Hubble Space Telescope detection of Spiral Structure in Two Coma Cluster Dwarf Galaxies

Graham, John A; Jerjen, Helmut; Guzman, Rafael

Description

We report the discovery of spiral-like structure in Hubble Space Telescope images of two dwarf galaxies (GMP 3292 and GMP 3629) belonging to the Coma Cluster. GMP 3629 is the faintest such galaxy detected in a cluster environment, and it is the first such galaxy observed in the dense Coma Cluster. The large bulge and the faintness of the broad spiral-like pattern in GMP 3629 suggest that its disk may have been largely depleted. We may therefore have found an example of the "missing link" in...[Show more]
