Warm Dark Matter: Clues to Primordial Phase Density from the Structure of Galaxy Halos
Craig J. Hogan
The Cold Dark Matter paradigm successfully explains many phenomena on scales larger than galaxies, but seems to predict galaxy halos which are more centrally concentrated and have…
Energy Flow in the Universe
Craig J. Hogan
A brief but broad survey is presented of the flows, forms and large-scale transformations of mass-energy in the universe, spanning a range of about twenty orders of magnitude (m_{P…
Where the Baryons Are
Craig J. Hogan
A fair and complete accounting of cosmic baryons now appears possible, because most of them are in states which are either directly observable or reliably constrained by indirect a…
Measuring Omega Baryon from the Helium Lyman-Alpha Forest
James W. Wadsley, Craig J. Hogan, Scott F. Anderson
A new method to extract Omega_b from high redshift intergalactic absorption is described, based on the distribution of HeII Ly-alpha optical depths in the voids in the ionization z…
A Java Calculator of Standard Big Bang Nucleosynthesis
Luis Mendoza, Craig J. Hogan
A simple Java applet is presented which allows quick and easy computation and plotting of the predictions of light element abundances in SBBN, including errors in the predictions p…
