Abstract

Astronomy & Astrophysics Physical Sciences Science & Technology
We demonstrate the diagnostic value of para-formaldehyde (P-H2CO) as a tracer of the density and the temperature of molecular gas in external galaxies using the prototypical starburst, galaxy M 82 as an example. We also report, the discovery of the methanol line CH3OH(4(2) -> 3(1), E) from M 82.
