The nature of a gravitationally lensed sub-millimetre arc in MS0451.6-0305: two interacting galaxies at z~2.9?
C. Borys, S. C. Chapman, M. Donahue +6
We present a new SCUBA image of the cluster MS0451.6-0305, which exhibits strong, extended sub-mm flux at 850 microns. The most striking feature in the map is an elongated region o…

Estimates of Confusion and Gravitational Lensing Limits in Sunyaev-Zel'dovich Increment Measurements
Michael Zemcov, Peter Newbury, Mark Halpern
We present estimates of the confusion limit of measurements of the Sunyaev-Zel'dovich effect (SZ) increment near its peak intensity based on Monte Carlo simulations of sub-millimet…

Reconstructions of the Strong Gravitational Lenses MS 2137 and MS 1455 Using a Two-Stage Inversion Algorithm
P. Newbury, G. G. Fahlman
We propose a new, two-stage algorithm for inverting strong gravitational lenses. The key to the algorithm is decoupling the effects of lens magnification and intrinsic structure in…
