Sentences with phrase «central galaxy»

Unlike other central galaxies in clusters, this one is bursting with the birth of new stars.

Which is why astronomers were trying to understand how the massive central galaxy of the Phoenix cluster — a gigantic accumulation of about 1,000 galaxies 5.7 billion light - years away — was producing about 1,000 new stars every year.

A view of the four central galaxies at the heart of cluster Abell 3827, at a broader range of wavelengths, including Hubble Space Telescope imaging in the ultraviolet (shown as blue), and Atacama Large Millimetre Array imaging at very long (sub-mm) wavelengths (shown as red contour lines).

He emphasized: «The inevitable conclusion from this was that the majority of satellite galaxies stop forming stars relatively fast during the last 5 billion years as they fall to dense environments of clusters by way of the filaments, while this process is much slower for central galaxies.»

In the simulations, these dark matter thoroughfares connect major galactic hubs from all directions, so small galaxies should zip around the central galaxy at random.

The central galaxy in this cluster harbors a supermassive black hole that is in the process of devouring star - forming gas, which fuels a pair of powerful jets that erupt from the black hole in opposite directions into intergalactic space.

«We noticed that the dark matter seems to have become separated from [at least one of the central galaxy's] stars,» says Massey.

«Compared to the central galaxies, it is the smaller gravitational pull of the satellite galaxies produced by their smaller mass, that results in a more efficient loss of gas and hence, a slow - down in star formation activity with respect to the more massive central galaxies» said Chris Martin, a professor of astronomy at Caltech.

Manuel Meyer at Stockholm University led a study to search for these effects in the gamma rays from NGC 1275, the central galaxy of the Perseus galaxy cluster, located about 240 million light - years away.

The dust is located at the central galaxy and in smaller companion galaxies in its surroundings.

The water is located to the left and right of the central galaxy.

The first two disks zoom into the central galaxy cluster, the third disk (far right) demonstrates how an observation of the zoom area would look with an X-ray telescope («virtual telescope»).

Radio images had revealed a classic double - sided jet of energy streaming away from this central galaxy.

Focusing on the spectral features associated with the presence of iron in the central galaxy, the team determined that the majority of the emissions from highly ionized iron can be attributed to discrete sources.

The red clusters are believed to form as the galaxy forms, while the blue clusters are later brought in as smaller satellites are swallowed by the central galaxy.

Scientists say this star birth was triggered by a collision between a smaller galaxy and the giant, central galaxy.

A third study, also published in Physical Review Letters, looked for these tell - tale distortions in gamma - ray signals coming from the NGC 1275 — the central galaxy of the Perseus galaxy cluster.

But we saw these giant filaments of cold gas that extend 20,000 light years from the central black hole, beyond the central galaxy itself.
