Scientific paper

WFPC2 snapshot imaging shows a dust lane connecting the members of the strongly interacting galaxy pair NGC 1409/10, as well as polar dust structure in NGC 1409. This is an excellent case for direct mass transfer during a tidal encounter, and a unique chance to estimate the total mass and deposition rate during such transfer. I propose two-color STIS imagery of this system, which will allow a three-dimensional reconstruction of the dust geometry. The results will show whether these dust structures in fact connect and wrap around the recipient galaxy, making this a genuine instance of mass dumping, for which a mass-flow rate could be estimated from broad dynamical considerations. Two passbands are needed to break the depth/extinction degeneracy that remains from single-passband data.
