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 , using Planck CMB data and geometrical probes from BA…

Cosmological Gravitational Waves from Ultralight Vector Dark Matter
Tomás Ferreira Chase, Tomás Ferreira Chase, Diana López Nacir +1
We compute the abundance of cosmological gravitational waves produced during the evolution of an ultralight vector (spin-1) dark matter field. A homogeneous background vector field…

Gravitational waves of quasi-circular, inspiraling black hole binaries in an ultralight vector dark-matter environment
Tomás Ferreira Chase, Diana López Nacir, Nicolás Yunes
The gravitational waves emitted by massive black hole binaries can be affected by a variety of environmental effects, which, if detected, could inform astrophysics and cosmology. W…
