Optimal Mass Configurations for Lensing High-Redshift Galaxies (and how to find them in the SDSS!)

Seminar | September 18 | 1:10 p.m. | B1 Hearst Field Annex

Speaker/Performer: Ken Wong, Arizona

Sponsor: Department of Astronomy

We investigate whether lines of sight containing multiple cluster-scale halos are the best cosmic telescopes for lensing high-redshift (z~10) sources into detectability. For lines of sight of fixed angular size and total mass, we test how the lensing cross section and the number of faint galaxies detected at high redshift change as that mass is distributed among multiple halos, as well as which...   More >
