Up: Line-of-sight velocity distributions of galaxies


3 Results

Emission lines were detected in 5 galaxies of the sample: UGC 4508, NGC 1889, NGC 3125, NGC 5237 and UGC 7354. Table 4 lists the detected emission lines of the respective galaxies and their properties. Analysis suggests photoionisation to be the main cause for the line emission, which is typical for H II regions.

The results for the stellar kinematics obtained for all 49 sample galaxies with absorption lines strong enough for fourier fitting are presented in the Appendix. The radial velocity and velocity dispersion profiles compare favorably with previously published measurements (Bender et al. 1994; Davies et al. 1983; Franx et al. 1989; Binney et al. 1990; Carollo & Danziger 1994a). The agreement of the kinematical profiles is for the major part within $1
\sigma$ deviation. For most of the galaxies of our sample no published h3and h4 are available for comparison.

Notes on individual objects:

IC 1729: Asymmetric radial velocity profile, central depression in the velocity dispersion profile.
NGC 1404: Disk without rotation within 0.1 $r_{\rm e}$, velocity profile constant within 1 $r_{\rm e}$, $h_3 \propto -v$: typical example of decoupled central component kinematics.
UGC 4508: cE? High-intensity emission lines, low continuum.
NGC 1889: In interaction with the disklike galaxy NGC 1888, merger. The kinematic profiles overlap, resulting in a velocity dispersion profile and line strength increase outward. H$\alpha$ and [N II] line emission were detected, possibly from the neighboring galaxy. Liu & Kennicutt (1995) state NGC 1888 to be a spiral of the type Sa or Sb with dominent old stellar population and only weak line emission.
NGC 2663: Very small rotation, unusually high velocity dispersion. This galaxy is a massive brightest cluster member and characterized by very anisotropic dynamics (Carollo & Danziger 1994b). The galaxy also features a compact central radio source (Danziger & Goss 1983; Sadler et al. 1989).
NGC 2271: Kinematically decoupled central component within 1.5'' of the galaxy's center without rotation.
NGC 3078: Slightly asymmetric kinematically decoupled central component without rotation, also supported by a central depression in the Mg2 profile (Carollo et al. 1993).
NGC 3125 = AM 1004-294: High intensity emission lines, low continuum. This is a bright, compact low-redshift galaxy in a cluster with regular outer isophotes and double knots, it is classified as an amorphous H II galaxy (Telles et al. 1997) or a blue compact dwarf (Marlowe et al. 1997).
NGC 3136: Counter-rotation disk 4'' away from the center of intensity with a diameter of 2''; significance is low.
NGC 3250: Counter-rotating disk 9'' away from the center of intensity with a diameter of 3'', h3 $\propto$ -v, indicating decoupled central component kinematics (Bender et al. 1994). The Mg2 profile of this galaxy also features a central depression (Carollo et al. 1993).
NGC 3268: This galaxy features rotation only at one side of the core probably due to the presence of dust. It also has a parsec-scale radio core (Slee et al. 1994). h3 $\propto$ v, indicating a disk component (Bender et al. 1994).
NGC 3302: Dust lane along major axis.
NGC 3557B: Possible kinematically decoupled central component supported by the asymmetric rotational velocity profile and h3 > 0, low significance because of low spatial resolution.
NGC 3636: E0 with low velocity dispersion ($\sigma$ < 160 km s-1).
NGC 3904: Rotation disk (r<6'') within the center, h3 $\propto$ -v, indicating decoupled central component kinematics.
NGC 4105, NGC 4106 = AM 1204-292: Gravitational interaction, reciprocal influence of kinematics. NGC 4105 features decoupled fast rotation within 2'' of the galaxy's center, supported by the fact that h3 resambles -v; NGC 4106 has an asymmetric rotational velocity profile and h3 > 0. The latter is classified as lenticular in the ESO-Uppsala Sky Survey with a diffuse, round arm clearly visible, possibly produced by the interaction. RC3 classifies it for this reason as SBb, however the color is more consistent with an S0 (Reduzzi & Rampazzo 1996).
NGC 4697: Large E6 galaxy with only slight rotation, it also features a dust lane of intrinsically circular shape, located in the equitorial plane. The galaxy is flattened and may be an S0, the spheroidal part of NGC 4697 may well be a large bulge (Dejonghe et al. 1996).
NGC 5237 = AM 1334-423: Nearby irregular galaxy, high-intensity emission lines, low continuum. This galaxy is believed to be a remnant of a spiral which collided with Centaurus A (NGC 5128) 5 108 yr ago, lost half its disk material, which now forms the conspicuous ring of gas and dust line in Centaurus A, and was ejected as a non-rotating shred of dusty, gas-rich disc material which appears as a blue irregular/starburst dwarf galaxy (Thomson 1992).
NGC 6861 = IC 4949: Unusually high velocity dispersion at the center, fast rotation. This is a massive S0 galaxy, possibly influenced by a bar component. This galaxy also features a compact radio source in its core (Slee et al. 1994).
UGC 7354 = A 1216+04: Only emission lines, no absorption lines detected. This is a blue compact dwarf (Papaderos et al. 1996) or a starburst galaxy (Campos-Aguilar & Moles 1991).

The ESO-Uppsala Sky Survey designates 25 galaxies as cluster members, 8 galaxies as group members, 3 galaxies as pairs (NGC 4105 with NGC 4106, NGC 5237 with a compact object) and 6 galaxies as field galaxies (IC 4797, NGC 2380, NGC 2865, NGC 2887, NGC 3302, NGC 3585). For 12 galaxies no such data was available.

Table 5 contains the most important measured or derived spectroscopic quantities of the sample galaxies. These mean parameters describe the individual galaxies sufficiently well for the investigation of correlations between different kinematic and non-kinematic properties and LOSVDs. All mean parameters refer to the galaxy properties within their effective radii.
