Nitrogen hydrides such as NH\(_3\) and N\(_2\)H\(^+\) are widely used by Galactic observers to trace the cold dense regions of the interstellar medium. In external galaxies, because of limited sensitivity, HCN has become the most common tracer of dense gas over large parts of galaxies. We provide th...
