3. Individual comments on galaxies


KAZ 001: Emission lines of [SII], [OIII],[OII], tex2html_wrap_inline1414 and tex2html_wrap_inline1416. The Balmer lines from tex2html_wrap_inline1418 to tex2html_wrap_inline1420 as well as Ca II tex2html_wrap_inline1422 3934 in absorption. More details on optical spectra are given by Kazarian & Khachikian (1974), and
Kazarian et al. (1982). It should be noted that the values of the maximum rotational velocity (interpreted as the mass within a certain radius) estimated from both optical and radio measurements can not be compared because they do not refer to the same scale within the disc (only the central parts, within 2 kpc, contribute to the optical measurement, as the globality of the HI disc enters the HI profile width). The 21-cm line profile is very well defined.
KAZ 003: Starburst galaxy with spectrum very similar to that of KAZ 1 (Kazarian & Khachikian 1974). More details in Kazarian et al.\ (1982). The 21-cm line profile is very well defined with a double-peaked shape typical of spirals.
KAZ 004: Starburst galaxy with emission lines of [SII] tex2html_wrap_inline1424 6731/17 and [NII] tex2html_wrap_inline1424 6584/48, tex2html_wrap_inline1414, [OIII] tex2html_wrap_inline1424 5007/4959, tex2html_wrap_inline1416 and tex2html_wrap_inline1418 observed in the spectra. The lines of Balmer series from tex2html_wrap_inline1436 to tex2html_wrap_inline1420 are observed in absorption. This galaxy has been observed 121 cycles but only 73 of them resulted usable due to many interferences quite usual in this low frequency range. Too noisy spectrum.
KAZ 006: Emission lines [SII] tex2html_wrap_inline1424 6731/17, [NII] tex2html_wrap_inline1424 6584/48 and tex2html_wrap_inline1414 are observed in the spectrum. The redshift given by Kazarian (1979a) is z=0.0267 (tex2html_wrap_inline1448) and differs from that presented in Table 1. Only 15 cycles were available, there is a hint of HI detection near tex2html_wrap_inline1450 but the signal is too faint compared with the noise.
KAZ 016: On the plates taken in prime focus of 2.6 m telescope of Byurakan Observatory (scale tex2html_wrap_inline1452) two circular condensations separated by 8'' are seen. Morphological type given in LEDA is Sc, but it is classified as irregular by Kazarian (1979a). Pair galaxy: HI confusion with companion UGC 41, which is a Sc galaxy with same magnitude, same inclination, and approximately same velocity (tex2html_wrap_inline1456, [18]). Steep-sided HI profile typical of a spiral galaxy, but the two profiles are most probably superimposed (this could explain the peculiar shape of the high velocity peak).
KAZ 018: According to Kazarian this is an irregular galaxy with bright central region measuring tex2html_wrap_inline1458 which could be taken for a bar (morphological type in LEDA is SBbc). UBV-photometry carried out by Tamazian (1983) shows that the nucleus is rather blue (U-B=-0.11, B-V=+0.43). Integral color U-B=0.23, B-V=+0.69. Assymetrical HI profile.
KAZ 019: Spiral with bright nucleus of about 4''. According to Tamazian (1983), the nucleus is very blue (U-B=-0.31, B-V=+0.36), integral color of galaxy U-B=-0.02, B-V=+0.49. Well defined double-peaked profile.
KAZ 023: The morphological type given in original list is elliptical whereas in LEDA it is described as Sc. Integral color U-B=+0.25, B-V=+0.68 but the nucleus is much bluer - U-B=-0.14, B-V=+0.48 (Tamazian 1983). Well defined double-peaked HI profile.
KAZ 024: Described in original list as elliptical with compact nucleus. As in case of KAZ 23 we adopted a Sc morphological type according to LEDA. HI measured radial velocity confirms the value obtained by
Focardi et al. (1982) tex2html_wrap_inline1488 and differs from that obtained by Huchra et al. (1983) given in Table 1.
KAZ 026: Very strong but narrow emission lines in spectra, which are investigated in details by Shuder & Osterbrock (1981) and Kazarian & Tamazian (1982a). This object is very interesting and well investigated (see references in Table 1). Strong IRAS source (IRAS 07204+3332), FIR magnitude is 11.2 (IRAS Point Source Catalogue, 1988). Extremely blue with integral U-B=-0.86, B-V=+0.60, but certainly is not Seyfert type galaxy. HI profile is asymmetrical, due to an interference appearing only on part of the cycles (peak at tex2html_wrap_inline1494). However, the edges of the profile are not disturbed and the HI flux is only weakly affected.
