| Abstract: | We analyze empirical relationships between optical, near infrared, and HI characteristics of isolated galaxies from the 2MIG
Catalog covering the entire sky. Data on morphological types, K
S
−, and B-magnitudes, linear diameters, HI masses, and rotational velocities are examined. The regression parameters, dispersions,
and correlation coefficients are calculated for pairs of these characteristics. The resulting relationships can be used to
test the hierarchical theory of galaxy formation through numerous mergers of cold dark matter. |
