Constraining Cosmological Parameters Using The Correlation Function, Michael Warrener
Constraining Cosmological Parameters Using The Correlation Function, Michael Warrener
Honors Theses
As the European Space Agency prepares to launch the space telescope Euclid in 2020, we are interested in using its observations of galaxy clustering as a new geometry-based tool to constrain the cosmological parameters Ωm and ΩΛ. In this work, we use data simulated by Magneticum (a high-resolution cosmological structure simulation) to model the correlation functions of both galaxies and clusters at several redshifts. We fit analytic models to the simulated data centered at the baryon acoustic oscillation peak to extract both the matter density parameter Ωm and the dark energy density parameter ΩΛ: We find that the correct cosmology …

In order for a robot to be effective when interacting with a person, it is important for the robot to choose the correct person. Consider an example where a robot is trying to perform a task but it isn’t capable of doing a subtask, like going up a flight of stairs. In this case, the robot would need to ask a person for help with the elevator, in a socially appropriate way. We have conducted an experiment to determine who would be the best candidate to approach in a situation like this. Should the robot choose to approach someone who …
