Galaxy Merger Statistics and Inferred Bulge-to-Disk Ratios in Cosmological SPH Simulations
Ariyeh Maller, Neal Katz, Dusan Keres +2
We construct merger trees for galaxies identified in a cosmological hydrodynamical simulation and use them to characterize predicted merger rates as a function of redshift, galaxy…
Probing Galaxy Formation with He II Cooling Lines
Yujin Yang, Ann I. Zabludoff, Romeel Davé +5
Using high resolution cosmological simulations, we study hydrogen and helium gravitational cooling radiation. We focus on the HeII cooling lines, which arise from gas with a differ…
The Physical and Photometric Properties of High-Redshift Galaxies in Cosmological Hydrodynamic Simulations
K. Finlator, R. Dave, C. Papovich +1
We study the physical and photometric properties of galaxies at z=4 in cosmological hydrodynamic simulations of a lambda-CDM universe. We focus on galaxies satisfying the GOODS "B-…
Lyman Alpha Flux Power Spectrum and Its Covariance
Hu Zhan, Romeel Dave, Daniel Eisenstein +1
We analyze the flux power spectrum and its covariance using simulated Lyman alpha forests. We find that pseudo-hydro techniques are good approximations of hydrodynamical simulation…
Measuring the Halo Mass of z=3 Damped Ly-alpha Absorbers from the Absorber-Galaxy Cross-correlation
Nicolas Bouche, Jeffrey P. Gardner, David H. Weinberg +3
[Abridged] We test the reliability of a method to measure the mean halo mass of Damped Ly-alpha absorbers (DLAs). The method is based on measuring the ratio of the cross-correlatio…
