EXTENDED IONIZED-GAS IN ELLIPTIC GALAXIES .1. MULTICOMPONENTS IN NGC-1052 AND NGC-7332

A number of elliptical galaxies possess an extended gaseous disk usual ly detected in [OIII] 5007 Angstrom, H alpha or [NII] 6583 Angstrom em ission lines. 3-D scanning Perot-Fabry observations of two of these ob jects, NGC 1052 and NGC 7332, show multiple profiles of the ionized fa int and extended gas. We separate clearly two extended gaseous compone nts in both galaxies where gas kinematics is largely decoupled from st ellar one. Several gas systems, kinematically decoupled and possibly l ocated in different basic planes of the ellipsoids, could be related t o different external origins. We used gas kinematics to constraint the triaxial shape of these galaxies. Both present a typical gaseous disk which may lie in an allowed preferred plane of the ellipsoid. But the re is no clear coherence between dynamical parameters derived separate ly from the gaseous disks. Different hypothesis, in which one componen t is not definitively stable, are presented. They suppose that success ive mergers occurred within a relatively small time scale.
