A multiple galaxy collision in compact groups

A multiple galaxy collision in compact groups

It is shown that the dynamical paradox of the HCG 90, which is treated as an old, and at the same time, as a young system (White et al), may be solved assuming that it is a rotating system in which multiple collisions have occurred during Hubble time. In the frames of the same scenario a multiple co...

Zusammenfassung:It is shown that the dynamical paradox of the HCG 90, which is treated as an old, and at the same time, as a young system (White et al), may be solved assuming that it is a rotating system in which multiple collisions have occurred during Hubble time. In the frames of the same scenario a multiple collisions in SQ (HCG 92) are naturally explained. (© 2003 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
