High detection significance of the dark substructure in gravitational lens SDSSJ0946+1006 by image pixel supersampling
Quinn E. Minor
Recent studies have shown that the dark substructure reported in the gravitational lens SDSSJ0946+1006 has a high central density which is in apparent tension with the CDM parad…
A Stringent Upper Limit on Dark Matter Self-Interaction Cross Section from Cluster Strong Lensing
Kevin E. Andrade, Jackson Fuson, Sophia Gad-Nasr +4
We analyze strongly lensed images in 8 galaxy clusters to measure their dark matter density profiles in the radial region between 10 kpc and 150 kpc, and use this to constrain the…
Inferring the concentration of dark matter subhalos perturbing strongly lensed images
Quinn E. Minor, Manoj Kaplinghat, Tony H. Chan +1
We demonstrate that the perturbations of strongly lensed images by low-mass dark matter subhalos are significantly impacted by the concentration of the perturbing subhalo. For subh…
An unexpected high concentration for the dark substructure in the gravitational lens SDSSJ0946+1006
Quinn E. Minor, Sophia Gad-Nasr, Manoj Kaplinghat +1
The presence of an invisible substructure has previously been detected in the gravitational lens galaxy SDSSJ0946+1006 through its perturbation of the lensed images. Using flexible…
Detecting Dark Matter Cores in Galaxy Clusters with Strong Lensing
Kevin E. Andrade, Quinn Minor, Anna Nierenberg +1
We test the ability of strong lensing data to constrain the size of a central core in the dark matter halos of galaxy clusters, using Abell 611 as a prototype. Using simulated data…
Robust velocity dispersion and binary population modeling of the ultra-faint dwarf galaxy Reticulum II
Quinn E. Minor, Andrew B. Pace, Jennifer L. Marshall +1
We apply a Bayesian method to model multi-epoch radial velocity measurements in the ultra-faint dwarf galaxy Reticulum II, fully accounting for the effects of binary orbital motion…
