Seeing how galaxies form

Article Abstract:

Abundances of light elements and the isotropy of the cosmic microwave background radiation indicate the uniform distribution of gas in early Big Bang that formed into galaxies because of gravity. Galaxies in the early formation stage form stars rapidly and have areas of different concentration. These features characterize galaxies not reached to the steady state. The images obtained from the Hubble Space Telescope and Keck telescope are useful in studying the morphology of these galaxies.

Ripples of early starlight

Article Abstract:

Evidence for fluctuation in background infrared light from far-off cosmological sources larger than would be expected from unresolved galaxies in known populations suggest fluctuations in the light emitted by an early generation of oldest stars. The data from the research are not specific enough to predict the origin of the light but a high-redshift interpretation works if the emitting stars are hot, massive and bright.
