CDN-271: The Group Test

Testing the GCFT dark-matter reduction factor at galaxy-group scale (M~10^12-10^14 M_sun) reveals R~0.70: the MOND interpolation function nu(x) is active (3-4x boost at x~0.1) but insufficient in baryon-poor systems (f_bar~10%). This confirms two distinct coupling channels: nu(x) at g<=a0 and the cluster kappa-proxy at g>>a0.

Abstract

Testing the GCFT dark-matter reduction factor at galaxy-group scale (M~10^12-10^14 M_sun) reveals R~0.70: the MOND interpolation function nu(x) is active (3-4x boost at x~0.1) but insufficient in baryon-poor systems (f_bar~10%). This confirms two distinct coupling channels: nu(x) at g<=a0 and the cluster kappa-proxy at g>>a0.
