Core Mass Estimates in Strong Lensing Galaxy Clusters: a Comparison Between Masses Obtained from Detailed Lens Models, Single-Halo Lens Models, and Einstein Radii
J. D. Remolina González, K. Sharon, G. Mahler +7
The core mass of galaxy clusters is both an important anchor of the radial mass distribution profile and probe of structure formation. With thousands of strong lensing galaxy clust…
The BUFFALO HST Survey
Charles L. Steinhardt, Mathilde Jauzac, Ana Acebron +91
The Beyond Ultra-deep Frontier Fields and Legacy Observations (BUFFALO) is a 101 orbit + 101 parallel Cycle 25 Hubble Space Telescope Treasury program taking data from 2018-2020. B…
Strong Lensing Model of SPT-CLJ0356-5337, a Major Merger Candidate at Redshift 1.0359
Guillaume Mahler, Keren Sharon, Michael D. Gladders +10
We present an analysis of the mass distribution inferred from strong lensing by SPT-CL J0356-5337, a cluster of galaxies at redshift z = 1.0359 revealed in the follow-up of the SPT…
Strong Lens Models for 37 Clusters of Galaxies from the SDSS Giant Arcs Survey
Keren Sharon, Matthew B. Bayliss, Håkon Dahle +12
We present strong gravitational lensing models for 37 galaxy clusters from the SDSS Giant Arcs Survey. We combine data from multi-band Hubble Space Telescope WFC3imaging, with grou…
