Abstract:
We present long baseline CO(1-0) mapping of the luminous infrared
galaxy NGC 6240 obtained with the IRAM - Plateau de Bure
Interferometer. This source is a well known early-stage merging system
hosting two active galactic nuclei (AGN). We find a broad CO(1-0)
line profile with maximum velocity 800km/s and a total line width of
1400km/s that displays several kinematic components, revealing the
complexity of the gas dynamics in this system. We detect a blueshifted
CO emission with velocity between -200 and -500 km/s, which peaks
around the southern AGN at the same position where the H2 outflow is
located. We interpret this blueshifted component as an outflow with a
mass loss rate of ∼500M☉/yr, originating from the southern
nucleus.
Description:
We used the Plateau de Bure Interferometer (PdBI) to observe the
CO(1-0) transition, redshifted to 112.516GHz assuming a systemic
velocity of 7339km/s which corresponds to a redshift of z=0.02448. The
observations were carried out in January 2012 with five antennas in
the extended (A) array configuration.
The spectral resolution is 10MHz.
Cleaned map produced in the GILDAS environment, using robust
weighting.
