    Gravitational Lensing
    from 31 Jul 2006 through 4 Aug 2006


Mornings will be devoted to talks; in the afternoons there is time to work on the questions to be defined on day 1.


Roger has suggested the following questions as issues we can work on. We will discuss these on Monday, and refine them into topics to study during the week.


  1. Have we discovered dark matter substructure and does it confirm numerical



  1. How well can strong lenses measure the Hubble constant?


  1. What are the practical limitations to using weak lensing to studying dark



  1. Do we really understand clusters well enough to use them for cosmological



  1. Can we use microlensing to learn about quasar accretion disks?
