Abstract:
We aim for a better understanding of gas properties in the
circum-nuclear disk (CND) region of the nearby gas-rich Seyfert 2
galaxy NGC 1068. We focus on line identification and the basic
physical parameters estimation of molecular gas in the CND region.
Methods. We used the IRAM 30m telescope to conduct deep millimeter
spectroscopy observations toward the center of NGC 1068.
Description:
We present the results of 1-3mm molecular line survey towards
NGC1068. We show the final averaged spectra after eliminating bad
scans and subtracting baselines of order 0 to the individual spectra.
Y-axis is in antenna temperature scale.
