Abstract (from CDS):

We present an analysis of weak-lensing observations for RX J1347-1145 over a 43'x43' field taken in B and R filters on the Blanco 4 m telescope at CTIO. RX J1347-1145 is a massive cluster at redshift z=0.45. Using a population of galaxies with 20<R<26, we detect a weak-lensing signal at the p<0.0005 level, finding best-fit parameters of σ_v=1400⁺¹³⁰_–140 km/s for a singular isothermal sphere model and r₂₀₀=3.5^+0.8_–0.2 Mpc with c=15⁺⁶⁴_–10for an NFW model in an Ω_m=0.3, Ω_Λ=0.7 cosmology. In addition, a mass-to-light ratio M/L_R=90±20 M_☉/L_R☉_was determined. These values are consistent with the previous weak-lensing study of RX J1347-1145 by Fischer & Tyson, giving strong evidence that systemic bias was not introduced by the relatively small field of view in that study. Our best-fit parameter values are also consistent with recent X-ray studies by Allen et al. and Ettori et al. but are not consistent with recent optical velocity dispersion measurements by Cohen & Kneib.
