Title: Lyman alpha forest in 1D and 3D
Date: Wednesday, February 13th, 2013
Time: 11:30
Venue: Villa Bazzoni

Abstract While we have seen many measurements of the Lyman alpha forest in the last
decade in the form of 1D power spectrum there have been several
suggestions how to expand its applicability. One of them is extending the
measurements to 3D correlation function and thus help constrain the BAO
scale. The other is to explore the cross-correlations with higher order
Lyman series. In this talk I will present the results of one of the first
BAO peak detections in Lyman alpha forest using the 3D mapping of the
intergalactic medium with quasars line-of-sights. Finally I will show
preliminary results on the 1D Lyman beta forest power spectrum
measurements.
