Figure 1:
Integrated HCN(1-0) emission ( black contours) overlaid
on CO(2-1) ( color scale; Schinnerer et al., in prep.,
García-Burillo et al. 2005) in natural ( left; a) and
uniform weighting ( right; b); the CO and HCN emission have been
both integrated from -200 km s-1 to +200 km s-1. We used a uv-taper for
CO to match the angular resolution of our HCN data which is by a
factor of 2 lower, and obtain identical beamsizes. Black
contours run from 3
to 23
( right: 7 )
in
steps of 1
Jy beam-1 km s-1 ( right:
1
Jy beam-1 km s-1); CO(2-1):
3
Jy beam-1 km s-1( right:
3
Jy beam-1 km s-1). The black line ( left)
indicates the major axis of the bar (PA = 100 )
and the grey line
the major axis of the galaxy (PA = 130 ). The black line (
right) represents the most extreme central velocity gradients
(PA = (160 ) ). The (0,0) position is at
37 14.123
and
06'20.09'' which is slightly different from the
phase centre of the observations. |
