Constraints on the inner density profile of dark-matter haloes from weak gravitational lensing
M. Viola, M. Maturi, M. Bartelmann
We construct two linear filtering techniques based on weak gravitational lensing to constrain the inner slope of the density profile of dark-matter halos. Both methods combine…
Tracing the evolution in the iron content of the ICM
I. Balestra, P. Tozzi, S. Ettori +5
We present a Chandra analysis of the X-ray spectra of 56 clusters of galaxies at z>0.3, which cover a temperature range 3<kT<15 keV. Our analysis is aimed at measuring the iron abu…
KiDS-i-800: Comparing weak gravitational lensing measurements in same-sky surveys
A. Amon, C. Heymans, D. Klaes +21
We present a weak gravitational lensing analysis of 815 square degree of -band imaging from the Kilo-Degree Survey (KiDS--800). In contrast to the deep -band observations,…
RCSLenS: Cosmic Distances from Weak Lensing
T. D. Kitching, M. Viola, H. Hildebrandt +7
In this paper we present results of applying the shear-ratio method to the RCSLenS data. The method takes the ratio of the mean of the weak lensing tangential shear signal about ga…
The galaxy environment in GAMA G3C groups using the Kilo Degree Survey Data Release 3
M. V. Costa-Duarte, M. Viola, A. Molino +13
We aim to investigate the galaxy environment in GAMA Galaxy Groups Catalogue (G3C) using a volume-limited galaxy sample from the Kilo Degree Survey Data Release 3. The k-Nearest Ne…
RCSLenS: A new estimator for large-scale galaxy-matter correlations
A. Buddendiek, P. Schneider, H. Hildebrandt +9
We present measurements of the galaxy bias and the galaxy-matter cross-correlation coefficient for the BOSS LOWZ luminous red galaxy sample. Using a new statistical weak le…
