HCO+ in the starburst galaxy M82.
SEAQUIST E.R., FRAYER D.T. and BELL M.B.
Abstract (from CDS):
The HCO+ (4-3)/(1-0) line ratios are comparatively uniform in the observed region, and according to a large velocity gradient analysis, reflect mean gas densities in the range 104-105 cm–3 for kinetic temperatures in the range 20-60 K. The comparative uniformity of these conditions and the low filling factor suggest that each sampled point comprises a large number of clouds occupying a broad range of density, and possibly temperature. We briefly examine fractal-type models in the context of the HCO+ data as an alternative way to analyze molecular line emission in M82.
