Alice Eve Shapley is a professor at the University of California, Los Angeles (UCLA) in the Department of Physics and Astronomy.
[1] UV spectroscopic observations of samples for z~ 3 star-forming galaxies showed uncharacteristically deep penetration into the Lyman continuum region.
Ionizing radiation escaping from individual galaxies at high red shift were detected, and the ratio of emergent flux density to Lyman continuum region was determined.
The collected data for the average emergent flux density ratio contradicted the escape fraction previously implied from past publications.
Emission lines and absorption features allowed the group to determine the metallicity of CASSOWARY 20 with a small level of uncertainty.
[9] For this publication Shapley looks at a census of the methods used to find distant galaxies as well as the empirical constraints on their multi-wavelength luminosities and colors.
