Searching for galaxy clusters in the Kilo-Degree Survey
M. Radovich, E. Puddu, F. Bellagamba +11
In this paper, we present the tools used to search for galaxy clusters in the Kilo Degree Survey (KiDS), and our first results. The cluster detection is based on an implementation…
The first and second data releases of the Kilo-Degree Survey
Jelte T. A. de Jong, Gijs A. Verdoes Kleijn, Danny R. Boxhoorn +46
The Kilo-Degree Survey (KiDS) is an optical wide-field imaging survey carried out with the VLT Survey Telescope and the OmegaCAM camera. KiDS will image 1500 square degrees in four…
The power spectrum of systematics in cosmic shear tomography and the bias on cosmological parameters
V. F. Cardone, M. Martinelli, E. Calabrese +5
Cosmic shear tomography has emerged as one of the most promising tools to both investigate the nature of dark energy and discriminate between General Relativity and modified gravit…
On the shear estimation bias induced by the spatial variation of colour across galaxy profiles
Elisabetta Semboloni, Henk Hoekstra, Zhuoyi Huang +13
The spatial variation of the colour of a galaxy may introduce a bias in the measurement of its shape if the PSF profile depends on wavelength. We study how this bias depends on the…
A weak lensing analysis of the Abell 383 cluster
Zhuoyi Huang, Mario Radovich, Aniello Grado +4
In this paper we use deep CFHT and SUBARU archival images of the Abell 383 cluster (z=0.187) to estimate its mass by weak lensing. To this end, we first use simulated imag…
