Radio Monitoring Campaigns of Six Strongly Lensed Quasars
N. Rumbaugh, C. D. Fassnacht, J. P. McKean +3
We observed six strongly lensed, radio-loud quasars (MG 0414+0534, CLASS B0712+472, JVAS B1030+074, CLASS B1127+385, CLASS B1152+199, and JVAS B1938+666) in order to identify syste…
Measuring gravitational lens time delays using low-resolution radio monitoring observations
G. Gurkan, N. Jackson, L. V. E. Koopmans +2
Obtaining lensing time delay measurements requires long-term monitoring campaigns with a high enough resolution (< 1 arcsec) to separate the multiple images. In the radio, a limite…
Constraining the epoch of reionization with the variance statistic: simulations of the LOFAR case
Ajinkya H. Patil, Saleem Zaroubi, Emma Chapman +27
Several experiments are underway to detect the cosmic redshifted 21-cm signal from neutral hydrogen from the Epoch of Reionization (EoR). Due to their very low signal-to-noise rati…
