We present a study of outflow and feedback in the well-known Seyfert 2 galaxyMarkarian 573 using high angular resolution long-slit spectrophotometryobtained with the Hubble Space Telescope Imaging Spectrograph (STIS). Throughanalysis of the kinematics and ionization state of a biconical outflow regionemanating from the nucleus, we find that the outflow does not significantlyaccelerate the surrounding host-galaxy interstellar gas and is too weak to be astrong ionization mechanism in the extended emission regions. Instead, theexcitation of the extended regions is consistent with photoionization by theactive nucleus. From energetics arguments we show that the nuclear outflow isslow and heavy and has a mechanical luminosity that is only ~1% of theestimated bolometric luminosity of the system. The energy in the outflow isable to mildly shape the gas in the extended regions but appears to beinsufficient to unbind it, or even to plausibly disrupt star formation. Theseresults are at odds with the picture of strong AGN feedback that has beeninvoked to explain certain aspects of galaxy evolution.
