A V, (B-V) C-M diagram for the distant globular cluster NGC 5824 is obtained from CCD observations of 285 stars reaching V = 20.5. Assuming a reddening of E(B-V) = 0.13, the color of the giant branch at the level of the ...

Numerical experiments have been performed to study the transfer of angular momentum to an initially non-rotating spherical galaxy as it undergoes a collision with a point mass perturber moving in a relative orbit of constant ...
