Tracking Current Federal Legislation and Regulations: A Guide to Basic Sources

This report introduces selected basic sources that are useful in obtaining background information or specific facts on the status of federal legislative or regulatory initiatives. It includes telephone, online, and media sources are included, as well as pertinent directories, such as those of organizations that track areas of interest. Annotations describing each source's contents and organization are included so that researchers can select those that most closely fit their needs. Internet addresses usually provide information about the items, rather than access to them.

Massive Star Formation in a Gravitationally-Lensed H II Galaxy at z = 3.357 (open access)

Massive Star Formation in a Gravitationally-Lensed H II Galaxy at z = 3.357

The Lynx arc, with a redshift of 3.357, was discovered during spectroscopic follow-up of the z = 0.570 cluster RX J0848+4456 from the ROSAT Deep Cluster Survey. The arc is characterized by a very red R - K color and strong, narrow emission lines. Analysis of HST WFPC 2 imaging and Keck optical and infrared spectroscopy shows that the arc is an H II galaxy magnified by a factor of {approx} 10 by a complex cluster environment. The high intrinsic luminosity, the emission line spectrum, the absorption components seen in Ly{alpha} and C IV, and the restframe ultraviolet continuum are all consistent with a simple H II region model containing {approx} 10{sup 6} hot O stars. The best fit parameters for this model imply a very hot ionizing continuum (T{sub BB} {approx} 80, 000 K), high ionization parameter (log U {approx} -1), and low nebular metallicity (Z/Z{sub {circle_dot}} {approx} 0.05). The narrowness of the emission lines requires a low mass-to-light ratio for the ionizing stars, suggestive of an extremely low metallicity stellar cluster. The apparent overabundance of silicon in the nebula could indicate enrichment by past pair instability supernovae, requiring stars more massive than {approx}140M{sub {circle_dot}}.

Oral History Interview with Tom Ellison, March 2, 2004 transcript

Oral History Interview with Tom Ellison, March 2, 2004

The National Museum of the Pacific War presents an oral interview with Tom D. Ellison. Ellison was born 14 August 1925 in Sierra Blanca, Texas. He joined the Navy in September 1942. After 12 weeks of boot camp at the Farragut Naval Training Center, Idaho, he went for 21 weeks of aircraft maintenance training in Norman, Oklahoma, and 4 weeks of air gunnery training in Purcel, Oklahoma. This was followed by more maintenance and gunnery training at NAS Jacksonville. Next it was to NAS Oceana, Virginia working on and flying in PB4Y patrol planes. Ellison then sailed to England on the USS Matagorda (AVP-22). He spent from December 1943 to August 1945 at Dunkeswell Airfield in Devon. His squadron, VP-105, performed anti-submarine patrols in the English Channel and the North Sea. Following the German surrender, Ellison went to San Diego, Guam, Japan, and finally Shanghai, China to join a PBM Mariner squadron operating from a seaplane tender in the Whangpoo River. They provided passenger, mail, and air-sea rescue services in the area. Having advanced to AMM 1/C, Ellison was discharged from the Navy in San Diego.
