Section 4.2.3 Interacting Galaxy: NGC 4676:
NGC 4676 is commonly known as 'The Mice' for obvious reasons. It consists of two galaxies, NGC 4676a (the northernmost galaxy) and NGC 4676b. It is 87 Mpc distant.
HST NICMOS J,H and K imaging is presented in Rossa et al. (2007).
The VLA HI tails are extensive, as is the HII emission, showing evidence for widespread star formation (Hibbard and van Gorkom 1996) induced by the encounter.
1The encounter is called prograde when the orbital spin angular momentum of the companion galaxy is aligned with the spin angular momentum of the target galaxy.
