Hα Kinematics of the Isolated Interacting Galaxy Pair KPG 486 (NGC 6090)

Rosado, M.; Sánchez-Cruces, M.; Sardaneta, M. M.

In optical images, the barely studied isolated interacting galaxy pair KPG 486 (NGC 6090) displays similar features to the Antennae (NGC 4038/39) galaxy pair. To compare the distribution of ionized hydrogen gas, morphology and kinematic and dynamic behaviour of both galaxy pairs, we present observations in the Hα emission line of NGC 6090 acquired…
