AbstractWe present the detection of the ammonia (NH3) (J,K)= (1,1) to (4,4) and (6,6) inversion lines toward the prototypical Seyfert 2 galaxy NGC 1068, made with the Green Bank Telescope (GBT). This is the first detection of ammonia in a Seyfert galaxy. The ortho-to-para-NH3 abundance ratio suggests that the molecule was formed in a warm medium of at least 20 K. For the NH3 column density and fractional abundance, we find (1.09 +/- 0.23) x 10(14) cm(-2) and (2.9 +/- 0.6) x 10(-8), respectively, from the inner similar to 1.2 kpc of NGC 1068. The kinetic temperature can be constrained to 80 +/- 20 K for the bulk of the molecular gas, while some fraction has an even higher temperature of 140 +/- 30 K.
