TL;DR
This study investigates whether low star formation activity isolated galaxies follow the established correlation between HCN luminosity and far-infrared luminosity, which is known for more active galaxies.
Contribution
The paper tests the applicability of the $L_{HCN}$-$L_{FIR}$ relation to low star formation, isolated galaxies using new HCN(1-0) emission observations.
Findings
Low $L_{FIR}$ IGs show deviations from the established correlation.
Results suggest the relation may not hold for galaxies with very low star formation.
Implications for understanding star formation in isolated galaxy environments.
Abstract
Low Isolated Galaxies (IGs) from the AMIGA sample have low level of Star Formation (SF) activity. We observed the HCN(1-0) emission in a sample of IGs in order to test whether they follow the tight relation between and found for galaxies with more active SF.
