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…
Ultralight vector dark matter, anisotropies and cosmological adiabatic modes
Tomás Ferreira Chase, Diana López Nacir
In this work we study the early time behavior and the background evolution of ultralight vector dark matter. We present a model for vector dark matter in an anisotropic Bianchi typ…
