Abstract
We summarize common notations and concepts in the field of Intrinsic Alignments (IA). IA refers to physical correlations involving galaxy shapes, galaxy spins, and the underlying cosmic web. Its characterization is an important aspect of modern cosmology, particularly in weak lensing analyses. This resource is both a reference for those already familiar with IA and designed to introduce someone to the field by drawing from various studies and presenting a collection of IA formalisms, estimators, modeling approaches, alternative notations, and useful references.

- The cosmic web leaves a mark on visible matter through subtle correlations involving galaxy shapes. How do we quantify these "Intrinsic Alignments"?
For the long answer, see “The IA Guide”, now on arX [bsky, 20 points, 1 comments]
