Determining star formation law in local galaxies with Arecibo

We propose to observe HCCCN 1-0 and 4 hydrogen radio recombination lines (RRLs) with X band receiver at Arecibo toward a sample of 13 galaxies with a wide range of infrared luminosity to study star formation law in local galaxies. HCCCN 1-0 can trace dense molecular gas, while RRLs would be the tracer of star foramtion rate in these galaxies. The most advantage of using HCCCN 1-0 and RRLs to study star formation law is that they are observed at the same time, which provide to cover the same region in galaxies, even if those galaxies are more extended than one beam of Arecibo, and also avoids time dependent uncertainties of telescopes. It will be an ideal pro ject for Arecibo to study star formation law.
