• Techniques in high resolution observations from the ground and space, and imaging of the merging environments of radio galaxies at redshift 1 to 4 

  Steinbring, Eric (2018-08-03)

  High resolution imaging and spectroscopy are invaluable tools for extragalactic astronomy. Galaxies with redshifts of 1 or more subtend a very small angle on the sky—typically, only about an arcsecond. Unfortunately, this ...

• Proton cyclotron echo: a phenomenon of wave-wave and wave-particle interactions in topside sounding of the ionosphere 

  Chen, Guang-Ming (2018-07-09)

  Proton cyclotron echoes are phenomena related to the proton cyclotron frequency discovered On topside sounder swept-frequency ionograms from the Canadian satellite Alouette II in 1969. Subsequent studies were also limited ...
• A measurement of the partial width of the Z⁰ boson into b quarks and the forward-backward asymmetry in the reaction e⁺e⁻ -> Z⁰ -> bb, using inclusive electrons 

  Schenk, Paul Robert (2018-07-05)

  The process e+e- → Z0 → bb is studied using prompt electrons. The partial width of the Z0 boson into bb pairs is found to be 400 ± 35 ± 57 ± 3 MeV, and the forward-backward asymmetry in the reaction e+e- → Z0 → bb is found ...
• A cosmological field theory 

  Starkovich, Steven Paul (2018-07-04)

  Field theory is used to describe the material content of the universe throughout its entire history, and an oscillating cosmological model without a singularity is presented. In our theory, the “cosmological fluid” is ...
• Luminosity functions for old stellar systems 

  Bergbusch, Peter Anthony (2018-07-03)

  The potential for luminosity functions (LFs) of post-turnoff stars to constrain basic cluster parameters such as age, metallicity, and helium abundance is examined in this dissertation. A review of the published LFs for ...
• Analogue, numerical and field site studies of EM induction in the China-Korea-Japan region 

  Meng, Zhiwei (2018-06-27)

  Electromagnetic induction in the continental Bohai Bay coastal region of China and the island region of Japan is studied with the aid of laboratory analogue models. Detailed model measurements of the electric (Ex, Ey) ...
• A faint spectroscopic quasar survey 

  Schade, David Joseph (2018-06-22)

  A very faint spectroscopic quasar survey was undertaken in order to define the statistical behavior of the low luminosity portion of the quasar population at high redshift and to search for evidence of a decline in space ...
