Cross-correlating Planck tSZ with RCSLenS weak lensing: Implications for cosmology and AGN feedback
Alireza Hojjati, Tilman Tröster, Joachim Harnois-Déraps +11
We present measurements of the spatial mapping between (hot) baryons and the total matter in the Universe, via the cross-correlation between the thermal Sunyaev-Zeldovich (tSZ) map…
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…
Multi-wavelength scaling relations in galaxy groups: a detailed comparison of GAMA and KiDS observations to BAHAMAS simulations
Arthur Jakobs, Massimo Viola, Ian McCarthy +18
We study the scaling relations between the baryonic content and total mass of groups of galaxies, as these systems provide a unique way to examine the role of non-gravitational pro…
KiDS-450: Tomographic Cross-Correlation of Galaxy Shear with {\it Planck} Lensing
Joachim Harnois-Déraps, Tilman Tröster, Nora Elisa Chisari +14
We present the tomographic cross-correlation between galaxy lensing measured in the Kilo Degree Survey (KiDS-450) with overlapping lensing measurements of the cosmic microwave back…
CFHTLenS revisited: assessing concordance with Planck including astrophysical systematics
Shahab Joudaki, Chris Blake, Catherine Heymans +9
We investigate the impact of astrophysical systematics on cosmic shear cosmological parameter constraints from the Canada-France-Hawaii Telescope Lensing Survey (CFHTLenS), and the…
KiDS-450 + 2dFLenS: Cosmological parameter constraints from weak gravitational lensing tomography and overlapping redshift-space galaxy clustering
Shahab Joudaki, Chris Blake, Andrew Johnson +19
We perform a combined analysis of cosmic shear tomography, galaxy-galaxy lensing tomography, and redshift-space multipole power spectra (monopole and quadrupole) using 450 deg…
