cds-question@unistra.fractive-galactic-nucleih-i-line-emissionspectroscopyultraviolet-astronomyquasarsWe compile a catalog of reliable BLA (thermally broadened Ly{alpha} absorber) candidates along seven active galactic nucleus sight lines from a larger set of Ly{alpha} absorbers observed by the Space Telescope Imaging Spectrograph on the Hubble Space Telescope (HST). We compare our measurements based on independent reduction and analysis of the data to those published by other research groups. We examine the detailed structure of each absorber and determine a reliable line width and column density. Purported BLAs are grouped into probable (15), possible (48), and non-BLA (56) categories. Based on 164 measured curve of growth (COG) HI line measurements, we statistically correct the observed line widths via a Monte Carlo simulation. Finally, we present new, high signal-to-noise ratio observations of several of the BLA candidate lines from Early Release Observations made by the Cosmic Origins Spectrograph on HST.2010ApJ...710..613Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/710/613CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/182/378 : HI and OVI absorbers in nearby Universe (Wakker+, 2009)J/ApJ/701/1219 : Galaxy survey in 3 QSO fields (Chen+, 2009)J/ApJ/679/194 : Low-z intergalactic medium.
