Cosmological dark matter annihilations into γ rays : a closer look (2002)
Journal Article
Ullio, P., Bergström, L., Edsjö, J., & Lacey, C. (2002). Cosmological dark matter annihilations into γ rays : a closer look. Physical Review D, 66(12), Article 123502. https://doi.org/10.1103/physrevd.66.123502

We investigate the prospects of detecting weakly interacting massive particle (WIMP) dark matter by measuring the contribution to the extragalactic gamma-ray radiation induced, in any dark matter halo and at all redshifts, by WIMP pair annihilations...

Statistics of neutral regions during hydrogen reionization (2002)
Journal Article
Nusser, A., Benson, A., Sugiyama, N., & Lacey, C. (2002). Statistics of neutral regions during hydrogen reionization. Astrophysical Journal Letters, 580(2), L93-L96. https://doi.org/10.1086/345655

We present predictions for two statistical measures of the hydrogen reionization process at high redshift. The first statistic is the number of neutral segments identified in spectra of high-redshift QSOs as a function of their length. The second is...

The effects of photoionization on galaxy formation - II. Satellite galaxies in the Local Group (2002)
Journal Article
Benson, A., Frenk, C., Lacey, C., Baugh, C., & Cole, S. (2002). The effects of photoionization on galaxy formation - II. Satellite galaxies in the Local Group. Monthly Notices of the Royal Astronomical Society, 333(1), 177-190. https://doi.org/10.1046/j.1365-8711.2002.05388.x

We use a self-consistent model of galaxy formation and the evolution of the intergalactic medium to study the effects of the reionization of the Universe at high redshift on the properties of satellite galaxies like those seen around the Milky Way. P... Read More about The effects of photoionization on galaxy formation - II. Satellite galaxies in the Local Group.

The effects of photoionization on galaxy formation - I. Model and results at z=0 (2002)
Journal Article
Benson, A., Lacey, C., Baugh, C., Cole, S., & Frenk, C. (2002). The effects of photoionization on galaxy formation - I. Model and results at z=0. Monthly Notices of the Royal Astronomical Society, 333(1), 156-176. https://doi.org/10.1046/j.1365-8711.2002.05387.x

We develop a coupled model for the evolution of the global properties of the intergalactic medium (IGM) and the formation of galaxies, in the presence of a photoionizing background due to stars and quasars. We use this model to predict the thermodyna... Read More about The effects of photoionization on galaxy formation - I. Model and results at z=0.
