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.
