Lyman-alpha Forest Constraints on Decaying Dark Matter
Mei-Yu Wang, Rupert A. C. Croft, Annika H. G. Peter +2
We present an analysis of high-resolution N-body simulations of decaying dark matter cosmologies focusing on the statistical properties of the transmitted Lyman-alpha forest flux i…
Observational Requirements for Lyman-alpha Forest Tomographic Mapping of Large-Scale Structure at z ~ 2
Khee-Gan Lee, Joseph F. Hennawi, Martin White +2
The z > 2 Lyman-alpha (Lya) forest traces the underlying dark-matter distribution on large scales and, given sufficient sightlines, can be used to create 3D maps of large-scale str…
The one-dimensional Ly-alpha forest power spectrum from BOSS
Nathalie Palanque-Delabrouille, Christophe Yèche, Arnaud Borde +33
We have developed two independent methods to measure the one-dimensional power spectrum of the transmitted flux in the Lyman- forest. The first method is based on a Fourier tran…
Gravitational redshifts from large-scale structure
Rupert A. C. Croft
The recent measurement of the gravitational redshifts of galaxies in galaxy clusters by Wojtak et al. has opened a new observational window on dark matter and modified gravity. By…
Fitting Methods for Baryon Acoustic Oscillations in the Lyman-α Forest Fluctuations in BOSS Data Release 9
David Kirkby, Daniel Margala, Anže Slosar +22
We describe fitting methods developed to analyze fluctuations in the Lyman-α forest and measure the parameters of baryon acoustic oscillations (BAO). We apply our methods to BOSS D…
Measurement of Baryon Acoustic Oscillations in the Lyman-alpha Forest Fluctuations in BOSS Data Release 9
Anže Slosar, Vid Iršič, David Kirkby +41
We use the Baryon Oscillation Spectroscopic Survey (BOSS) Data Release 9 (DR9) to detect and measure the position of the Baryonic Acoustic Oscillation (BAO) feature in the three-di…
