Where Galaxies Point: First Measurement of the Large-Scale Axial Intrinsic Alignment
Pedro da Silveira Ferreira, Rafael Oliveira Ramos, Paula S. Ferreira +5
We report evidence for large-scale axial intrinsic alignment (LAIA): a coherent axis shared by galaxies and cosmic-web filaments. Applying an orientation-field estimator to Dark En…

Probing cosmology with bright sirens from the CosmoDC2_BCO LSST synthetic catalog
Ranier Menote, Valerio Marra
Bright sirens, i.e. gravitational-wave detections of compact binary mergers with electromagnetic counterparts, provide a self-calibrated distance-redshift relation and are therefor…

Gravitational-wave and electromagnetic detections in the context of the CosmoDC2 LSST synthetic catalog
Ranier Menote, Valerio Marra, Riccardo Sturani +3
We release CosmoDC2_BCO, a synthetic catalog of gravitational-wave events and electromagnetic counterparts associated with galaxies from CosmoDC2. The catalog provides intrinsic an…
