The Fornax dwarf spheroidal galaxy hosts six globular clusters that present a long standing dynamical puzzle: models predict they should have sunk toward the galaxy’s center, yet they remain at large radii.
With LSST DP1, we aim to search for faint outer structure indicating ongoing interaction with the galaxies gravitational potential.
In this poster, we present a gri photometric catalogue for Fornax GC 3, along with its colour magnitude diagram, stellar density map, and radial density profile.
