Time delay for the gravitational lens system B0218+357


Abstract

There are now a total of 5 gravitational lens systems with measured time delays. What's interesting about 0218, apart from the fact that it is in some sense the ideal system for this type of work, is that we have obtained consistent delays from simultaneous observations of flux density, percentage polarisation and polarisation position angle variations at different frequencies. You can get the data used to make the figures from here. With time, I hope to make all data from my papers available which are necessary to reproduce the results.

The links below point to one file containing the complete text, all figures and tables etc.

As are most of my publications this is available in more than one form:
