Energy evolution in the progenitor of galaxy shells: a semi-analytical model
Beibei Guo, Xufen Wu, HongSheng Zhao +1
The stellar shells surrounding an elliptical galaxy, as remnants of a dwarf galaxy disrupted during merging, reveal the distribution of energy and angular momentum of the progenito…
Shape asymmetries and the relation between lopsidedness and radial alignment in simulated galaxies
Jinzhi Shen, Xufen Wu, Yirui Zheng +1
Galaxies are observed to be lopsided, meaning that they are more massive and more extended along one direction than the opposite. In this work, we provide a statistical analysis of…
Collisions of young disc galaxies in the early universe
Beibei Guo, Xufen Wu, Guangwen Chen
In the local universe, disc galaxies are generally well evolved and Toomre stable. Their collisions with satellite galaxies naturally produce ring structures, which has been observ…
Cosmic Evolution of Long Gamma-Ray Burst Luminosity
Can-Min Deng, Xiang-Gao Wang, Bei-Bei Guo +5
The cosmic evolution of gamma-ray burst (GRB) luminosity is essential for revealing the GRB physics and for using GRBs as cosmological probes. We investigate the luminosity evoluti…
