| Abstract: |
The late-stage merger Mrk 273 has been known to host a powerful AGN
from its X-ray and mid-infrared spectroscopic signature. However, the
exact location of the AGN and the nature of its nucleus remain
uncertain due to the lack of available high-resolution data until
now. We present infrared integral-field spectra of the nuclear region of
Mrk 273 taken with OSIRIS on the Keck II Telescope with laser guide
star adaptive optics. We have analyzed the molecular and ionized gas
emission lines and derived their kinematics in two spatially-resolved
components. These results shed light on the AGN-starburst nature and
the physical conditions of the nuclear gas, lending support to the
potential scenario of dual AGN in this system. |
