An emission line region associated with 3C 273.
Abstract
We have observed an extended emission line region about 4" to the South-East of 3C 273 in the light of the lines [OII]λ372.8nm and [OIII]λ500.7nm, with an overall linear dimension of ~20x10kpc and a brightness of ~10^-18^W/m^2^ in either line. HST images show the region to be split up into several knots. The line intensity ratios and colors are consistent with UV excitation from the QSO, but also with shock excitation due to a possible collision of the cloud with the gas of the host galaxy of 3C 273 at high velocity.
