I tried to think of a way to send stellar population of a disk galaxy flying in two opposite direction…
And failed.
The gas of a disk galaxy is viscous.
The dust may be dragged by the gas flow and by radiation.
An active BH might blew them both away.
But not the stellar population and, for that matter, the dark matter halo of that disk galaxy
Must be a rogue AGN.
This NIR-bright (JWST-spiky) object seem to have two pairs of jets and a curved dusty trail from the disk galaxy at the bottom.
A rogue AGN might belong to the dwarf galaxy at the left, seeing it's curved stellar trail is almost parallel.
A dwarf galaxy can loose its central black hole when piercing a disk galaxy if both central BHs get really close for a moment, can it not?
The dwarf and the rogue AGN's trails we currently see are missing the core of the disk galaxy, so this is not their first orbit after the separation.
