| 요약 | Current Lambda Cold-Dark-Matter cosmology predicts the growth of large scale structure from small, initial perturbations in the dark matter potential distribution. Gas in the Universe follows this dark matter potential, collapsing along a series |
| 요약 | This study is made possible by correlating the positions of archival Cosmic Origins Spectrograph (COS |
| 요약 | I introduce a novel likelihood method to automate the process of matching galaxies from this catalog with nearby absorption and also to quantify the relative isolation of these absorbers versus their proximity to galaxies. To test this method, I |
| 요약 | To test for a rotational Lyalpha component, I obtain long-slit rotation curve observations for 12 galaxies with the Southern African Large Telescope. I combine this sample with an additional 17 galaxies from the literature, and develop a halo ro |
| 요약 | Finally, I produce a sample of 1135 Lyalpha absorbers from 264 individual QSO spectra taken by COS and employ our likelihood method to sort them by galaxy proximity. I find that Lyalpha equivalent width depends strongly on galaxy proximity, with |
