On primordial universe in anti-de Sitter landscape
Pu-Xin Lin, Hai-Long Huang, Jun Zhang +1
How the spacetime evolved non-perturbatively in a landscape with multiple anti-de Sitter (AdS) vacua, which is theoretically well-motivated, has always been a matter of concern. As…
Spectral stability of near-extremal spacetimes
Huan Yang, Jun Zhang
It has been suggested that the spectrum of quasinormal modes of rotating black holes is unstable against additional potential terms in the perturbation equation, as the operator as…
Instability of spherically-symmetric black holes in Quadratic Gravity
Aaron Held, Jun Zhang
We investigate the linear stability of the two known branches of spherically-symmetric black holes in Quadratic Gravity. We extend previous work on the long-wavelength (Gregory-Laf…
Dark Matter In Extreme Astrophysical Environments
Masha Baryakhtar, Regina Caputo, Djuna Croon +37
Exploring dark matter via observations of extreme astrophysical environments -- defined here as heavy compact objects such as white dwarfs, neutron stars, and black holes, as well…
Schwarzschild quasi-normal modes of non-minimally coupled vector fields
Sebastian Garcia-Saenz, Aaron Held, Jun Zhang
We study perturbations of massive and massless vector fields on a Schwarzschild black-hole background, including a non-minimal coupling between the vector field and the curvature.…
