Sub-mm Galaxies in Cosmological Simulations
Mark A. Fardal, Neal Katz, David H. Weinberg +2
We study the predicted sub-mm emission from massive galaxies in a Lambda-CDM universe, using hydrodynamic cosmological simulations. Assuming that most of the emission from newly fo…
HST observations of NGC 6240
J. Gerssen, R. P. van der Marel, D. Axon +3
WFPC2 images and STIS spectroscopic observations are presented of the double nucleus in the merger system NGC 6240. We find that: (a) the kinematics of the ionized gas is similar t…
Evolution of Clustering and Bias in a Lambda-CDM Universe
Romeel Davé, Lars Hernquist, Neal Katz +1
We determine the evolution from of the galaxy and mass correlation functions and bias factor in a Mpc CDM hydrodynamic simulation with kpc resolut…
The Nature of Lyman Break Galaxies in Cosmological Hydrodynamic Simulations
Romeel Davé, Jeffrey P. Gardner, Lars Hernquist +2
What type of objects are being detected as "Lyman break galaxies"? Are they predominantly the most massive galaxies at that epoch, or are many of them smaller galaxies un…
Theoretical Modeling of the High Redshift Galaxy Population
David H. Weinberg, Romeel Dave', Jeffrey P. Gardner +2
We review theoretical approaches to the study of galaxy formation, with emphasis on the role of hydrodynamic simulations in modeling the high redshift galaxy population. We present…
Cosmology with the Lyman-alpha Forest
David H. Weinberg, Scott Burles, Rupert A. C. Croft +11
We outline the physical picture of the high-redshift Ly-alpha forest that has emerged from cosmological simulations, describe statistical characteristics of the forest that can be…
