We present three separate void catalogs created using a volume-limited sample of the DESI Year 1 Bright Galaxy Survey. We use the algorithms VoidFinder and V2 to construct void catalogs out to a redshift of z=0.24. We obtain 1,461 interior voids with VoidFinder, 420 with V2 using REVOLVER pruning, and 295 with V2 using VIDE pruning. Comparing our catalog with an overlapping SDSS void catalog, we find generally consistent void properties but significant differences in the void volume overlap, which we attribute to differences in the galaxy selection and survey masks. These catalogs are suitable for studying the variation in galaxy properties with cosmic environment and for cosmological studies.

  1. Why Cosmic Voids Matter: Pristine Evolution

    astro-ph.CO 2025-09 conditional novelty 7.0

    Cosmic voids traced by halos become stable at late times, and the matter around them evolves linearly, supporting their use as clean dark-energy probes.

  2. Unveiling $f(R)$ Gravity with Void-Galaxy Cross-Correlation Multipoles

    astro-ph.CO 2026-05 unverdicted novelty 6.0

    Void-galaxy cross-correlation multipoles exhibit amplified size-dependent deviations from LCDM in f(R) gravity due to the scalaron fifth force and nonlinear shell dynamics, providing a new probe for modified gravity.

  3. Unveiling $f(R)$ Gravity with Void-Galaxy Cross-Correlation Multipoles

    astro-ph.CO 2026-05 unverdicted novelty 6.0

    Semi-analytical calculation of void-galaxy cross-correlation multipoles in Hu-Sawicki f(R) gravity reveals size-dependent deviations from LambdaCDM up to 29.7 percent for small voids, amplified by nonlinear evolution ...
