8 note(s) found in NED.


1. 2002ApJS..143...73E
Re:NGC 2139
NGC 2139.---SBdm: No bulge. Asymmetric bar, oriented E-W (west end is
brighter than east end). Diffuse, patchy LSB spiral features appear
very disorganized. Direction of arm winding appears to change from the
inner to the outer disk. Two-armed pattern appears in outer disk. Disk
(and outer arms) has numerous star-forming knots.

Re:NGC 2139
NGC 2139.--The northern radio component coincides with the main body of this
galaxy. The southern peak lies on a bright knot or compact galaxy in the plume
extending south of the galaxy.

NGC 2139 is a clear case of a merger in
progress. The small satellite on one side of the
larger galaxy near its minor axis is seen best in
the light print on the right. The nuclear region of
this smaller galaxy is intact, and it has many
HII-region candidates along with evidence of
robust star formation. However its outer regions
appear to be tidally disrupted.
The main galaxy is also generally intact,
having a strong, chaotic bar and massive spiral
arms in which robust star formation is occurring.
However, there is a low-surface-brightness
straight (tidal?) plume extending about one
galaxy diameter beyond the main body of the
large galaxy, starting near the apparent point of
overlap of the two respective central regions.
The stellar content is about equally well
resolved in both galaxies.
The redshift, presumably of the central
region of the larger galaxy, is v_o = 1688 km/s.
