Sentences with phrase «galactic mergers»

"Galactic mergers" refers to the coming together of two or more galaxies in space. It happens when galaxies get close enough to each other and their gravitational pull causes them to merge into a single larger galaxy. Full definition
The multiple rounds of galactic mergers that have since taken place have given us hefty galaxies like our Milky Way and nearby Andromeda.
«Best evidence yet for galactic merger in distant protocluster.»
Perhaps, after all, a relatively recent galactic merger is responsible for Andromeda's structure — and the structure of countless other galaxies — as well.
«Some supermassive black holes spin at more than 90 % of the speed of light, which suggests that they gained their mass through major galactic mergers
The Hubble Space Telescope has done it again, capturing an incredibly detailed, macabre view of a dramatic galactic merger.
Detection of the spiral's dust in a bi-symmetric structure provides strong evidence of its position deep inside the giant elliptical host while the vast amounts of radio, visual, and x-ray emissions are a result of the energy released by this continuing galactic merger (or «consumption» of a satellite galaxy).
It may also not be very advisable to be in regions of space close to supermassive black holes that combine during the process of galactic mergers (not that it ever is).
The team determined that galactic winds alone could not replenish the newly revealed gaseous reservoirs and suggests that the mass is provided by galactic mergers or accretion from hidden streams of gas, as predicted by current theory.
Stars forming like a string of blue pearls along two elliptical galaxies could be the result of a galactic merger, according to an international team of astronomers.
These results suggest that quasars are not a good proxy for protoclusters and more importantly, mechanisms other than galactic mergers may be needed to explain quasar activity.
These close encounters and galactic mergers are surprisingly commonplace, and could even be an important factor in the evolution of some spiral galaxies.
Here, they'd look to galactic mergers.
Since most galaxies in the universe are believed to harbor one supermassive black hole at their center, the presence of a binary system is conclusive evidence of a galactic merger.
Observations made using NASA's NuSTAR telescope have revealed that supermassive black holes in merging galaxies do most of their feeding during the later stages of galactic mergers, when they're heavily obscured.
