Spin-1 Ultralight Dark Matter under Cosmological Scrutiny: Mass Constraints from CMB and Distance Probes

Guadalupe Ahumada Acuña, Tomas Ferreira Chase, Diana López Nacir +1

We present cosmological constraints on spin-1 ultralight dark matter, described by a vector field (VFDM) with mass $m_{\mathrm{A}}$, using Planck CMB data and geometrical probes from BA…
