Calculations modeling the effects of stellar evolution on elliptical galaxies (e.g., Bruzual and Kron 1980, Bruzual 1981) suggest that the shape of the spectral flux distribution should remain almost constant in the red and near-infrared out to at least z ~ 2. Thus, it should be possible ...

The meaning of REDSHIFT is a displacement of the spectrum of a celestial body toward longer wavelengths that is a consequence of the Doppler effect or the gravitational field of the source; also : a measurement of a celestial body's redshift equal to the

than any of the remotest galaxies previously observed. The extremely large redshifts of various quasars suggest that they are moving away from Earth at tremendous velocities (i.e., approximately 90 percent the speed of light) and therebyconstitutesome of the most distant objects in the universe...
What is the role of distant galaxies in galaxy formation models and the epoch of reionization? What are the conditions in typical star-forming galaxies at redshifts≳4? Why is galaxy evolution dependent on environment? The Spitzer Space Telescope has been a crucial tool for addressing these ...
