Two strong-lensing clusters confront universal dark-matter profiles
P. Saha, J. I. Read, L. L. R. Williams
In the galaxy clusters SSDS J1004+411 and ACO 1689, a large number of multiply-imaged background objects have recently been observed. We use these data to map the projected mass di…
Gravitational lensing model degeneracies: Is steepness all-important?
P. Saha, L. L. R. Williams
In gravitational lensing, steeper mass profiles generically produce longer time delays but smaller magnifications, without necessarily changing the image positions or magnification…
The Hubble time inferred from 10 time-delay lenses
P. Saha, J. Coles, A. V. Maccio' +1
We present a simultaneous analysis of 10 galaxy lenses having time-delay measurements. For each lens we derive a detailed free-form mass map, with uncertainties, and with the addit…
COSMOGRAIL: the COSmological MOnitoring of GRAvItational Lenses IV. Models of prospective time-delay lenses
P. Saha, F. Courbin, D. Sluse +2
Aims: To predict time delays for a sample of gravitationally lensed quasars and to evaluate the accuracy that can be realistically achieved on the value of H_0. Methods: We conside…
