A spectroscopic follow up of Ultra-Compact Dwarf ( UCD ) candidates in the fossil group NGC 1132 is undertaken with the Gemini Multi Object Spectrograph ( GMOS ) .
These new Gemini spectra prove the presence of six UCDs in the fossil group NGC 1132 at a distance of D \sim 100 Mpc and a recessional velocity of v _ { r } = 6935 \pm 11 km/s .
The brightest and largest member of the UCD population is an M32 analog with a size of 77.1 pc and a magnitude of M _ { V } =-14.8 mag with the characteristics in between those of the brightest UCDs and compact elliptical galaxies .
The ensemble of UCDs have an average radial velocity of < ~ { } v _ { r } ~ { } > = 6966 \pm 208 km/s and a velocity dispersion of \sigma _ { v } = 169 \pm 18 km/s similar to the one of poor galaxy groups .
This work shows that UCDs can be used as test particles to determine the dynamical properties of galaxy groups .
The presence of UCDs in the fossil group environment is confirmed and thus the fact that UCDs can form across diverse evolutionary conditions .
