Sentences with phrase «galaxy groups identified»

Hubble photometry of one of the three galaxy groups identified at z ~ 8, with the galaxies in the image labeled with their corresponding approximate photometric redshifts.

Not exact matches

But within hours, five groups had identified a new source of light in the periphery of galaxy NGC 4993, which they watched fade from bright blue to dim red in a matter of days.

To identify the final shapes of galaxies after mergers observationally, the group studied the distribution of gas in 37 galaxies that are in their final stages of merging.

According to Loeb, the black hole that Condon's group think they have identified probably had its galaxy shredded, because it held on to a few stars — if it had been in a black hole merger or a three - body scuffle, it would have lost everything.

The group identified strong signals of CH + in five out of the six galaxies studied, including the Cosmic Eyelash [2] ALMA was used to obtain spectra of each galaxy.

Examples of science projects enabled by the data in the High - Latitude Survey include: mapping the formation of cosmic structure in the first billion years after the Big Bang via the detection and characterization of over 10,000 galaxies at z > 8; finding over 2,000 QSOs at z > 7; quantifying the distribution of dark matter on intermediate and large scales through lensing in clusters and in the field; identifying the most extreme star - forming galaxies and shock - dominated systems at 1 < z < 2; carrying out a complete census of star - forming galaxies and the faint end of the QSO luminosity function at z ~ 2, including their contribution to the ionizing radiation; and determining the kinematics of stellar streams in the Local Group through proper motions.

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.
