Dissection of the collisional and collisionless mass components in a mini sample of CLASH and HFF massive galaxy clusters at
M. Bonamigo, C. Grillo, S. Ettori +7
We present a multi-wavelength study of the massive (-) galaxy clusters RXC J2248.74431, MACS J0416.12403, and MACS J120…
Mass profile decomposition of the Frontier Fields cluster MACS J0416-02403. Insights on the Dark-Matter inner profile
M. Annunziatella, M. Bonamigo, C. Grillo +8
We present a high resolution dissection of the two-dimensional total mass distribution in the core of the Hubble Frontier Fields galaxy cluster MACS J0416.1-2403, at z ~ 0.396. We…
The mass dependence of dark matter halo alignments with large-scale structure
Davide Piras, Benjamin Joachimi, Björn Malte Schäfer +3
Tidal gravitational forces can modify the shape of galaxies and clusters of galaxies, thus correlating their orientation with the surrounding matter density field. We study the dep…
Mass distribution in the core of MACS J1206: robust modeling from an exceptionally large sample of central multiple images
G. B. Caminha, C. Grillo, P. Rosati +24
We present a new strong lensing analysis of the galaxy cluster MACS J1206.2-0847 (MACS 1206), at z=0.44, using deep spectroscopy from CLASH-VLT and VLT/MUSE archival data in combin…
Joining X-ray to lensing: an accurate combined analysis of MACS J0416.12403
M. Bonamigo, C. Grillo, S. Ettori +6
We present a novel approach for a combined analysis of X-ray and gravitational lensing data and apply this technique to the merging galaxy cluster MACS J0416.12403. The method e…
Discovery and first models of the quadruply lensed quasar SDSS J1433+6007
Adriano Agnello, Claudio Grillo, Tucker Jones +3
We report the discovery of the quadruply lensed quasar J1433+6007, mined in the SDSS DR12 photometric catalogues using a novel outlier-selection technique, without prior spectrosco…
A look to the inside of haloes: a characterisation of the halo shape as a function of overdensity in the Planck cosmology
Giulia Despali, Carlo Giocoli, Mario Bonamigo +2
In this paper we study the triaxial properties of dark matter haloes of a wide range of masses extracted from a set of cosmological N-body simulations. We measure the shape at diff…
Characterising Strong Lensing Galaxy Clusters using the Millennium-XXL and MOKA simulations
Carlo Giocoli, Mario Bonamigo, Marceau Limousin +5
In this paper we investigate the strong lensing statistics in galaxy clusters. We extract dark matter haloes from the Millennium-XXL simulation, compute their Einstein radius distr…
Strong-Lensing Analysis of MACS,J0717.5+3745 from Hubble Frontier Fields observations: How well can the mass distribution be constrained?
M. Limousin, J. Richard, E. Jullo +12
[abridged] We present a strong-lensing analysis of MACSJ0717.5+3745, based on the full depth of the Hubble Frontier Field (HFF) observations, which brings the number of multiply im…
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…
