Intervening Mg II absorption systems from the SDSS DR12 quasar spectra
Srinivasan Raghunathan, Roger G. Clowes, Luis E. Campusano +3
We present the catalogue of the Mg II absorption systems detected at a high significance level using an automated search algorithm in the spectra of quasars from the twelfth data r…
Ultraviolet Fe II Emission in Fainter Quasars: Luminosity Dependences, and the Influence of Environments
Roger G. Clowes, Lutz Haberzettl, Srinivasan Raghunathan +5
We investigate the strength of ultraviolet Fe II emission in fainter quasars compared with brighter quasars for 1.0 <= z <= 1.8, using the SDSS (Sloan Digital Sky Survey) DR7QSO ca…
Systematic effects from an ambient-temperature, continuously-rotating half-wave plate
T. Essinger-Hileman, A. Kusaka, J. W. Appel +10
We present an evaluation of systematic effects associated with a continuously-rotating, ambient-temperature half-wave plate (HWP) based on two seasons of data from the Atacama B-Mo…
