Scientific paper

The central region of NGC 1365 has been mapped in the J=3-2 CO emission line with the 15 m SEST, which has a HPBW of 15'' at the frequency of this transition. The observing grid has a 5 arcsec-spacing in the inner and a 10 arcsec-spacing in the outer region. A deconvolved map has been produced using the Maximum Entropy Method (MEM). A circumnuclear molecular torus with a radius of about 6\farcs 5 is the dominant feature. Molecular emission is also seen coming from various dust streamers in the bar of the galaxy. Four new molecular species have been detected in NGC 1365, namely HCN, HCO(+) , H_2CO and CS. (13) CO has also been observed in the nuclear region.
