ATCA observations of the MACS-Planck Radio Halo Cluster Project II. Radio observations of an intermediate redshift cluster sample
G. Martinez Aviles, M. Johnston-Hollitt, C. Ferrari +16
A fraction of galaxy clusters host diffuse radio sources whose origins are investigated through multi-wavelength studies of cluster samples. We investigate the presence of diffuse…
Constraining self-interacting dark matter with scaling laws of observed halo surface densities
Kyrylo Bondarenko, Alexey Boyarsky, Torsten Bringmann +1
The observed surface densities of dark matter halos are known to follow a simple scaling law, ranging from dwarf galaxies to galaxy clusters, with a weak dependence on their virial…
Dark Energy Survey Year 1 Results: galaxy mock catalogues for BAO

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…
The BAHAMAS project: the CMB--large-scale structure tension and the roles of massive neutrinos and galaxy formation
Ian G. McCarthy, Simeon Bird, Joop Schaye +3
Recent studies have presented evidence for tension between the constraints on Omega_m and sigma_8 from the cosmic microwave background (CMB) and measurements of large-scale structu…
Chasing the peak: optimal statistics for weak shear analyses
Merijn Smit, Konrad Kuijken
Weak gravitational lensing analyses are fundamentally limited by the intrinsic, non-Gaussian distribution of galaxy shapes. We explore alternative statistics for samples of ellipti…
The MUSE Hubble Ultra Deep Field Survey VI: The Faint-End of the Lya Luminosity Function at 2.91 < z < 6.64 and Implications for Reionisation
A. B. Drake, T. Garel, L. Wisotzki +19
We present the deepest study to date of the Lya luminosity function (LF) in a blank field using blind integral field spectroscopy from MUSE. We constructed a sample of 604 Lya emit…
KiDS+2dFLenS+GAMA: Testing the cosmological model with the statistic
A. Amon, C. Blake, C. Heymans +17
We present a new measurement of , which combines measurements of weak gravitational lensing, real-space galaxy clustering and redshift space distortions. This statistic…
The diverse density profiles of galaxy clusters with self-interacting dark matter plus baryons
Andrew Robertson, Richard Massey, Vincent Eke +10
We present the first simulated galaxy clusters (M_200 > 10^14 Msun) with both self-interacting dark matter (SIDM) and baryonic physics. They exhibit a greater diversity in both dar…
Neutrino Mass Priors for Cosmology from Random Matrices
Andrew J. Long, Marco Raveri, Wayne Hu +1
Cosmological measurements of structure are placing increasingly strong constraints on the sum of the neutrino masses, , through Bayesian inference. Because these constraints…
Sunyaev-Zel'dovich Effect and X-ray Scaling Relations from Weak-Lensing Mass Calibration of 32 SPT Selected Galaxy Clusters
J. P. Dietrich, S. Bocquet, T. Schrabback +27
Uncertainty in the mass-observable scaling relations is currently the limiting factor for galaxy cluster based cosmology. Weak gravitational lensing can provide a direct mass calib…
Do current cosmological observations rule out all Covariant Galileons?
Simone Peirone, Noemi Frusciante, Bin Hu +2
We revisit the cosmology of Covariant Galileon gravity in view of the most recent cosmological data sets, including weak lensing. As a higher derivative theory, Covariant Galileon…
Extracting cosmological information from the angular power spectrum of the 2MASS Photometric Redshift catalogue
A. Balaguera-Antolínez, M. Bilicki, E. Branchini +1
Using the almost all-sky 2MASS Photometric Redshift catalogue (2MPZ) we perform for the first time a tomographic analysis of galaxy angular clustering in the local Universe ($z<0.2…
