Age and Mass Signatures in the Multiband Second-order Image Structure of Young Star Clusters in M31
Yuan Liang, Chao-Wei Tsai, Jingwen Wu
The ages and masses of star clusters may leave systematic signatures in the second-order spatial structure of semi-resolved photometric images. To test this hypothesis, we analyze…
A Deep Study of the Spiral Galaxy W2246f
Evelyn J. Johnston, Sorya Lambert, Aparna Nair +10
In this era of large surveys and statistical studies of galaxies, the beauty in the details of individual galaxies is often lost. We present a deep study of the spiral galaxy W2246…
Compact, AGN-hosting Dwarf Galaxies with "Little Red Dots"-like SEDs in the Local Universe
Lulu Bao, Chao-Wei Tsai, Jingwen Wu +1
Local active galactic nuclei (AGNs) in dwarf galaxies are often considered as analogs for the earliest supermassive black holes, although their connections require more comprehensi…
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…
Implications for galaxy property estimation revealed by CO luminosity-FWHM relations in local star-forming galaxies
Yi-Han Wu, Jun-Feng Wang, Xiao-Hu Li +6
This study explores a relationship between the CO luminosity-full width at half-maximum linewidth linear relation (i.e. the CO LFR) and mean galaxy property of the local star-formi…
