NGC 6251 at multiple scales and wavelengths
P. N. Werner, D. M. Worrall, M. Birkinshaw
We have studied the FR I radio galaxy NGC 6251 and its environment at several wavelengths and scale lengths. On the large scale, we have probed the gravity field by measuring the v…

A spectroscopic study of NGC 6251 and its companion galaxies
P. N. Werner, D. M. Worrall, M. Birkinshaw
Measurements of the velocities of galaxies thought to be associated with the giant radio galaxy NGC 6251 confirm the presence of a poor cluster with a systemic redshift of z= 0.024…

Redshift and velocity dispersion of the cluster of galaxies around NGC 326
P. N. Werner, D. M. Worrall, M. Birkinshaw
Redshifts of several galaxies thought to be associated with NGC 326 are determined. The results confirm the presence of a cluster and find a mean redshift of z = 0.0477 +/- 0.0007…
