Dynamical cluster masses from photometric surveys
Omar Contigiani, Henk Hoekstra, Margot M. Brouwer +5
The masses of galaxy clusters can be measured using data obtained exclusively from wide photometric surveys in one of two ways: directly from the amplitude of the weak lensing sign…
The Weak Lensing Radial Acceleration Relation: Constraining Modified Gravity and Cold Dark Matter theories with KiDS-1000
Margot M. Brouwer, Kyle A. Oman, Edwin A. Valentijn +22
We present measurements of the radial gravitational acceleration around isolated galaxies, comparing the expected gravitational acceleration given the baryonic matter with the obse…
GAMA+KiDS: Empirical correlations between halo mass and other galaxy properties near the knee of the stellar-to-halo mass relation
Edward N. Taylor, Michelle E. Cluver, Alan Duffy +16
We use KiDS weak lensing data to measure variations in mean halo mass as a function of several key galaxy properties (namely: stellar colour, specific star formation rate, Sersic i…
Observational constraints on the slope of the radial acceleration relation at low accelerations
Kyle A. Oman, Margot M. Brouwer, Aaron D. Ludlow +1
The radial acceleration relation (RAR) locally relates the `observed' acceleration inferred from the dynamics of a system to the acceleration implied by its baryonic matter distrib…
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…
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…
A KiDS weak lensing analysis of assembly bias in GAMA galaxy groups
Andrej Dvornik, Marcello Cacciato, Konrad Kuijken +19
We investigate possible signatures of halo assembly bias for spectroscopically selected galaxy groups from the GAMA survey using weak lensing measurements from the spatially overla…
First test of Verlinde's theory of Emergent Gravity using Weak Gravitational Lensing measurements
Margot M. Brouwer, Manus R. Visser, Andrej Dvornik +19
Verlinde (2016) proposed that the observed excess gravity in galaxies and clusters is the consequence of Emergent Gravity (EG). In this theory the standard gravitational laws are m…
Dependence of GAMA galaxy halo masses on the cosmic web environment from 100 square degrees of KiDS weak lensing data
Margot M. Brouwer, Marcello Cacciato, Andrej Dvornik +31
Galaxies and their dark matter haloes are part of a complex network of mass structures, collectively called the cosmic web. Using the tidal tensor prescription these structures can…
The stellar-to-halo mass relation of GAMA galaxies from 100 square degrees of KiDS weak lensing data
Edo van Uitert, Marcello Cacciato, Henk Hoekstra +26
We study the stellar-to-halo mass relation of central galaxies in the range 9.7<log_10(M_*/h^-2 M_sun)<11.7 and z<0.4, obtained from a combined analysis of the Kilo Degree Survey (…
Dark matter halo properties of GAMA galaxy groups from 100 square degrees of KiDS weak lensing data
M. Viola, M. Cacciato, M. Brouwer +24
The Kilo-Degree Survey (KiDS) is an optical wide-field survey designed to map the matter distribution in the Universe using weak gravitational lensing. In this paper, we use these…
Gravitational Lensing Analysis of the Kilo Degree Survey
Konrad Kuijken, Catherine Heymans, Hendrik Hildebrandt +32
The Kilo-Degree Survey (KiDS) is a multi-band imaging survey designed for cosmological studies from weak lensing and photometric redshifts. It uses the ESO VLT Survey Telescope wit…
The masses of satellites in GAMA galaxy groups from 100 square degrees of KiDS weak lensing data
Cristóbal Sifón, Marcello Cacciato, Henk Hoekstra +23
We use the first 100 sq. deg. of overlap between the Kilo-Degree Survey (KiDS) and the Galaxy And Mass Assembly (GAMA) survey to determine the galaxy halo mass of ~10,000 spectrosc…