KAZ 039: Lenticular, with bright nucleus. Our derived radial velocity is 350 km/s larger than the optical one obtained by Kazarian (1987). There are four galaxies lying within the Nançay beam: IC 1146 or MCG 12-15-19 (no known velocity, lenticular according to MCG) which might be the weak signal at tex2html_wrap_inline1496: UGC 10053 and MCG 12-15-21 with known (optical) radial velocities 11200 km/s and 10103 km/s respectively (LEDA) which cannot affect the detected signal: and MCG 12-15-18 which is elliptical (T=-5) with unkown velocity but probably with a very poor HI content.
KAZ 047: Compact dwarf galaxy surrounded by an heterogeneous extended halo. Very faint HI signal around the optical velocity tex2html_wrap_inline1500.
KAZ 052: Early spiral with bright nucleus. HI confusion due to NGC 6068 (Sbc galaxy, according to de Vaucouleurs et al. 1991), which was already measured at 21-cm with tex2html_wrap_inline1502 (Davis & Seaquist 1983; see also [2][40][26] for optical measurements). Poor S/N ratio and very uncertain edges of the line profile.
KAZ 060: Early spiral, 21-cm integration time of 80 cycles, but below detection level (S/N=1.5, for tex2html_wrap_inline1506). However, a hint of detection appears between V=8400 and 9100 km/s around the optical radial velocity listed in Table 1.

KAZ 063: Irregular, bright starlike condensation observed on the southern edge. Pair with UGC 10324 (type Sd) with tex2html_wrap_inline1510 ([43]) also detected within the beam as a separate signal. The HI profile of KAZ 063 is well distinguishable at lower velocities around tex2html_wrap_inline1512.
KAZ 065: Spiral with bright nucleus (4''). One of the arms ends to south with starlike condensations. Triangular HI profile. IC 1216 (no known velocity, Sc galaxy according to de Vaucouleurs et al. 1991) is also within the Nançay beam but no distorsion is observed. Our HI velocity confirms the value 7736 km/s obtained by Strauss & Huchra (1988), but differs from tex2html_wrap_inline1516 given by Kazarian (1987).
KAZ 069: Lenticular; a dark lane of width 1'' passing through the bright central part perpendicular to the lens. Wide HI line detected with S/N=3. Very close object with a small HI content.
KAZ 098: Elliptical with extension attached to the south-west edge, classified as a very peculiar object in UGC. HI signal well detected.
KAZ 120: Spiral galaxy with starlike condensation on the edge of the northern arm. Very poor HI detection (S/N=1.7, for tex2html_wrap_inline1524), however, the shape of the HI line is identified: a hint of signal between 4600 and 5100 km/s around the optical radial velocity (4800 km/s) listed in Table 1.
KAZ 198: Described as irregular, consisting of separate regions based on direct images taken on 2.6 m telescope of Byurakan observatory, whereas in LEDA appears as Sc. Emission lines of [SII], [OIII], tex2html_wrap_inline1414 and tex2html_wrap_inline1416 are present in the spectra. Total gas mass is about tex2html_wrap_inline1530 solar mass estimated by Kazarian (1984). Unusual HI profile with several separate peaks. HI confusion with the face-on Sa galaxy MCG 11-22-47 known to have tex2html_wrap_inline1532 ([23][25][26][48]), then, a corresponding narrow HI linewidth with a relatively high S/N ratio is expected. It could be the intermediate peak (near tex2html_wrap_inline1536) seen in the global observed wide profile. If, according to LEDA, KAZ 198 is an edge-on spiral, it is expected to have a wide HI profile, and a rather important HI flux: it probably contributes to the observed total width.
KAZ 201: One of the most faintest galaxies (tex2html_wrap_inline1538). Lenticular. KAZ 202 (tex2html_wrap_inline1540) in the off-field of comparison, but does not seem to disturb the signal. However, the HI profile is noisy, the low velocity edge is badly defined.
KAZ 211: Lenticular galaxy. Clear HI detection with an ill-defined edge at high velocity.
KAZ 216: Irregular, has six starlike knots.
KAZ 228: According to original list, it is a spiral galaxy with a bright circular nucleus (2.6 m telescope), but in LEDA it appears as elliptical. Faint HI signal (tex2html_wrap_inline1542) detected at tex2html_wrap_inline1544 thanks to very long integration time (212 cycles). Although NGC 7323 is within the beam, no HI confusion is possible because of very different radial velocity tex2html_wrap_inline1546 ([10][17][19][20][26]).
