Survival or Destruction: Effects of Spheroidal Satellite Collisions on Bars in Milky Way-Like Galaxies
Yufan Zhou, Zhiyuan Li, Óscar Jiménez-Arranz +1
Although stellar bars are prevalent in local galaxies, unbarred galaxies constitute a significant fraction, particularly at high redshifts. While some galaxies are unbarred by natu…
N-body simulations of galaxy bars generated by satellite collisions: effects of the impact geometry
Yufan Fane Zhou, Zhiyuan Li, Hui Li
Bars, a common and important structure in disk galaxies, can be induced by galaxy interactions. Although there have been some studies on bar formation in flybys or collisions, the…
Ring or no ring -- Revisiting the Multiphase Nuclear Environment in M31
Zongnan Li, Zhao Su, Sumin Wang +9
Nuclear rings, prevalent in barred galaxies, are essential to understanding gas transport toward galactic nuclei. However, the peculiar nuclear ring in our neighboring galaxy M31 r…
Prediction for close approaches with terrestrial planets of asteroids from the main belt
Yufan Fane Zhou, Zhiyuan Li, Hailiang Li +1
Potentially Hazardous Asteroids (PHAs), a special subset of Near-Earth Objects, are both dangerous and scientifically valuable. PHAs that truly undergo close approaches with the Ea…
MARTIANS (MARs2020, TIANwen and So on) would see more potentially hazardous asteroids than Earthlings
Yufan Fane Zhou, Hailiang Li, Zhiyuan Li +1
Potentially Hazardous Asteroids (PHAs) are a special subset of Near-Earth Objects (NEOs) that can come close to the Earth and are large enough to cause significant damage in the ev…
