Sentences with phrase «at high redshift»

A merging pair of galaxies at high redshift appears to us as a pair of unresolved blobs that lie close to each other in the sky.
According to Jim Peebles of Princeton University, Lemaitre's framework for cosmology is still relevant today because it «consider [s] scenarios for the evolution of structure that start at high redshift with initial conditions that do not seem unduly conjured, evolve accordingto accepted laws of physics, and end up looking more or less like the universe we observe.»
The Baryon Oscillation Spectroscopic Survey (BOSS), the largest component of the third Sloan Digital Sky Survey (SDSS - III), pioneered the use of quasars to map density variations in intergalactic gas at high redshifts, tracing the structure of the young universe.
While the mass of tepid dust that we measure is insufficient by itself to account for the dust observed at high redshift, it does constitute an additional dust population to contribute to those previously reported.
His main current research interests are high energy astrophysics, especially gamma ray bursts, galactic nuclei, black hole formation and radiative processes (including gravitational waves) and cosmic structure formation, especially the early generation of stars and galaxies that formed at high redshifts at the end of the cosmic «dark age».
The workshop covers science topics that can be addressed using HI absorption (intervening and associated), including what we can learn about the feedback effects of AGNs on galaxy evolution, the properties of the ISM of galaxies at higher redshift, and the cosmic evolution of HI.
However, at high redshifts we require active, continuous accretion to infer the presence of the SMBHs, which often comes in the form of long - term accretion in active galactic nuclei.
Her research interests include structure, interactions, and star formation in galaxies in the local universe and at high redshift, and she observes in optical, near - infrared, and radio wavelengths.
«EGSY8p7 was found to be both luminous and at high redshift, and its colors measured by the Hubble and Spitzer Space Telescopes indicate it may be powered by a population of unusually hot stars.»
