Static spherical vacuum solutions in the bumblebee gravity model

Kavli Affiliate: Lijing Shao | First 5 Authors: Rui Xu, Dicong Liang, Lijing Shao, , | Summary: The bumblebee gravity model is a vector-tensor theory of gravitation where the vector field nonminimally couples to the Ricci tensor. By investigating the vacuum field equations with spherical symmetry, we find two families of black-hole (BH) solutions in […]

The EDGE-CALIFA survey: the role of spiral arms and bars in driving central molecular gas concentrations

Kavli Affiliate: Luis C. Ho | First 5 Authors: Si-Yue Yu, Veselina Kalinova, Dario Colombo, Alberto D. Bolatto, Tony Wong | Summary: Shocks and torques produced by non-axisymmetric structures such as spiral arms and bars may transport gas to galaxy central regions. We test this hypothesis by studying the dependence of concentration of CO luminosity […]
