When Galaxies Refuel: Evolution of the Perturbed Spiral Galaxy NGC1385
Xiaoyu Kang, Eva Sextl, Rolf-Peter Kudritzki +5
The spiral galaxy NGC 1385 is characterized by a vigorous and protracted history of star formation, particularly in its central regions, leading to a current star formation rate th…
Environmental dependence of Type Ia supernova standardization on the local luminosity-weighted age
Yuhui Zhang, Xiangcun Meng, Jingxiao Luo +3
Context. The dependence of Type Ia supernova (SNe Ia) standardized luminosity on host galaxy properties constitutes a significant systematic error in cosmology. However, the widely…
Radial Profiles of Binary Fraction in Elliptical Galaxies
Xiejin Li, Fenghui Zhang, Yinghe Zhao +4
The radial profile of binary fraction may vary with environment and is of significant importance for studying the formation mechanisms of binary stars and their dynamical evolution…
BayeSED-GALAXIES II. Bayesian full spectrum analysis of galaxies and application in the CSST wide-field slitless spectroscopy survey
Yunkun Han, Xian Zhong Zheng, Xiaohu Yang +21
The China Space Station Telescope (CSST) will conduct wide-field multiband photometric imaging and slitless spectroscopic surveys, advancing cosmology and galaxy evolution studies.…
Evolution and star formation history of NGC300 from a chemical evolution model with radial gas inflows
Xiaoyu Kang, Rolf-Peter Kudritzki, Xiaobo Gong +1
In the build-up of galactic discs gas infall is an important ingredient and it produces radial gas inflows as a physical consequence of angular momentum conservation, since the inf…
A post-common-envelope binary with double-peaked Balmer emission lines from TMTS
Qichun Liu, Xiaofeng Wang, Jie Lin +20
The dynamical method provides an efficient way to discover post-common-envelope binaries (PCEB) with faint white dwarfs (WDs), thanks to the development of time-domain survey proje…
