I haven’t read the full paper yet, but I believe these are cousins of the “little red dots”, they are point-like objects which are very similar to galaxies but don’t seem to have the full characteristics of a galaxy (being a large collection of many stars in orbit around its collective center of mass). There doesn’t seem to be enough data to say exactly what’s going on here, just raise more questions.

A platypus (galaxy, star, etc.) is a combination of disparate characteristics that are specifically different and combined in a form that makes no sense, but exists, much like a platypus is a compendium of appendages and traits.
The findings about these galaxies are more related to their respective lack of spectral signal across the usual range while still being found in a specific spectral frequency. Also small but likely young and denser (compact) than projections would show.
Likely dense bh galaxies with early h gas components (or h he) where the compactness is the bh spinning slowly, not enough to eat in the local galaxy, has consumed to the point of self sustaining static state, likely a form of small seed galaxy that merges in later evolution to create supermassive bh etc. the denseness of the objects compared to their relative light (whole) vs spectral freq amplitude and narrowness. Self binding energy increases with time and increases area, likely leading to cascade dynamics where small galaxies and small galaxies pull in larger galaxies when they merge. Our timelines can only accommodate linear (2body dynamics), these turn into n body problems, cascading * area expansion * energy flux.

We bad at naming things, aren’t we? 😅
For anyone wondering what a “platypus galaxy” is, you should know that I too do not know.
