Super Nova IA
In May 2019, Dark Energy Survey team published their first cosmology results using type IA supernova. The super Nova data was from DES-SN3YR. The Dark Energy Survey team found Ωm = 0.331 ± 0.038 with a flat ΛCDM model and Ωm = 0.321 ± 0.018, w = −0.978 ± 0.059 with a flat wCDM model. Analyzing the same data, they also found a new current Hubble constant, $$H_0= 67.1 \pm1.3 kms^{-1}Mpc^{-1}$$.

dwarf GALAXY results

Later on, Dark Energy Survey team found more dwarf galaxies. With more Dwarf Galaxy results, the team was able to take a deep look about more properties of the detected Dwarf Galaxy such as the chemical abundance, the structure of stellar population and Stellar Kinematics and Metallicities. In Feb 2019, the team also discovered six more star clusters in the Fornax Dwarf Spheroidal Galaxy and a tidally Disrupted Ultra-Faint Dwarf Galaxy ,
