YOUNG's breaking news

[May 11, 2023] Dr. Kyle Finner, a YOUNG alumni, was awarded JWST time to observe the massive galaxy cluster XLSSC122 at a redshift of 2.
[Apr 26, 2023] The paper entitled "Model-Independent Mass Reconstruction of the Hubble Frontier Field Clusters with MARS Based on Self-Consistent Strong Lensing Data" was accepted to ApJ (Cha & Jee 2023).
[Jan 5, 2023] The paper entitled "intracluster light is already abundant at redshift beyond the unity" is published in Nature (Joo & Jee 2023).
