Cluster Mass Profiles from a Bayesian Analysis of Weak Lensing Distortion and Magnification Measurements: Applications to Subaru Data
Keiichi Umetsu, Tom Broadhurst, Adi Zitrin +2
We directly construct model-independent mass profiles of galaxy clusters from combined weak-lensing distortion and magnification measurements within a Bayesian statistical framewor…
Strong-Lensing Analysis of MS 1358.4+6245: New Multiple Images and Implications for the Well-Resolved z=4.92 Galaxy
Adi Zitrin, Tom Broadhurst, Dan Coe +5
We present a strong-lensing analysis of the galaxy cluster MS 1358.4+6245 (), in deep 6-band ACS/HST imaging. In addition to the well-studied system at , our modell…
Quantifying the collisionless nature of dark matter and galaxies in A1689
Doron Lemze, Yoel Rephaeli, Rennan Barkana +3
We use extensive measurements of the cluster A1689 to assess the expected similarity in the dynamics of galaxies and dark matter (DM) in their motion as collisionless `particles' i…
The Highest Resolution Mass Map of Galaxy Cluster Substructure To Date Without Assuming Light Traces Mass: LensPerfect Analysis of Abell 1689
Dan Coe, Narciso Benitez, Tom Broadhurst +2
We present a strong lensing mass model of Abell 1689 which resolves substructures ~25 kpc across (including about ten individual galaxy subhalos) within the central ~400 kpc diamet…
k-essence and extended tachyons in brane-worlds
Luis P. Chimento, Martín G. Richarte
We study a k-essence field evolving linearly with the cosmic time and the atypical k-essence model on a homogeneous and isotropic flat 3-brane. We show that the k-field is driven b…
Testing Strict Hydrostatic Equilibrium in Simulated Clusters of Galaxies: Implications to Abell 1689
S. M. Molnar, I. -N. Chiu, K. Umetsu +5
Accurate mass determination of clusters of galaxies is crucial if they are to be used as cosmological probes. However, there are some discrepancies between cluster masses determine…
