Exploiting Low-Dimensional Structure in Astronomical Spectra
Joseph W. Richards, Peter E. Freeman, Ann B. Lee +1
Dimension-reduction techniques can greatly improve statistical inference in astronomy. A standard approach is to use Principal Components Analysis (PCA). In this work we apply a re…
Inference for the dark energy equation of state using Type IA supernova data
Christopher Genovese, Peter Freeman, Larry Wasserman +2
The surprising discovery of an accelerating universe led cosmologists to posit the existence of "dark energy"--a mysterious energy field that permeates the universe. Understanding…
The XMM Cluster Survey: Forecasting cosmological and cluster scaling-relation parameter constraints
Martin Sahlén, Pedro T. P. Viana, Andrew R. Liddle +16
We forecast the constraints on the values of sigma_8, Omega_m, and cluster scaling relation parameters which we expect to obtain from the XMM Cluster Survey (XCS). We assume a flat…
