Multiplet Alignment: bridging large and small-scale clustering
The large-scale tidal field can be traced by the alignment of small groups, or "multiplets" of galaxies. Multiplets mostly consist of 2-4 galaxies within 1 Mpc/h of each other, and we measure their orientations relative to the galaxy-traced tidal field. Multiplet alignment has been detected in the DESI Survey out to projected separations 100 Mpc/h, demonstrating that small-scale clustering preserves an interpretable memory of large-scale structure. I will cover potential applications and a first look at multiplet alignment across cosmological simulations.
