Dense gas in luminous infrared galaxies
W. A. Baan, C. Henkel, A. F. Loenen +2
Molecules that trace the high-density regions of the interstellar medium have been observed in (ultra-)luminous (far-)infrared galaxies, in order to initiate multiple-molecule mult…
Opportunities for maser studies with the Square Kilometre Array
A. J. Green, W. A. Baan
The Square Kilometre Array (SKA) is the radio telescope of the next generation, providing an increase in sensitivity and angular resolution of two orders of magnitude over existing…
Arp 220 - IC 4553/4: understanding the system and diagnosing the ISM
W. A. Baan
Arp220 is a nearby system in final stages of galaxy merger with powerful ongoing star-formation at and surrounding the two nuclei. Arp 220 was detected in HI absorption and OH Mega…
The irradiated ISM of ULIRGs
M. Spaans, R. Meijerink, F. P. Israel +2
The nuclei of ULIRGs harbor massive young stars, an accreting central black hole, or both. Results are presented for molecular gas that is exposed to X-rays (1-100 keV, XDRs) and f…
Molecular properties of (U)LIRGs: CO, HCN, HNC and HCO+
A. F. Loenen, W. A. Baan, M. Spaans
The observed molecular properties of a sample of FIR-luminous and OH megamaser (OH-MM) galaxies have been investigated. The ratio of high and low-density tracer lines is found to b…
HI and OH Absorption toward NGC6240
Willem A. Baan, Yoshiaki Hagiwara, Peter Hofner
VLA observations of large-scale HI and OH absorption in the merging galaxy of NGC6240 are presented with 1 arcsec resolution. HI absorption is found across large areas of the exten…
