Modeling Strong Lenses from Wide-Field Ground-Based Observations in KiDS and GAMA
Shawn Knabel, B. W. Holwerda, J. Nightingale +13
Despite the success of galaxy-scale strong gravitational lens studies with Hubble-quality imaging, the number of well-studied strong lenses remains small. As a result, robust compa…
Galaxy And Mass Assembly: Galaxy Morphology in the Green Valley, Prominent rings and looser Spiral Arms
Dominic Smith, Lutz Haberzettl, L. E. Porter +15
Galaxies broadly fall into two categories: star-forming (blue) galaxies and quiescent (red) galaxies. In between, one finds the less populated ``green valley". Some of these galaxi…
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…
Evidence of Increased UV FeII Emission in Quasars in Candidate Overdense Regions
Kathryn A. Harris, G. M. Williger, L. Haberzettl +6
We present evidence for a skewed distribution of UV FeII emission in quasars within candidate overdense regions spanning spatial scales of ~ 50 Mpc at 1.11 < z < 1.67, compared to…
GALEX selected Lyman Break Galaxies at z~2: Comparison with other Populations
L. Haberzettl, G. M. Williger, M. D. Lehnert +2
We present results of a search for bright Lyman break galaxies at 1.5<=z<=2.5 in the GOODS-S field using a NUV-dropout technique in combination with color-selection. We derived a s…
SOAR Imaging of sub-Damped Lyman-Alpha Systems at z<1
Joseph D. Meiring, James T. Lauroesch, Lutz Haberzettl +4
We present deep ground based imaging of the environments of five QSOs that contain sub-Damped Lyman-alpha systems at z<1 with the SOAR telescope and SOI camera. We detect a clear s…
