The Lyman-continuum photon production efficiency in the high-redshift Universe
Stephen M. Wilkins, Yu Feng, Tiziana Di Matteo +4
The Lyman Continuum photon production efficiency () is a critical ingredient for inferring the number of photons available to reionise the intergalactic medium. To est…
Perturbation theory, effective field theory, and oscillations in the power spectrum
Zvonimir Vlah, Uroš Seljak, Man Yat Chu +1
We explore the relationship between the nonlinear matter power spectrum and the various Lagrangian and Standard Perturbation Theories (LPT and SPT). We first look at it in the cont…
Luminosity function of [OII] emission-line galaxies in the MassiveBlack-II simulation
KwangHo Park, Tiziana Di Matteo, Shirley Ho +4
We examine the luminosity function (LF) of [OII] emission-line galaxies in the high-resolution cosmological simulation MassiveBlack-II (MBII). From the spectral energy distribution…
Eulerian BAO Reconstructions and N-Point Statistics
Marcel Schmittfull, Yu Feng, Florian Beutler +2
As galaxy surveys begin to measure the imprint of baryonic acoustic oscillations (BAO) on large-scale structure at the sub-percent level, reconstruction techniques that reduce the…
The BlueTides Simulation: First Galaxies and Reionization
Yu Feng, Tiziana Di-Matteo, Rupert A. Croft +3
We introduce the BlueTides simulation and report initial results for the luminosity functions of the first galaxies and AGN, and their contribution to reionization. BlueTides was r…
The formation of Milky Way-mass disk galaxies in the first 500 million years of a cold dark matter universe
Yu Feng, Tiziana Di Matteo, Rupert Croft +4
Whether among the myriad tiny proto-galaxies there exists a population with similarities to present day galaxies is an open question. We show, using BlueTides, the first hydrodynam…
