Physics/Astronomy C290C Cosmology Seminar
The Physics/Astronomy C290C series consists of the LBNL-Physics-Astronomy Cosmology seminars held Tuesdays 1:10-2:00 pm in room 544 Campbell Hall (also videoconferenced to LBL 50A-5131). Feel free bring your lunch.
Please contact Joanne Cohn to add to this list or to suggest speakers.

"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.
