Schmidt discovered that these were in fact hydrogen lines that have been redshifted by an amount . = Δλ/λ. = 0.158. Hence it was realized that if 3C 273 obeys the Hubble law, it is at an extremely large distance and has an enormous intrinsic l

Advances in Nutritional Researchnsion (.. ∝ ..), which tends to dilute all local overdensities. The result is that the growth of fluctuations in an expanding universe is slow. For baryons this increase only begins at recombination (.. ≈ 1000) and in the linear phase the density contrast only grows by a factor (1 + ..) ≈ 10.. Now t

The Classification and Morphology of Galaxies,ects in total). The apparent magnitude is equal to ?2.5 log (luminosity). The eye can only perceive stars up to a magnitude . = 6. Up to an apparent magnitude . = 17.5 there are 500 000 galaxies, and up to . = 23, 10.. The first step in getting to know the galaxies better is to describe the various

The Classification and Morphology of Galaxies,ated definitively that certain nebulae do not form part of our Galaxy but are ‘island universes’, independent conglomerations of stars, gas, and dust. The historical confusion between the nebulae of ionized gas in the Milky Way and the external galaxies derives from the use of general catalogues, su
