ESO 113-IG45: galaxy and/or quasar?

Spectroscopy, UBV photometry and photography have been obtained of the extraordinary 13th magnitude object ESO 113-IG45 identified as a Seyfert galaxy by Fairall (1977); R.A.=01/sup h/ 21/sup m/.9; Decl .=-59 degrees 04' (1950). V/sub 0/=13630+or-50 km s/sup -1/; M/sub V /=-24/sup m/.0; largest...

description Spectroscopy, UBV photometry and photography have been obtained of the extraordinary 13th magnitude object ESO 113-IG45 identified as a Seyfert galaxy by Fairall (1977); R.A.=01/sup h/ 21/sup m/.9; Decl .=-59 degrees 04' (1950). V/sub 0/=13630+or-50 km s/sup -1/; M/sub V /=-24/sup m/.0; largest diameter 75 kpc or more (with H/sub 0/=55 km s /sup -1/ Mpc/sup -1/). The nucleus is stellar-like and several times more luminous than the surrounding envelope which has a well-developed lane-structure. It is the intrinsically most luminous Seyfert nuclear yet known, and may be described as a 'quasar in the center of a (spiral) galaxy'. It is probably associated with the X-ray source 2A0120-591. (14 refs).
