"Imaging Dark Matter with
Gravitational Lensing"
Liliya
L. R. Williams
Astronomy
Department
Gravitational lensing has become an
indispensable part of cosmologists' tool-kit.
Lensing offers a range of different techniques that can uncover smooth
and clumpy distribution of matter, on large and small scales within galaxies
and clusters of galaxies. Comparison with observed light distribution allows
one to disentangle the relative contributions of dark and light-emitting
matter.
I will summarize the various lensing
methods, describe the recent developments, and speculate on the future of the
field.
This talk is sponsored by the American
Physical Society Women's Bureau.
