The radio properties of the OH megamaser galaxy IRAS 02524+2046
  We present results from VLBI observations of continuum and OH line emission
in IRAS 02524+2046 and also arcsecond-scale radio properties of this galaxy
using VLA archive data. We found that there is no significant detection of
radio continuum emission from VLBI observations. The arcsecond-scale radio
images of this source show no clear extended emission, the total radio flux
density at L and C band are around 2.9 mJy and 1.0 mJy respectively, which
indicate a steep radio spectral index between the two band. Steep spectral
index, low brightness temperature and high $q$-ratio (the FIR to the radio flux
density), which are three critical indicators in classification of radio
activity in the nuclei of galaxies, are all consistent with the classification
of this source as a starburst galaxy from its optical spectrum. The
high-resolution line profile show that both of \textbf{the 1665 and 1667 MHz OH
maser} line have been detected which show three and two clear components
respectively. The channel maps show that the maser emission are distributed in
a region $\sim$ 210 pc $\times$ 90 pc, the detected maser components at
different region show similar double spectral feature, which might be an
evidence that this galaxy is at a stage of major merger as seen from the
optical morphology.
