"Baryons: What, When and Where?"
A review the current state of empirical knowledge of the total budget of baryonic matter in the Universe as observed since the epoch of reionization. Our summary examines on three milestone redshifts since the reionization of H in the IGM, z = 3, 1 and 0 with emphasis on the endpoints. We review the observational techniques used to discover and characterize the phases of baryons. In this talk, I will emphasize the open questions regarding this research, of which there are embarrassingly many. See astro-ph/0805.4635 for a write-up of this material.

"Probing the Dark Matter-Galaxy Formation Connection with Lyman Alpha Emitting Galaxies"
I will describe how our understanding of cosmological structure formation is used to probe the dark matter properties of high-redshift galaxies and to identify their present-day descendants. We studied the clustering properties and multiwavelength spectral energy distributions of a complete sample of 162 Lyman Alpha Emitting (LAE) galaxies at z=3.1 discovered in deep narrow-band imaging of the MUSYC-ECDFS field. The LAEs exhibit a moderate clustering bias of b=1.7, which implies median dark matter halo masses of 1011 M_sun. The evolution of galaxy bias with redshift predicts that z=3.1 LAEs evolve into typical present-day galaxies with L~=L*, whereas other z>3 galaxy populations, including Lyman Break Galaxies and Active Galactic Nuclei, typically evolve into more massive galaxies. A two-population fit to the LAE spectral energy distribution finds that the typical LAE has low stellar mass (109 M_sun), moderate star formation rate (2 M_sun/yr), a young component age of 20 Myr, and little dust (A_V<0.2). This represents our first direct knowledge of the progenitors of spiral galaxies like the Milky Way seen when the universe was only 2 Gyr in age.

"New Constraints on the Cosmic Neutrino Background"
A survey is made of the most recent constraints on Neutrino parameters from several cosmological observables. In particular, we discuss the latest cosmic bounds on the neutrino mass and their interplay with the final 0nu2beta decay results in 76-Ge claimed by part of the Heidelberg-Moscow Collaboration. Moreover, we search for the presence of cosmological neutrino background anisotropies in recent WMAP 5-year data and show that independent determinations of the age of the universe in combination with CMB data can provide the most stringent constraint on the effective number of neutrino species.
