Galaxy growth in a massive halo in the first billion years of cosmic history
D. P. Marrone, J. S. Spilker, C. C. Hayward +34
According to the current understanding of cosmic structure formation, the precursors of the most massive structures in the Universe began to form shortly after the Big Bang, in reg…
H0LiCOW VIII. A weak lensing measurement of the external convergence in the field of the lensed quasar HE04351223
O. Tihhonova, F. Courbin, D. Harvey +10
We present a weak gravitational lensing measurement of the external convergence along the line of sight to the quadruply lensed quasar HE04351223. Using deep r-band images f…
DES meets Gaia: discovery of strongly lensed quasars from a multiplet search
A. Agnello, H. Lin, N. Kuropatkin +69
We report the discovery, spectroscopic confirmation and first lens models of the first two, strongly lensed quasars from a combined search in WISE and Gaia over the DES footprint.…
The Discovery of a Five-Image Lensed Quasar at z = 3.34 using PanSTARRS1 and Gaia
Fernanda Ostrovski, Cameron A. Lemon, Matthew W. Auger +8
We report the discovery, spectroscopic confirmation, and mass modelling of the gravitationally lensed quasar system PS J0630-1201. The lens was discovered by matching a photometric…
The Properties of Radio Galaxies and the Effect of Environment in Large Scale Structures at
Lu Shen, Neal A. Miller, Brian C. Lemaux +8
In this study we investigate 89 radio galaxies that are spectroscopically-confirmed to be members of five large scale structures in the redshift range of . Bas…
Flux-ratio anomalies from discs and other baryonic structures in the Illustris simulation
Jen-Wei Hsueh, Giulia Despali, Simona Vegetti +3
The flux ratios in the multiple images of gravitationally lensed quasars can provide evidence for dark matter substructure in the halo of the lensing galaxy if the flux ratios diff…
