José Manuel Zorrilla Matilla
I am a sixth year graduate student at the Columbia University department of Astronomy, working with Zoltán Haiman. My research focuses on using gravitational lensing to constrain cosmology. In particular, I am interested in extracting non-Gaussian information from weak lensing data through alternative observables to the power spectrum and machine learning algorithms. My work relies on ray-tracing cosmological simulations, some of which can be accessed at the Columbia Lensing group's site.
I am also interested in characterizing the distribution of baryons in the universe, and their impact on lensing statistics, combining theory and observations of the Sunyaev Zeld'ovich effect.
