Abstract:
We aim for a better understanding of the imprints that the nuclear
activity in galaxies leaves in the molecular gas.
We used the IRAM 30m telescope to observe the frequency range
~[86-116]GHz towards the central regions of the star- burst galaxies
M83, M82, and NGC253, the galaxies hosting an active galactic
nucleus (AGN) M51, NGC1068, and NGC7469, and the ultra-luminous
infrared galaxies (ULIRGs) Arp220 and Mrk231. Assuming local
thermodynamic equilibrium (LTE), we calculated the column densities of
27 molecules and 10 isotopologues (or their upper limits in case of
non-detections).
Description:
We present the results of an IRAM 30m 3mm molecular line survey
towards the nuclei of the eight nearby active galaxies M83, NGC253,
M82, M51, NGC1068, NGC7469, Arp220, and Mrk231. Each file contains the
reduced spectra of one galaxy in fits format.

refer to the central one.
