Near-IR Weak-Lensing (NIRWL) Measurements in the CANDELS Fields I: Point-Spread Function Modeling and Systematics
Kyle Finner, Bomee Lee, Ranga-Ram Chary +5
We have undertaken a Near-IR Weak Lensing (NIRWL) analysis of the wide-field CANDELS HST/WFC3-IR F160W observations. With the Gaia proper-motion-corrected catalog as an astrometric…
Dark matter dynamics in Abell 3827: new data consistent with standard Cold Dark Matter
Richard Massey, David Harvey, Jori Liesenborgs +23
We present integral field spectroscopy of galaxy cluster Abell 3827, using ALMA and VLT/MUSE. It reveals an unusual configuration of strong gravitational lensing in the cluster cor…
A test for skewed distributions of dark matter and a possible detection in galaxy cluster Abell 3827
Peter Taylor, Richard Massey, Mathilde Jauzac +4
Simulations of self-interacting dark matter (SIDM) predict that dark matter should lag behind galaxies during a collision. If the interaction is mediated by a high-mass force carri…
The Extraordinary Amount of Substructure in the Hubble Frontier Fields Cluster Abell 2744
M. Jauzac, D. Eckert, J. Schwinn +21
We present a joint optical/X-ray analysis of the massive galaxy cluster Abell 2744 (z=0.308). Our strong- and weak-lensing analysis within the central region of the cluster, i.e.,…