KAZ 236: Emission lines [NII] tex2html_wrap_inline1424 6584/48, tex2html_wrap_inline1414, [OIII] tex2html_wrap_inline1424 5007/4959 and tex2html_wrap_inline1416 are observed. Detailed spectral study (Kazarian & Tamazian 1982b) showed the lack of dust in this galaxy. We observed it in HI at tex2html_wrap_inline1556 as listed in Palumbo et al. (1983) (see Table 1). In fact, there is a single determination of its radial velocity which is tex2html_wrap_inline1558 (z=0.020), as given by Kazarian (1979) or Kazarian & Tamazian (1982b). The 21-cm spectrum shown in Fig. 2 (click here) is consequently not centered on the right velocity.
KAZ 248: Faint HI signal, suspected between 8900 and 9600 km/s around the optical radial velocity, but below detection level (tex2html_wrap_inline1562)
KAZ 282: Faint but well determined HI signal.
KAZ 291: Elliptical. No significant HI signal detected above tex2html_wrap_inline1564. KAZ 292 at the edge of the Nançay beam.
KAZ 305: Compact galaxy surrounded by faint halo. No HI signal detected above the level tex2html_wrap_inline1566.
KAZ 347: According to Humason et al. (1956)
NGC 7770 has a strong ultraviolet continuum of early type, broad and weak absorption lines of the Balmer series as well as weak emission at tex2html_wrap_inline1422 3727A [O II] which is possibly inclined. In pair with NGC 7771 located at 1.1 arcmin and disturbed; member of NGC 7769 group. Investigated photometricaly by Tamazian (1984). Integral colors U-B=+0.13, B-V=+0.49, but the bright nucleus is bluer with U-B=-0.27, B-V=+0.34. According to Humason et al. (1956) the radial velocity is tex2html_wrap_inline1578, but more precise measurements indicate smaller radial velocity tex2html_wrap_inline1580 (see Table 1). Our HI line appears disturbed. NGC 7771 (tex2html_wrap_inline1582, [7] [10] [17] [19] [22] [26] [29] [30] [37] [38] [42] [45]) is located within the Nançay beam and there is HI confusion: what is expected is a narrow emission from the face-on galaxy KAZ 347 = NGC 7770 (around tex2html_wrap_inline1584) superimposed on a relatively wide HI emission, centered at a nearby velocity, from the large inclined EW spiral NGC 7771. Note that Schneider et al. (1986) have observed the system
NGC 7769/7770/7771 at Arecibo (tex2html_wrap_inline1586) and state that NGC 7770 "has a broad peculiar wing on the high-velocity side of its HI profile''. This feature is also present here and is typical of interacting galaxies.
KAZ 368: Lenticular, with bright central region. No significant HI signal at the level tex2html_wrap_inline1588. Some hint of detection between 6000 and 6500 km/s around the optical radial velocity.
KAZ 445: Lenticular, probably with starlike nucleus. Well defined double-peaked HI profile, already published by Bottinelli et al. (1993).
KAZ 512: Starlike with very strong UV excess. Bright FIR source of magnitude 12. Despite very far distance, hint of HI detection around 15000 km/s near the optical radial velocity with S/N=2.3.
KAZ 520: Described as elliptical galaxy in original list, but Sc from LEDA. No significant HI signal at the level tex2html_wrap_inline1564.
KAZ 524: Spiral; another fainter elliptic galaxy at 50'' to the south. HI signal confused with that from KCPG 557A (tex2html_wrap_inline1596, Tifft 1982). The two HI profiles are superimposed: probably interacting galaxies.
KAZ 544: HI signal is very well detected. Although
ESO 533-48 (tex2html_wrap_inline1546, [8][35][49]) was at the edge of the Nançay beam, no HI confusion.
KAZ 546: Previously observed at 21-cm with tex2html_wrap_inline1602 and tex2html_wrap_inline1604 at tex2html_wrap_inline1606 (G. Paturel, unpublished). Our result is significantly different for the radial velocity (tex2html_wrap_inline1608).
KAZ 566: Well defined HI profile for such a far object.
KAZ 579: Elliptical galaxy confused with MCG 0-1-14 (very compact galaxy, classified as elliptical by LEDA) at tex2html_wrap_inline1610 ([2][24]). Our derived velocity tex2html_wrap_inline1612 confirms the optical radial velocity tex2html_wrap_inline1614 given in Arakelian et al. (1975).
