Sentences with phrase «galaxies were closer to each other»

Not exact matches

Using simulations to measure how radiation from one galaxy influenced black hole formation in the other, the researchers found that the neighboring galaxy could be smaller and closer than previously estimated.

«Many of the stars in the bridge appear to have been removed from the SMC in the most recent interaction, some 200 million years ago, when the dwarf galaxies passed relatively close by each other.

Other so - called hypervelocity stars are thought to have been boosted to their high speeds by close encounters with our galaxy's supermassive black hole (see Hypervelocity stars: Catch them while you can), but this star is too young to have travelled all the way from the centre of the Milky Way.

The theoretical engine of this growth turns out to be complex: New galaxies get pulled in and stretched around the halo like strings of spaghetti, maintaining the signature of their independent origin; galaxies closer to the central bulge get mixed up with other old structures, losing the hallmarks of their original form.

Ghost - like particles that were first created in the instant following the Big Bang, antineutrinos and their partner neutrinos travel at close to the speed of light and are notoriously difficult to observe as they move through space, passing through planets, star systems, and galaxies with scant interactions with other forms of matter.

Since the 1960s Margaret and a few others have been collecting examples of galaxies and quasars in seemingly close proximity to one another.

These two galaxies are close companions and it is likely that a recent close encounter has left both galaxies looking very similar to each other.

The reasonable assumption is that we do not live at a special time, so the galaxies in the cluster must have always been close to each other.

«This contrasts with the recent X-ray determinations of (close to) maximal black hole spin in other [similar galaxies] based on relativistic smearing of the iron profile,» the researchers wrote in the study, which was published online today (July 29) in the journal Monthly Notices of the Royal Astronomical Society.

However, other measurements taken by a team of researchers from the University of Strasbourg in France appear to show that stars just outside of Triangulum II are moving faster than the ones close to the galactic center — which were used by Kirby to determine the galaxy's mass.

Another result from the study is that the jet structure in NGC 1275 significantly differs from the jet in the very nearby galaxy Messier 87, which is the only other jet whose structure has been imaged equally close to the black hole.

The galaxies in the two groups are physically close to each other and the groups seem to not be moving relative to each other, so they are often identified as a single galaxy group.
