Pixelized galaxy cluster strong lens modeling improves precision of Hubble constant measurement
For the first time, an international research team led by the Shanghai Astronomical Observatory (SHAO) of the Chinese Academy of Sciences has demonstrated that applying pixelized strong-lensing modeling on a galaxy cluster scale can significantly improve the precision of the inferred Hubble constant (H0)—a key parameter that describes the expansion rate of the universe.
