Analysis of the Potential Hoag-type Galaxy WISEA J234255.19-354810.2

Scholarly Text or Essay


Ring galaxies are among the most perplexing phenomena we observe in space. Their formation has remained a topic of debate, especially since 1950 when Arthur Hoag discovered Hoag’s Object. Hoag-like objects are exceedingly rare and the ring galaxy WISEA J234255.19-354810.2 has the potential to be the 16th Hoag-type galaxy discovered. I performed two types of data analysis to obtain information about the galactic light profiles. From this analysis, I discovered a very faint bar structure within the core of the ring galaxy, which indicates that WISEA J234255.19-354810.2 is not a Hoag-type galaxy.
