Special RPM-Berkeley Cosmology Seminar | Sihan Yuan (Harvard University) Tackling the challenges of galaxy-dark matter connection modeling and secondary bias

January 19, 2021 @ 1:10 pm - 2:10 pm

Abstract: 
Modeling galaxy-dark matter connection is essential in deriving unbiased cosmological constraints from galaxy clustering observations. We show that a more physically motivated galaxy-dark matter incorporating secondary biases can result in more accurate predictions of galaxy clustering, and that it significantly reduces the tension in galaxy lensing. We further present progress in building a galaxy-dark matter connection framework that is rich in features and highly efficient in evaluation, enabling more robust cosmological analyses with upcoming DESI data.
