Simulations of BAO reconstruction with a quasar Ly-α survey
Context. The imprint of baryonic acoustic oscillations (BAO) on the matter power spectrum can be constrained using the neutral hydrogen density in the intergalactic... -
A principal component analysis of quasar UV spectra at z ~ 3
From a principal component analysis (PCA) of 78 z ~ 3 high-quality quasar spectra in the SDSS-DR7 we derive the principal components that characterize the QSO... -
Determination of the Point-spread Function for the Fermi Large Area Telescope...
The Large Area Telescope (LAT) on the Fermi Gamma-ray Space Telescope is a pair-conversion telescope designed to detect photons with energies from ≈20 MeV to >300... -
The BOSS Lyα Forest Sample from SDSS Data Release 9
We present the BOSS Lyman-α (Lyα) Forest Sample from SDSS Data Release 9, comprising 54,468 quasar spectra with z qso > 2.15 suitable for Lyα forest analysis. This...
