The Role of Nuclear Starbursts in Luminous Infrared Seyfert 2 Galaxies

We present HST (WFPC2 and FOC) images and UV GHRS spectraplus ground-based optical spectra of four Luminous Infrared Galaxies (LIRGs) that have Seyfert 2nuclei (Mrk 477, NGC 7130, NGC 5135 and IC 3639). The data provide direct evidence of the existence of a central nuclearstarburst that dominates th...

description We present HST (WFPC2 and FOC) images and UV GHRS spectraplus ground-based optical spectra of four Luminous Infrared Galaxies (LIRGs) that have Seyfert 2nuclei (Mrk 477, NGC 7130, NGC 5135 and IC 3639). The data provide direct evidence of the existence of a central nuclearstarburst that dominates the UV and optical light and are dusty and compact. The bolometricluminosity ( 10^sup 10^ L) of these starbursts is similar to the estimated bolometric luminosities of their obscured Seyfert 1 nuclei, and thus they contributein the same amount to the overall energetics of these galaxies. An extended work based on ground-based optical spectra of the 20 brightest nuclei known indicate that at least 40%of the Seyfert 2 galaxies harbor a nuclear starburst. The eight Seyfert 2 nuclei thatharbor a starburst are strong IR emitters. This suggests that nuclear starbursts can make a significant contribution or even dominate the UV and optical light of LIRGs.[PUBLICATION ABSTRACT]
