The theme of the 2005 LBL cosmology summer visitor program is Precision
Cosmology with the Lyman-alpha Forest. The Lyman-alpha forest has
emerged as an important cosmological tool and has already provided
constraints on cosmological parameters, such as the neutrino mass and
the primordial tilt of the power spectrum, which rival the precision of
the CMB and large galaxy surveys. Future samples of quasar pairs will
provide a means to measure the dark energy density at z ~ 2, through
the Alcock-Paczynksi test.
In the past few years the quantity and quality of data available has grown
enormously. Combined with the advances in numerical methods and
progress in related areas, it is timely to assess which aspects of the Lyman
Alpha Forest hold the most promise for current issues in cosmology.
We anticipate mostly unstructured interactions following the Aspen philosophy, with short technical talks in the morning and then a daily afternoon tea with informal discussions.
