Extended emission-line gas in the high luminosity, low redshift QSO E1821+643.
FRIED J.W.
Abstract (from CDS):
The luminous RQQ E1821+643 has many properties of radio-loud quasars but is classified as radio-quiet. We have obtained an off-nuclear spectrum which shows extended emission line gas (EELG) associated with the QSO. The luminosity in extended [OIII] is about 2 orders of magnitude higher than what is typically found for radio-quiet QSOs, and is in the range of luminosities typical of radio-loud quasars. The luminosity of the EELG is another property that E1821+643 has in common with RLQs. There is no evidence for a cooling flow, suggesting that the extra-nuclear gas results from tidal interaction.
