"Galaxy Weak Lensing with DESI"
Insights into galaxy weak lensing with DESI and its synergies for advancing cosmology.

Agne Semenaite (Swinburne University) presents recent work from the DESI galaxy weak lensing group. The talk will cover strategies for mitigating weak lensing systematics, advances in understanding galaxy intrinsic alignments, tests of modified gravity, and the “lensing is low” phenomenon. It will also highlight upcoming joint analyses combining galaxy clustering and shear, demonstrating how DESI spectroscopy complements other cosmological surveys.
