Universality of dark matter haloes shape over six decades in mass: Insights from the Millennium XXL and SBARBINE simulations
Mario Bonamigo, Giulia Despali, Marceau Limousin +3
For the last 30 years many observational and theoretical evidences have shown that galaxy clusters are not spherical objects, and that their shape is much better described by a tri…
On the Effects of Line-of-Sight Structures on Lensing Flux-ratio Anomalies in a LCDM Universe
D. D. Xu, Shude Mao, Andrew Cooper +4
The flux-ratio anomalies observed in multiply-lensed quasar images are most plausibly explained as the result of perturbing structures superposed on the underlying smooth matter di…
A Lightcone Catalogue from the Millennium-XXL Simulation
Alex Smith, Shaun Cole, Carlton Baugh +4
Future galaxy surveys require realistic mock catalogues to understand and quantify systematics in order to make precise cosmological measurements. We present a halo lightcone catal…
Very Massive Tracers and Higher Derivative Biases
Tomohiro Fujita, Valentin Mauerhofer, Leonardo Senatore +2
Most of the upcoming cosmological information will come from analyzing the clustering of the Large Scale Structures (LSS) of the universe through LSS or CMB observations. It is the…
Detection of a universal core-halo transition in dwarf galaxies as predicted by Bose-Einstein dark matter
Alvaro Pozo, Tom Broadhurst, Ivan de Martino +4
The presence of large dark matter cores in dwarf galaxies has long been puzzling and many are now known to be surrounded by an extensive halo of stars. Distinctive core-halo struct…
Exploring the non-linear density field in the Millennium simulations with tessellations - I. The probability distribution function
Biswajit Pandey, Simon D. M. White, Volker Springel +1
We use the Delaunay Tessellation Field Estimator (DTFE) to study the one-point density distribution functions of the Millennium (MS) and Millennium-II (MS-II) simulations. The DTFE…
Numerical Simulations of the Dark Universe: State of the Art and the Next Decade
Michael Kuhlen, Mark Vogelsberger, Raul Angulo
We present a review of the current state of the art of cosmological dark matter simulations, with particular emphasis on the implications for dark matter detection efforts and stud…
A flexible subhalo abundance matching model for galaxy clustering in redshift space
Sergio Contreras, Raul Angulo, Matteo Zennaro
We develop an extension of subhalo abundance matching (SHAM) capable of accurately reproducing the real and redshift-space clustering of galaxies in a state-of-the-art hydrodynamic…
Galaxy formation in the Planck Cosmology - I. Matching the observed evolution of star formation rates, colours and stellar masses
Bruno Henriques, Simon White, Peter Thomas +5
We have updated the Munich galaxy formation model to the Planck first-year cosmology, while modifying the treatment of baryonic processes to reproduce recent data on the abundance…
Simulations of the galaxy population constrained by observations from z=3 to the present day: implications for galactic winds and the fate of their ejecta
Bruno Henriques, Simon White, Peter Thomas +4
We apply Monte Carlo Markov Chain (MCMC) methods to large-scale simulations of galaxy formation in a LambdaCDM cosmology in order to explore how star formation and feedback are con…
SHAMe-SF: Predicting the clustering of star-forming galaxies with an enhanced abundance matching model
Sara Ortega-Martinez, Sergio Contreras, Raul Angulo
With the advent of several galaxy surveys targeting star-forming galaxies, it is important to have models capable of interpreting their spatial distribution in terms of astrophysic…
On the Statistics of Biased Tracers in the Effective Field Theory of Large Scale Structures
Raul Angulo, Matteo Fasiello, Leonardo Senatore +1
With the completion of the Planck mission, in order to continue to gather cosmological information it has become crucial to understand the Large Scale Structures (LSS) of the unive…
Evidence of Neutrino Enhanced Clustering in a Complete Sample of Sloan Survey Clusters, Implying eV
Razieh Emami, Tom Broadhurst, Pablo Jimeno +7
The clustering amplitude of 7143 clusters from the Sloan Digital Sky Survey (SDSS) is found to increase with cluster mass, closely agreeing with the Gaussian random field hypothesi…
Low-redshift constraints on structure growth from CMB lensing tomography
Andrea Rubiola, Matteo Zennaro, Carlos GarcÃa-GarcÃa +2
We present constraints on the amplitude of matter fluctuations from the clustering of galaxies and their cross-correlation with the gravitational lensing convergence of the cosmic…
Precise Clustering and Density Evolution of redMaPPer Galaxy Clusters versus MXXL Simulation

A flexible modelling of galaxy assembly bias
Sergio Contreras, Raul Angulo, Matteo Zennaro
We use the {\sc Illustris TNG300} magneto-hydrodynamic simulation, the {\sc SAGE} semi-analytical model, and the subhalo abundance matching technique (SHAM) to examine the diversit…
What is the best way to measure baryonic acoustic oscillations?
Ariel G. Sanchez, Carlton M. Baugh, Raul Angulo
Oscillations in the baryon-photon fluid prior to recombination imprint different signatures on the power spectrum and correlation function of matter fluctuations. The measurement o…
