We have discovered strong gravitational lensing features in the core of the nearby cluster Abell 3827 by analyzing Gemini South GMOS images .
The most prominent strong lensing feature is a highly-magnified , ring-shaped configuration of four images around the central cD galaxy .
GMOS spectroscopic analysis puts this source at z \sim 0.2 .
Located \sim 20″ away from the central galaxy is a secondary tangential arc feature which has been identified as a background galaxy with z \sim 0.4 .
We have modeled the gravitational potential of the cluster core , taking into account the mass from the cluster , the brightest cluster galaxy ( BCG ) and other galaxies .
We derive a total mass of ( 2.7 \pm 0.4 ) \times 10 ^ { 13 } M _ { \odot } within 37 h ^ { -1 } kpc .
This mass is an order of magnitude larger than that derived from X-ray observations .
The total mass derived from lensing data suggests that the BCG in this cluster is perhaps the most massive galaxy in the nearby universe .
