Three decades of gravitational lenses

Symposium at the JENAM, 21-23 April 2009

Dedicated to the memory of Sjur Refsdal, 1935 - 2009 [Sjur Refsdal]

[POSS plate of the first lens 0957+561] Since the discovery of the first gravitational lens in 1979, gravitational lensing has rapidly exploded into three fields: strong, micro, and weak lensing with applications in virtually every area in astrophysics. This symposium celebrated the 30th anniversary of the first discovery and the tremendous advance of the field in the three decades since then. It brought together all three branches of the European lensing community to review the initial theoretical ideas and observational discoveries, the progress made in theory and observations, and to discuss recent developments and directions for the future.

The symposium comprised a balance of contributions from strong, micro and weak lensing. It offered the opportunity to bring the diversified sub-fields into even closer contact again to foster coordinated efforts, which are essential to utilise the opportunities of emerging instruments and tools.
