Re:UGC 02855
UGC 2855 In this bright SABc spiral, the distribution of the ionized gas
is much stronger on the north-west side (we retrieve this difference on
the optical image). The isovelocity lines are symmetric with respect to
the minor and major axis. The solid-body part of the rotation curve
reaches 200 km s^-1^ at a radius of 35 arcsec (2.7 kpc); the rotation
curve remains symmetric until 60 arcsec, then the blueshifted side
(where H{alpha} shows the most important emission) rises and separates
from the red-shifted one that remains flat around 200 km s^-1^,
underlining a possible warp of its disk on one side. Indeed, the
velocity field derived by WHISP clearly shows a warp on the north-west
side beyond the optical limit probably caused by the vicinity of its
companion, UGC 2866 at 10 arcmin (90 kpc). The same remark can be made
for the disk of UGC 2866 which is warped. The star formation, mainly
localized in the west arm, together with the asymmetry of the rotation
curve and the disturbed HI disks of the two galaxies, clearly suggests
that they are interacting. The position-velocity diagram in the CO line
emission derived by Sofue et al. (1997) shows that the rotation curve is
flat after 30 arcsec, which is true if one considers the average of both
sides.

Re:UGC 02855
UGC 2855: This is an SBc type galaxy with high optical surface brightness,
associated with a companion (UGC 2866) at a distance of 10' (84 kpc) to the
east. CO intensity as strong as T_A_^*^~0.45 K has been observed in the central
part. The PV diagram shows a very steep rise to V_rot_~200 km s^-1^ within the
central ~7" (1 kpc). indicating rapidly rotating disk. The negative velocity
peak of this central disk attains a maximum velocity as high as
200 km s^-1^/sin i=200 km s^-1^ within the central few arcseconds. Besides this
steeply increasing component, the PV diagram indicates a rigid-body like ridge
with a velocity gradient of 170 km s^-1^/30" (4 kpc), followed by a flat
rotation part at 200 km s^-1^ at >30".

Re:UGC 02855
UGC 2855 (or A 0343) is a fairly inconspicuous Sc galaxy which drew attention
during the IRAS mission as strong far-infrared source. It forms a pair
together with UGC 2866 and both galaxies have been detected in the radio
continuum at 4.85 GHz by Condon et al. (1991). UGC 2855 exhibits significant
CO emission throughout the disk to large radii. Only the two outermost observed
ositions along the minor axis do not show any emission. These positions are,
however, outside the optical part of the disk.
