The Opacity of the Lyman Alpha Forest and Implications for Ωbaryon and the Ionizing Background
We have measured the distribution function of the flux decrement D = e−τ caused by Lyα forest absorption from intervening gas in the lines of sight to high redshift QSOs from a sample of seven high resolution QSO spectra obtained with the Keck telescope. The observed flux decrement distribution function (FDDF) is compared to the FDDF from two simulations of the Lyα forest: a ΛCDM model (with Ω ...
متن کاملExplaining the Lyman-alpha forest
It is shown that many properties of Lyα forest absorbers can be derived using simple physical arguments. Analytical expressions are derived for the density and the size of an absorber as a function of its neutral hydrogen column density, which agree well with both observations and hydrodynamical simulations. An expression is presented to compute ΩIGM from the observed column density distributio...
متن کاملLyman Alpha Absorber Correlations and the Bias of the Lyman Alpha Forest
Lyα absorber correlations contain information about the underlying density distribution associated with a particular class of absorbers. As such, they provide an opportunity to independently measure the “bias” of the Lyman alpha forest, i.e. the relationship between H I column density and underlying dark matter density. In these proceedings we use hydrodynamic simulations to investigate whether...
متن کاملImaging the Lyman-alpha Forest
We show that it is now possible to image optically thick Ly clouds in uores-cent Ly emission with a relatively long (20 hr) integration on a large (10 m) telescope. For a broad range of column densities (N > 10 18:5 cm 2), the ux of Ly photons from recombination cascades is equal to 0:6 times the ux of ionizing photons, independent of the geometry of the cloud. Additional Ly photons are produce...
متن کاملBackground Modeling using Perception-based Local Pattern
Background modeling is an important issue in video surveillance. A sophisticated and adaptive background model can be used to detect moving objects which are segregated from the scene in each image frame of the video via the background subtraction process. Many background subtraction methods are proposed for video acquired by a stationary camera, assuming that the background exhibits stationary...
