Growing a 'cosmic beast': observations and simulations of MACS J0717.5+3745

Jean-Paul Richard Kneib, David Richard Harvey, Barney Frederick Drake, Mathilde Jauzac, Matthieu Schaller, Matthew Aaron Robertson, Elena Cristina Dalla Vecchia, Richard Massey

We present a gravitational lensing and X-ray analysis of a massive galaxy cluster and its surroundings. The core of MACS J0717.5+3745 (M(R < 1Mpc) similar to 2 x 10(15) M-circle dot, z = 0.54) is already known to contain four merging components. We show th ...

Mapping substructure in the HST Frontier Fields cluster lenses and in cosmological simulations

Jean-Paul Richard Kneib, Hakim Atek, Mathilde Jauzac, Johan Richard, Cristina Popa

We map the lensing-inferred substructure in the first three clusters observed by the Hubble Space Telescope Frontier Fields (HSTFF) Initiative: Abell 2744 (z = 0.308), MACSJ 0416, (z = 0.396) and MACSJ 1149 (z = 0.543). Statistically resolving dark matter ...

A test for skewed distributions of dark matter, and a possible detection in galaxy cluster Abell 3827

Frédéric Courbin, David Richard Harvey, Rémy Elie Joseph, Mathilde Jauzac, Richard Massey

Simulations of self-interacting dark matter predict that dark matter should lag behind galaxies during a collision. If the interaction is mediated by a high-mass force carrier, the distribution of dark matter can also develop asymmetric dark matter tails. ...

Abell 2744: too much substructure for Lambda CDM?

David Richard Harvey, Mathilde Jauzac, Richard Massey

The massive substructures found in Abell 2744 by Jauzac et al. present a challenge to the cold dark matter paradigm due to their number and proximity to the cluster centre. We use one of the biggest N-body simulations, the Millennium XXL, to investigate th ...

Strong-lensing analysis of MACSJ0717.5+3745 from Hubble Frontier Fields observations: How well can the mass distribution be constrained?

Jean-Paul Richard Kneib, Hakim Atek, Benjamin Yvan Alexandre Clement, Markus Rexroth, Mathilde Jauzac, Johan Richard

We present a strong-lensing analysis of MACSJ0717.5+3745 (hereafter MACS J0717), based on the full depth of the Hubble Frontier Field (HFF) observations, which brings the number of multiply imaged systems to 61, ten of which have been spectroscopically con ...

Hubble Frontier Fields: predictions for the return of SN Refsdal with the MUSE and GMOS spectrographs

Jean-Paul Richard Kneib, Hakim Atek, Benjamin Yvan Alexandre Clement, Markus Rexroth, Mathilde Jauzac, Richard Massey, Johan Richard

We present a high-precision mass model of the galaxy cluster MACS J1149.6+ 2223, based on a strong gravitational lensing analysis of Hubble Space Telescope Frontier Fields (HFF) imaging data and spectroscopic follow-up with Gemini/Gemini Multi-Object Spect ...
