Further Investigation of the Time Delay, Magnification Ratios, and Variability in the Gravitational Lens 0218+357
A. S. Cohen, J. N. Hewitt, C. B. Moore +1
High precision VLA flux density measurements for the lensed images of 0218+357 yield a time delay of 10.1(+1.5-1.6)days (95% confidence). This is consistent with independent measur…

New VLBI Constraints for 0957+561 Lens Models
Deborah Haarsma, Joseph Leh'ar, Rennan Barkana
Time-delay measurements of 0957+561 based on radio monitoring now agree with optical monitoring. Recent models incorporate many recent observations, but the systematic uncertaintie…
