    Abstract: The conventional view is that the cosmic spectral-redshift, an effect observed in all directions of the heavens, is primarily a measure of space-medium expansion. Significantly, the more distant the galaxy the greater is the redshift — and the greater is the intervening space expansion. The redshift evidence is unequivocal; its implication, its int...

  • Optical Luminosity Function of Quasi Stellar Objects

    Abstract: We study the shape of the optical luminosity function of Quasi Stellar Objects (QSOs) from the Sloan Digital Sky Survey Data Release Seven (SDSS DR7) over the redshift range 0.3 ≤ Z ≤ 2.4. By using the Levenberg-Marquardt method of nonlinear least square fit, the observed QSO luminosity function is fitted by a double power-law model with luminosity... Show More
  • A GAIA Revised Oort Cloud Encounter with Gliese 710

    Martin Beech, Lowell Peltier

    Published: 12 December 2016
    Abstract: The encounter between Gliese 710 and the solar system is re-examined in light of the newly published parallax and proper motion measurements within the GAIA data 1 release. The up-dated astrometric parameters are found to be significantly different from those implicated by the earlier Hipparcos Catalog and the revised encounter will see GL 710 pass... Show More
  • Application of Atomic and Molecular Physics in the Atmosphere

    Mohamed Habib Ahmed Elkanzi, Abdelnabi Ali Elamin

    Abstract: The most important of a long term changes in structure of the atmosphere due to the concentration of various species in the upper atmosphere. The gaseous or vaporous shell that surrounds the earth. When early man first sought to understand his physics environment, his greatest awe surely concerned the sun, moon, planets, and stars (which became the... Show More
