UGC 4599: a photometric study of the nearest Hoag-type ring galaxy

Abstract: We present a photometric study of UGC 4599, a low‐luminosity galaxy superficially resembling Hoag's Object in that on sky survey images it appears to be a complete ring surrounding a roundish core. The nature of the outer ring of Hoag‐type galaxies is still debated and may be related either to slow secular evolution or to environmental processes, such as galaxy–galaxy interactions. As the nearest of its kind, UGC 4599 is a perfect target for a detailed study of the peculiar structure of this type of objects. S… Show more

“…This possible combination of rare circumstances can be dismissed since our data strongly indicate that the system has nearly reached equilibrium. Since such a relaxed structure is also seen in the Hoag‐type galaxy UGC 4599, we conclude that the collisional ring scenario is not responsible for forming genuine Hoag‐type galaxies (Finkelman & Brosch 2011).…”

“…In some cases, radio observations also reveal signs of interactions with neighbouring galaxies, such as H i bridges or tails (e.g. Finkelman & Brosch 2011). Exploring the H i environment at high sensitivity is therefore essential to complement our optical study.…”

“…Whitmore et al (1990) considered this galaxy as possibly related to a PRG. The most similar galaxies in our catalogue are SPRC‐250 (see its photometric study in Finkelman & Brosch 2011), SPRC‐261 and SPRC‐265.…”
