How do uncertainties in galaxy formation physics impact field-level galaxy bias?

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Mahlet Shiferaw, Nickolas Kokron, Risa H. Wechsler, , | Summary: Our ability to extract cosmological information from galaxy surveys is limited by uncertainties in the galaxy-dark matter halo relationship for a given galaxy population, which are governed by the intricacies of galaxy formation. To quantify these […]
