The Growth of Central and Satellite Galaxies in Cosmological Smoothed Particle Hydrodynamics Simulations
Vimal Simha, David H. Weinberg, Romeel Dave +3
We examine the accretion and merger histories of central and satellite galaxies in a smoothed particle hydrodynamics (SPH) cosmological simulation that resolves galaxies down to 7e…
Galaxies in a simulated CDM Universe I: cold mode and hot cores
Dušan Kereš, Neal Katz, Mark Fardal +2
We study the formation of galaxies in a (50 Mpc/h)^3 cosmological simulation (2x288^3 particles), evolved using the entropy conserving SPH code Gadget-2. Most of the baryonic mass…
A New Moment Method for Continuum Radiative Transfer in Cosmological Reionization
K. Finlator, F. Ozel, R. Dave
We introduce a new code for computing time-dependent continuum radiative transfer and non-equilibrium ionization states in static density fields with periodic boundaries. Our code…
The Flux Auto- and Cross-Correlation of the Lyman-alpha Forest. II. Modelling Anisotropies with Cosmological Hydrodynamic Simulations
Andrew R. Marble, Kristoffer A. Eriksen, Chris D. Impey +2
The isotropy of the Lyman-alpha forest in real-space uniquely provides a measurement of cosmic geometry at z > 2. The angular diameter distance for which the correlation function a…
Molecular Star Formation Rate Indicators in Galaxies
Desika Narayanan, Thomas J. Cox, Yancy Shirley +3
We derive a physical model for the observed relations between star formation rate (SFR) and molecular line (CO and HCN) emission in galaxies, and show how these observed relations…
The Role of Galactic Winds on Molecular Gas Emission from Galaxy Mergers
Desika Narayanan, T. J. Cox, Brandon Kelly +7
We assess the impact of starburst and AGN feedback-driven winds on the CO emission from galaxy mergers, and, in particular, search for signatures of these winds in the simulated CO…
