HCG 003 – Group with one background member

HCG 003 has three galaxies at redshift ~7500 km/s and one galaxy at redshift ~11500 km/s. There doesn’t seem to be indicators suggesting that the higher redshift galaxy would not be a background galaxy accidentally positioned within group’s area.

Objects (NED search within 10 arcmin):
– PGC 002064, 7860 km/s
– PGC 002059, 11545 km/s
– MCG -01-02-032, 7302 km/s
– PGC 002043, 7804 km/s

Outside of the field shown in the figure above there are some additional interesting objects:
– SDSS J003440.06-073637.1, z = 0.507
– SDSS J003419.48-073149.5, z = 0.526
– LEDA 138198, 8017 km/s
– MCG -01-02-035, 7882 km/s
– Further out there are some additional high redshift objects (z = 0.14 … 2.27)
