Hessian-based photometric substructure as an evolutionary tracer of OB cluster candidates in M31
Yuan Liang, Chao-Wei Tsai, Jingwen Wu
Using \textit{Hubble Space Telescope} images from the PHAT and PHAST surveys, we construct an updated catalogue of 747 OB cluster (OBC) candidates. We introduce a dimensionless str…

A comprehensive catalogue of OB cluster candidates in M31 and their association with giant molecular clouds
Yuan Liang, Guang-Wei Li, Chao-Wei Tsai +1
We present a new catalogue of 578 OB cluster (OBC) candidates in the Andromeda galaxy (M31), identified using a MeanShift-based algorithm on HST's F275W-band imaging from the PHAT…
