| 英文摘要 | Abstract With the published data of apparent axis ratios for 1109 ultra-diffuse galaxies (UDGs) located in 17 low-redshift (z ～ 0.020–0.063) galaxy clusters and 84 UDGs in two intermediate-redshift (z ～ 0.308–0.348) clusters, we take advantage of a Markov Chain Monte Carlo approach and assume a triaxial model to investigate the intrinsic morphologies of UDGs. In contrast to the conclusion of Burkert, i.e., the underlying shapes of UDGs are purely prolate (C?=?B? |
