Description
We present the first confirmation of anisotropic halo bias induced by vector dark matter/energy and anisotropic inflation. Vector dark matter/energy and anisotropic inflation models distort cosmological matter distributions. Anisotropy of matter distributions can affect halo distributions. Using cosmological N-body simulations, we show that halo bias becomes anisotropic in the presence of vector dark matter/energy and/or anisotropic inflation.
