The impact of baryons on the matter power spectrum from the Horizon-AGN cosmological hydrodynamical simulation
Nora Elisa Chisari, Mark L. A. Richardson, Julien Devriendt +7
Accurate cosmology from upcoming weak lensing surveys relies on knowledge of the total matter power spectrum at percent level at scales /Mpc, for which modelling the im…
Galactic winds and stellar populations in Lyman emitting galaxies at z ~ 3.1
Emily M. McLinden, James E. Rhoads, Sangeeta Malhotra +4
We present a sample of 33 spectroscopically confirmed z ~ 3.1 Ly-emitting galaxies (LAEs) in the Cosmological Evolution Survey (COSMOS) field. This paper details the narrow-band…
Formation of Compact Clusters from High Resolution Hybrid Cosmological Simulations
Mark L. A. Richardson, Evan Scannapieco, William J. Gray
The early Universe hosted a large population of small dark matter `minihalos' that were too small to cool and form stars on their own. These existed as static objects around larger…
Hybrid Cosmological Simulations with Stream Velocities
Mark L. A. Richardson, Evan Scannapieco, Robert J. Thacker
In the early universe, substantial relative "stream" velocities between the gas and dark matter arise due to radiation pressure and persist after recombination. To asses the impact…
The Dynamical Masses, Densities, and Star Formation Scaling Relations of Lyman Alpha Galaxies
James E. Rhoads, Sangeeta Malhotra, Steven L. Finkelstein +4
We present the first dynamical mass measurements for Lyman alpha galaxies at high redshift, based on velocity dispersion measurements from rest-frame optical emission lines and siz…
First spectroscopic measurements of [OIII] emission from Lyman-alpha selected field galaxies at z ~ 3.1
Emily M. McLinden, Steven L. Finkelstein, James E. Rhoads +9
We present the first spectroscopic measurements of the [OIII] 5007 A line in two z ~ 3.1 Lyman-alpha emitting galaxies (LAEs) using the new near-infrared instrument LUCIFER1 on the…
Power spectrum for the small-scale Universe
Lawrence M. Widrow, Pascal J. Elahi, Robert J. Thacker +2
The first objects to arise in a cold dark matter universe present a daunting challenge for models of structure formation. In the ultra small-scale limit, CDM structures form nearly…
