The FLAMINGO project: Baryonic impact on weak gravitational lensing convergence peak counts
Jeger C. Broxterman, Matthieu Schaller, Joop Schaye +12
Weak gravitational lensing convergence peaks, the local maxima in weak lensing convergence maps, have been shown to contain valuable cosmological information complementary to commo…
Dynamical masses of brightest cluster galaxies II: constraints on the stellar IMF
S. I. Loubser, H. Hoekstra, A. Babul +2
We use stellar and dynamical mass profiles, combined with a stellar population analysis, of 32 brightest cluster galaxies (BCGs) at redshifts of 0.05 0.30, to place c…
Constraining the masses of high-redshift clusters with weak lensing: Revised shape calibration testing for the impact of stronger shears and increased blending
B. Hernandez-Martin, T. Schrabback, H. Hoekstra +7
WL measurements have well-known shear estimation biases, which can be partially corrected for with the use of image simulations. We present an analysis of simulated images that mim…
Dynamical masses of brightest cluster galaxies I: stellar velocity anisotropy and mass-to-light ratios
S. I. Loubser, A. Babul, H. Hoekstra +3
We investigate the stellar and dynamical mass profiles in the centres of 25 brightest cluster galaxies (BCGs) at redshifts of 0.05 0.30. Our spectroscopy enables us t…
Euclid: The reduced shear approximation and magnification bias for Stage IV cosmic shear experiments
A. C. Deshpande, T. D. Kitching, V. F. Cardone +69
Stage IV weak lensing experiments will offer more than an order of magnitude leap in precision. We must therefore ensure that our analyses remain accurate in this new era. Accordin…
Cycling of the powerful AGN in MS 0735.6+7421 and the duty cycle of radio AGN in Clusters
A. N. Vantyghem, B. R. McNamara, H. R. Russell +5
We present an analysis of deep Chandra X-ray observations of the galaxy cluster MS 0735.6+7421, which hosts the most energetic radio AGN known. Our analysis has revealed two caviti…
