Disentangling the Morphology of Palomar~5: Effects of the Bar, Spiral Arms, LMC, and Halo Flattening
Zhenghao He, Long Wang, Zi-yi Zhou +2
The Palomar~5 (Pal~5) globular cluster and its tidal tails provide a sensitive probe of globular-cluster evolution in the time-dependent Milky Way potential. We study the past 3~Gy…
Kink collisions in a two-dimensional gravity model
Zhen-Tao He, Yuan Zhong
The paper numerically investigates collisions between kink and antikink solutions in a two‑dimensional φ⁴ model coupled to dilaton gravity, showing how gravity changes the scatteri…
Can Oscillatory and Persistent Nonlinearities Be Bridged in Black Hole Ringdown?
Jun-Xi Shi, Zhen-Tao He, Jiageng Jiao +4
Quadratic quasinormal modes (QQNMs) and Christodoulou memory effect are key nonlinear phenomena in gravitational wave physics. QQNMs characterize the near zone nonlinear response o…
Taxonomy of periodic orbits and gravitational waves in a non-rotating Destounis-Suvorov-Kokkotas black hole spacetime
Zhutong Hua, Zhen-Tao He, Jiageng Jiao +2
In this paper, we investigate periodic orbits of test particles around a non-rotating Destounis-Suvorov-Kokkotas black hole and the resulting gravitational waves. Firstly, we exami…
Nonlinear tails of massive scalar fields around a black hole
Caiying Shao, Zhen-Tao He, Jiageng Jiao +5
Nonlinear effects play a fundamental role in the late-time ringdown of black holes, with direct implications for gravitational-wave observations. For massive fields, these dynamics…
Constraining the Galactic bar and spiral pattern speeds with the Hyades tidal stream
Zi-yi Zhou, Long Wang, Tereza Jerabkova +1
We present a suite of direct -body simulations of the Hyades open cluster and its tidal stream in a Milky Way potential that includes a rotating bar and spiral arms. Using the h…
