Abstract:
M82 is one of the nearest and brightest starburst galaxies. It has
been extensively studied in the past decade and by now is considered
the prototypical extragalactic photon-dominated region (PDR) and a
reference for studying star formation feedback.
Our aim is to characterize the molecular chemistry in M82 at spatial
scales of giant molecular clouds (GMCs), ∼100pc, to investigate the
feedback effects of the star formation activity.
Description:
We present interferometric observations of the CN 1->0 (113.491GHz),
N2H+ 1->0 (93.173GHz), H(41)α(92.034GHz), CH3CN
(91.987GHz), CS 3->2 (146.969GHz), c-C3H2 31,2->22,1
(145.089GHz), H2CO 20,2->10,1 (145.603GHz), and HC3N 16->15
(145.601GHz) lines carried out with the IRAM Plateau de Bure
Interferometer (PdBI).
