Physical Conditions In A Galactic Star Forming Region W22, Akshaya Rane
Physical Conditions In A Galactic Star Forming Region W22, Akshaya Rane
University of Kentucky Master's Theses
This document describes study of an active star forming region in our galaxy (the Milky Way) known as W22. Physical conditions in these regions can help us in understanding star formation processes in the universe and hence the structure and evolution of the universe. Zeeman effect measurements in 18 cm OH absorption line were carried out in order to estimate the line of sight magnetic field strength in the molecular cloud associated with this star forming region. Other physical parameters such as hydrogen column density, optical depth, critical magnetic field were also determined from these measurements. The region was mapped …
Magnetic Micro-Confinement Of Quantum Degenerate Gases, Ahmed M. Abdelrahman
Magnetic Micro-Confinement Of Quantum Degenerate Gases, Ahmed M. Abdelrahman
Theses: Doctorates and Masters
In this dissertation we explore the basic principles of the magnetic micro-confinement of the quantum degenerate gases where the approach of the so-called two-dimensional magnetic lattices has been theoretically and experimentally investigated. In this research a new generation of two-dimensional magnetic lattice has been proposed and considered as a developing phase for the previous approaches. Its advantage relies on introducing a simplified method to create single or multiple micro-traps of magnetic field local minima distributed, at a certain working distance, above the surface of a thin film of permanent magnetic material. The simplicity in creating the magnetic field local minima …
