers between objects and produce more ripples in space - time, also known as gravitational waves, a new study suggests.

IRAS also discovered many previously unknown galaxies that emit most of their energy in the infrared portion of the electromagnetic spectrum (these are known as ultraluminous infrared galaxies), apparently owing to a massive burst of star formation during the merger of two galaxies.

Will Earth survive long enough to see this merger of galaxies, as depicted in the video above?
