Fisher Matrices and Confidence Ellipses: A Quick-Start Guide and Software
Dan Coe
Fisher matrices are used frequently in the analysis of combining cosmological constraints from various data sets. They encode the Gaussian uncertainties of multiple variables. They…
Detailed dark matter maps of galaxy cluster substructure and direct comparison to simulations
Dan Coe
Images from the next generation of telescopes will enable strikingly detailed reconstruction of the dark matter distributions in galaxy cluster cores using strong gravitational len…
Strong gravitational lensing probes of the particle nature of dark matter
Leonidas A. Moustakas, Kevork Abazajian, Andrew Benson +44
There is a vast menagerie of plausible candidates for the constituents of dark matter, both within and beyond extensions of the Standard Model of particle physics. Each of these ca…
New Multiply-Lensed Galaxies Identified in ACS/NIC3 Observations of Cl0024+1654 Using an Improved Mass Model
Adi Zitrin, Tom Broadhurst, Keiichi Umetsu +9
We present an improved strong-lensing analysis of Cl0024+1654 (=0.39) using deep HST/ACS/NIC3 images, based on 33 multiply-lensed images of 11 background galaxies. These are fou…
