KiDS+VIKING-450: A new combined optical & near-IR dataset for cosmology and astrophysics
Angus H. Wright, Hendrik Hildebrandt, Konrad Kuijken +22
We present the curation and verification of a new combined optical and near infrared dataset for cosmology and astrophysics, derived from the combination of -band imaging fro…
KiDS+VIKING-450: Cosmic shear tomography with optical+infrared data
H. Hildebrandt, F. Köhlinger, J. L. van den Busch +25
We present a tomographic cosmic shear analysis of the Kilo-Degree Survey (KiDS) combined with the VISTA Kilo-Degree Infrared Galaxy Survey (VIKING). This is the first time that a f…
Weak Lensing Reveals a Tight Connection Between Dark Matter Halo Mass and the Distribution of Stellar Mass in Massive Galaxies
Song Huang, Alexie Leauthaud, Andrew Hearin +9
Using deep images from the Hyper Suprime-Cam (HSC) survey and taking advantage of its unprecedented weak lensing capabilities, we reveal a remarkably tight connection between the s…
GMRT 610 MHz observations of galaxy clusters in the ACT equatorial sample
Kenda Knowles, Andrew J. Baker, J. Richard Bond +11
We present Giant Metrewave Radio Telescope 610 MHz observations of 14 Atacama Cosmology Telescope (ACT) clusters, including new data for nine. The sample includes 73\% of ACT equat…
Galaxy Cluster Mass Reconstruction Project - IV. Understanding the effects of imperfect membership on cluster mass estimation
R. Wojtak, L. Old, G. A. Mamon +17
The primary difficulty in measuring dynamical masses of galaxy clusters from galaxy data lies in the separation between true cluster members from interloping galaxies along the lin…
Studying galaxy troughs and ridges using Weak Gravitational Lensing with the Kilo-Degree Survey
Margot M. Brouwer, Vasiliy Demchenko, Joachim Harnois-Déraps +15
We study projected underdensities in the cosmic galaxy density field known as 'troughs', and their overdense counterparts, which we call 'ridges'. We identify these regions using a…
