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…
