Cosmological implications of Lyman-break galaxy clustering [PDF]

open access: yesThe 9th astrophysics conference: After the dark ages, when galaxies were young (the Universe at 2<Z<5), 1999
We review our analysis of the clustering properties of ``Lyman-break'' galaxies (LBGs) at redshift z~3, previously discussed in Wechsler et al (1998). We examine the likelihood of spikes found by Steidel et al (1998) in the redshift distribution of LBGs, within a suite of models for the evolution of structure in the Universe.

Winds and infalling gas in Lyman break galaxies [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2006
A model for gas outflows is proposed which simultaneously explains the correlations between the (i) equivalent width of low ionization and Ly-alpha lines, (ii) outflow velocity, and (iii) star formation rate observed in Lyman Break Galaxies (LBGs).

Lyman Break Galaxies: Their Progenitors and Descendants [PDF]

open access: yesThe Astrophysical Journal, 2002
We study the evolution of Lyman Break Galaxies (LBGs) from z=5 to z=0 by tracing the merger trees of galaxies in a large-scale hydrodynamic simulation based on a Lambda cold dark matter model. In particular, we emphasize on the range of properties of the sample selected by the rest-frame V band luminosity, in accordance with recent near-IR observations.

Lyman-continuum galaxies and the escape fraction of Lyman-break galaxies [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2014
Lyman-break galaxies (LBGs) at z ̃ 3-4 are targeted to measure the fraction of Lyman-continuum (LyC) flux that escapes from high-redshift galaxies. However, z ̃ 3-4 LBGs are identified using the Lyman-break technique which preferentially selects galaxies with little or no LyC.

The Environmental Impact of Lyman Break Galaxies

open access: yesThe Astrophysical Journal, 2006
We perform cosmological simulations of galaxies forming at z=3 using the hydrodynamics grid code, Enzo. By selecting the largest galaxies in the volume to correspond to Lyman-break galaxies, we construct observational spectra of the HI flux distribution around these objects, as well as column densities of CIV and OVI throughout a refined region.

Lyman Break Galaxies and the Lyα Forest [PDF]

open access: yesThe Astrophysical Journal, 2003
We use hydrodynamic cosmological simulations to predict correlations between Lyα forest absorption and the galaxy distribution at redshift z ≈ 3. The probability distribution function (PDF) of Lyα flux decrements shifts systematically toward higher values in the vicinity of galaxies, reflecting the overdense environments in which these galaxies reside.

On the Spatial Correlations of Lyman Break Galaxies [PDF]

open access: yesThe Astrophysical Journal, 2003
Motivated by the observed discrepancy between the strong spatial correlations of Lyman break galaxies (LBGs) and their velocity dispersions, we consider a theoretical model in which these starbursting galaxies are associated with dark matter halos that experience appreciable infall of material.
