The Signatures of Large-scale Temperature Fluctuations in the Lyman-alpha Forest
Large-scale Temperature Fluctuations the Lyman-alpha Forest
2011/1/11
It appears inevitable that reionization processes would have produced large-scale temperature fluctuations in the intergalactic medium. Using toy temperature models and detailed heating histories in c...
Minimally Parametric Power Spectrum Reconstruction from the Lyman-alpha Forest
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/27
Current results from the Lyman alpha forest assume that the primordial power spectrum of density perturbations follows a simple power law form. We present the first analysis of Lyman alpha data to stu...
