Re:NGC 3894
The galaxy NGC 3894, classified as an E-S0, lies at a redshift of z= 0.010 75
(de Vaucouleurs et al. 1991). This is in agreement within the error of +/-30 km
s^-1^, with the redshift of z = 0.01068 determined by Karachentsev (1980).
Using multi-epoch VLBI observations, Taylor, Wrobel & Vermuelen (1998) suggest
that the radio source is oriented well away from the line of sight ({theta}
~50^deg^). Redshifted H I absorption has been detected towards both the
approaching and receding jets by Peck & Taylor (1998). Our GMRT spectrum (Fig.
10) shows the H I absorption towards this radio source. A good fit to the
absorption profile was obtained using six Gaussian components. The best-fitting
parameters are summarized in Table 7. Most of the absorption features are
redshifted with respect to the systemic velocity (~3220 km s^-1^) and could
represent the large-scale circumnuclear disc, as well as infall of clouds
towards the central engine (Peck & Taylor 1998).

Re:TXS 1146+596
1146+596. Its SED suggests that the non-thermal cut-off might
happen in the submillimetre regime. This is a core-dominated source
at JVAS resolution (0.2 arcsec). However, VLBI monitoring at
5 GHz revealed twin relativistic jets on a scale of milliarcseconds
(Taylor, Wrobel & Vermeulen 1998). We note that the absence of
large-scale radio emission in the NVSS map might indicate that this
is a young radio source.

Re:TXS 1146+596
1146+596 is a compact radio source for Condon & Dressel (1978). VLBI
observations at 5 GHz (Wrobel et al. 1985) suggest the presence of three
components consistent with an asymmetric core-jet structure; further
VLBI imaging of this source provided morphological and spectral evidence
leading to different conclusions - namely the presence of twin,
parsec-scale jets. The twin-jet kinematics requires that the jets are
mildly relativistic and oriented at ~50deg from the line-of-sight
(Taylor et al. 1998). 1146+596 has been included in the extragalactic
radio-jets catalogue of Liu & Zhang (2002); the optical counterpart of
this source is NGC 3894, a bright galaxy at z = 0.01068 classified as an
elliptical or an S0 (Nilson 1973). Although its optical continuum is
dominated by starlight, this galaxy's radio and far-infrared continuum
suggest the presence of an active nucleus (Condon & Broderick 1988).
Spectroscopic observations carried by Kim (1989) show the presence of a
dust lane and ionized gas along the galaxy's major axis; the gas
kinematics are rather peculiar, exhibiting non-circular motions. Analysis
of our data shows that the nuclear emission-line region has LINER
characteristics; such a low ionization spectrum could be associated with
a low power AGN.
