Model-independent parameters from DESI DR1 LRG2 with an explicitly varying power-spectrum shape
The study developed a method using an emulator built on a hybrid model to simultaneously constrain cosmological shape parameters and model-independent distance/growth parameters from DESI DR1 LRG2 data. The analysis yielded consistent measurements for Alcock-Paczynski parameters, the growth rate, and the Hubble constant ($h=0.724 ext{pm}$), showing mutual consistency when projected onto flat $\Lambda$CDM.
