echo-IA (Enabling Cosmology with Homogenized Observations of Intrinsic Alignments)
is a collaboration of researchers working on intrinsic alignments (IA) across modeling, observations, and simulations.
We serve as a central hub that connects efforts, datasets, and tools from many teams, making IA research more cohesive, comparable, and reproducible.
Through shared standards and open infrastructure, we aim to accelerate progress toward a unified understanding of intrinsic alignments across surveys and methods.
