Stephen Portillo, University of Washington, "Counting Stars: Developing Probabilistic Cataloging for Crowded Fields"
KICP seminar: Dec 14 @ 12 PM, ERC 401
The depth of next generation surveys poses a great data analysis challenge: these surveys will suffer from crowding, making their images difficult to deblend and catalog. Sources in crowded fields are extremely covariant with their neighbors and blending makes even the number of sources ambiguous.
