New constraints on the values of the fundamental constants at a look-back time of 7.3 Gyr
Renzhi Su, Stephen J. Curran, Francoise Combes +4
The study of redshifted spectral lines can provide a measure of the fundamental constants over large look-back times. Current grand unified theories predict an evolution in these c…
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…
The critical role of dark matter halos in driving star formation
Jing Dou, Yingjie Peng, Qiusheng Gu +13
Understanding the physical mechanisms that drive star formation is crucial for advancing our knowledge of galaxy evolution. We explore the interrelationships between key galaxy pro…
Constraints on the fractional changes of the fundamental constants at a look-back time of 2.5 Myrs
Renzhi Su, Tao An, Stephen J. Curran +3
The quantum nature of gravity remains one of the greatest mysteries of modern physics, with many unified theories predicting variations in fundamental constants across space and ti…
