Low-Frequency Carbon Recombination Lines in the Orion Molecular Cloud Complex
Embargo Lift Date
MetadataShow full item record
We detail tentative detections of low-frequency carbon radio recombination lines from within the Orion molecular cloud complex observed at 99–129 MHz. These tentative detections include one alpha transition and one beta transition over three locations and are located within the diffuse regions of dust observed in the infrared at 100 µm, the Ha emission detected in the optical, and the synchrotron radiation observed in the radio. With these observations, we are able to study the radiation mechanism transition from collisionally pumped to radiatively pumped within the H ii regions within the Orion molecular cloud complex.

Analysis of candidate genes within the 3p14-p22 region of the human genome for association with bone mineral density phenotypesMullin, Benjamin H (2011)Previous studies have identified the 3p14-p22 chromosomal region as a quantitative trait locus for bone mineral density (BMD). The overall aim of this thesis is to identify the gene or genes from this region that are ...
